Mercedes-Benz E-class 1998 User Manual

Important!

With selector lever in position "D", "4"
or "3", upshifting from 1st to 2nd to 3rd
gear is delayed depending on vehicle
speed and engine temperature. This
allows the catalytic converter to heat up
more quickly to operating temperatures.

During the brief warm-up period this
delayed upshift and increased engine
noise might be perceived as a
malfunction. However, neither the
engine nor transmission are negatively
affected by this mode of operation.
The delayed upshift is effective with
vehicle speeds below 31 mph (50 km/h)
at partial throttle and engine
temperatures below 95°F (35°C).
To avoid overrevving the engine when
the selector lever is moved to a lower
driving range, the transmission will not
shift to a lower gear as long as the
vehicle speed exceeds the speed limit of
that gear.

To prevent the engine from laboring at
low RPMs, do not allow the engine
speed to drop too low on uphill
gradients.

Depending on the degree of the incline,

shift selector lever to a lower gear
range early enough to maintain engine
RPM within the best torque range.

Warning!

On slippery road surfaces, never
downshift in order to obtain braking
action. This could result in rear
wheel slip and reduced vehicle
control. Your vehicle's ABS will not
prevent this type of loss of control.

Maneuvering

To maneuver in tight areas, e.g. when
pulling into a parking space, control
the car speed by gradually releasing the
brakes. Accelerate gently and never
abruptly step on the accelerator.
To rock a car out of soft ground (mud
or snow), alternately shift from
forward to reverse, while applying
slight partial throttle.

Rocking a car free in this manner may
cause the ABS malfunction indicator
lamp to come on. Turn off and restart
the engine to clear the malfunction
indication.

Stopping

For brief stops, e.g. at traffic lights,
leave the transmission in gear and hold
vehicle with the service brake.

For longer stops with the engine idling,
shift into "N" or "P" and hold the
vehicle with the service brake.

When stopping the vehicle on an uphill
gradient, do not hold it with the
accelerator, use the brake. This avoids
unnecessary transmission heat build up.

Warning!

Getting out of your car with the
selector lever not fully engaged in
position "P" is dangerous. Also,
when parked on an incline, position
"P" alone may not prevent your
vehicle from moving, possibly hitting
people or objects.

Always set the parking brake in
addition to shifting to position "P".

When parked on an incline, also turn
front wheel against curb.

Program Mode Selector Switch

when

The transmission is provided with a
selector switch for Standard "S" and
Winter/Wet (snow and ice) "W"
program modes.

Warning!

Always be certain of the program mode
selected since the vehicle driving
characteristics change with the
selection of the program mode.

S Standard mode

Press switch on symbol "S". Use
this mode for all regular driving.
The vehicle starts out in 1st gear.

W Winter/Wet (snow and ice) mode

Press switch on symbol "W". The
vehicle starts out in 2nd gear,
except with selector lever in 1 st
gear, or with accelerator pedal in
kick-down position.

The "W" mode helps to improve
traction and driving stability of the
vehicle.

With hard acceleration the upshifts
occur at lower vehicle and engine
speeds than in the "S" program
mode.

Caution!

Never change the program mode
the selector lever is out of position "P".
It could result in a change of driving
characteristics for which you may not
be prepared

Emergency Operation

(Limp Home Mode)

If vehicle acceleration worsens, or the
transmission no longer shifts, the
transmission is most likely operating
in Limp Home Mode which engages
when there is a malfunction at the
transmission. This condition may be
accompanied by the "CHECK
ENGINE" malfunction indicator lamp
in the instrument cluster coming on.
In this mode only the 2nd gear or
reverse gear can be activated.

To engage 2nd gear or reverse:

1. Stop the vehicle.

2. Move selector lever to

position "P".

3. Turn off the engine.

4. Wait 10 seconds.

5. Restart the engine.

6. Move selector lever to

position "D" (for 2nd gear), or
move selector lever to
position "R" (for reverse gear).

Have the transmission checked at
your authorized Mercedes-Benz
dealer as soon as possible.

Cruise Control

Any given speed above approxi
mph (40 km/h) can be
cruise control by operating the lever.

1 Accelerate and set:

Lift lever briefly to set speed. Hold
lever up to accelerate.

2 Decelerate and set:

Depress lever briefly to set
speed.
Hold lever down to decelerate

Normally the vehicle is accelerated to

the desired speed with the accelerator.
Speed is set by briefly pushing the lever

to position 1 or 2. The accelerator can
be released.

The speed can be increased (e.g. for
passing) by using the accelerator. After
the accelerator is released, the
previously set speed will be resumed
automatically.

If a set speed is to be increased or
decreased slightly, e.g. to adapt to the
traffic flow, hold lever in position 1 or 2
until the desired speed is reached, or
briefly tip the lever in the appropriate
direction for increases or decreases in

0.6 mph (1 km/h) increments. When the
lever is released, the newly set speed
remains.

3 Canceling

To cancel the cruise control, briefly
push lever to position 3.

When you step on the brake pedal
or the vehicle speed drops below
approx. 25 mph (40 km/h), for
example when driving upgrade, the
cruise control will be canceled.

If the cruise control cancels by itself
and remains inoperative until the
engine is restarted, have the system
checked at your authorized
Mercedes-Benz dealer as soon as
possible.

4 Resume

If the lever is briefly pushed to
position 4 when driving at a speed
exceeding approx. 25 mph (40
km/h), the vehicle resumes the
speed which was set prior to the
cancellation of the cruise control.
The last memorized speed is
canceled when the electronic key in
the steering lock is turned to
position 1 or 0.

83

Notes:
If the engine does not brake the vehicle

sufficiently while driving on a
downgrade, the speed you set on the
cruise control may be exceeded and
you may have to step on the brake
pedal to slow down. As soon as the
grade eases, the cruise controlled speed
will again be maintained as long as the
brakes were not previously applied, or
the lever may be used to resume the
previously set speed if the brakes were
applied.

Important!

Moving gear selector lever to position
"N" switches the cruise control off.

Warning!

Only use the cruise control if the
traffic and weather conditions make
it advisable to travel at a steady
speed.

• The use of cruise control can be

dangerous on winding roads or
in heavy traffic because
conditions do not allow safe
driving at a steady speed.

• The use of cruise control can be

dangerous on slippery roads.
Rapid changes in tire adhesion
can result in wheel spin and loss
of control.

The "Resume" function should only
be operated if the driver is fully
aware of the previously set speed and
wishes to resume this particular
preset speed.

84

Parking Assist (Parktronic)
(optional)

The Parktronic assists the driver during
parking maneuvers at low speeds. It
visually and audibly indicates the
distance between the vehicle and an
obstacle.

The front area of the vehicle is
monitored when driving forward.
When reversing, the front as well as
the rear areas are monitored.

With the electronic key in steering lock
position 2, the Parktronic engages
automatically at speeds up to approx.
10 mph (15 km/h) and deactivates
during higher speeds.

The Parktronic can be switched off by a
control switch located in the center
console.

Warning!

Parktronic is a supplemental system.
It is not intended to nor does it
replace the need for extreme care.
The responsibility during parking
and other critical maneuvers rests
always with the driver.

Special attention must be paid to
objects having smooth surfaces or
low silhouettes (e.g. trailer couplings,
painted posts, or street curbs). Such
objects may not be detected by the
system and can damage the vehicle.
The operational function of the
Parktronic can be affected by dirty
sensors, especially at times of snow
and ice.

Interference caused by other
ultrasonic signals (e.g. working
jackhammers or the air brakes of
trucks) should be taken into
consideration.

Sensors

A total of 10 sensors monitor the
vehicle front and rear areas. Six sensors
are located in the front bumper, four in
the rear bumper.

1 Sensor located in bumper

For proper operation of the Parktronic
always keep the sensors clean.

Use a mild car wash detergent, such as
Mercedes-Benz approved Car
Shampoo, with plenty of water.
When using a steam cleaner or power
washer, aim nozzle only briefly from a
minimum distance of 4 in. (10 cm) at
sensors.

To prevent scratches, never apply
strong force or use a hard cloth when
cleaning the sensors. Do not attempt to
wipe dirty sensors with a dry cloth or
sponge.

When the symbol and message appear
while the engine is running, this
indicates a fault which must be repaired
at an authorized Mercedes-Benz dealer
immediately.

It may indicate that the poly-V-belt has
broken. Should this condition occur,
the poly-V-belt must be replaced before
continuing to operate the vehicle.
Otherwise, the engine will overheat due
to an inoperative water pump which
may result in damage to the engine.

Do not continue to drive the vehicle
with the charge indicator symbol
displayed. Doing so could result in
serious engine damage that is not
covered by the Mercedes-Benz Limited
Warranty.

Low Engine Oil Level Warning

When the symbol and message appear
while the engine is running and at
operating temperature, the engine oil
level has dropped to approximately the
minimum mark on the dipstick.

When this occurs, the warning will first

come on intermittently and then stay on
if the oil level drops further.
If no oil leaks are noted, continue to
drive to the nearest service station
where the engine oil should be topped
to the "full" mark on the dipstick with
an approved oil.

The low engine oil level warning
not be ignored. Extended driving with
the symbol displayed could result in
serious engine damage that is not
covered by the Mercedes-Benz Limited
Warranty.

In addition to the warning symbol, the
engine oil level should be periodically
checked with the dipstick or via the
multifunction indicator, for example
during a fuel stop, or before a long trip
(see Index).

Note:
E 300 Turbodiesel - Oil level check via

multifunction indicator not possible.
Engine Oil Consumption
Engine oil consumption checks should

only be made after the break-in period.
During the break

in period, higher oil consumption may

be noticed and is normal. Frequent
driving at high engine speeds results
in increased consumption.

Fuel Reserve and Fuel Cap
Placement

Warning

When the symbol and message appear
after starting the engine, or if it comes
on while driving, it indicates that the
fuel level is down to the reserve
quantity of approximately: 2.6 gal (10
liters).

The warning lamp blinks when the fuel
cap is not closed, or a fuel system leak
has been detected. Retighten cap and
see if lamp goes out.

If the warning lamp continues to blink
after closing the fuel cap correctly,
have the fuel system checked at your
authorized Mercedes-Benz dealer as
soon as possible.

Leaving the engine running and the fuel
cap open can cause the "Check Engine"
lamp to illuminate.

the driver and passengers to fasten seat
belts.

Outside Temperature Indicator

The temperature sensor is located in the
front bumper area. Due to its location,
the sensor can be affected by road or
engine heat during idling or slow
driving. This means that the accuracy of
the displayed temperature can only be
verified by comparison to a
thermometer placed next to the sensor,
not by comparison to external displays
(e.g. bank signs etc.).

place in steps and depends on the
prevailing driving conditions (stop-and­go or moderate, constant driving) and
amount of temperature change.

Warning!

The outside temperature indicator is
not designed to serve as an Ice­Warning Device and is therefore un­suitable for that purpose. Indicated
temperatures just above the freezing
point do not guarantee that the road
surface is free of ice.

Coolant Temperature Gauge

If the antifreeze mixture is effective to

-22°F (-30°C), the boiling point of the
coolant in the pressurized cooling
system of your vehicle is approx.
266°F (130°C).

During severe operating conditions and
stop-and-go city traffic, the coolant
temperature may rise close to the red
marking.

The engine should not be operated with
the coolant temperature in the red zone.
Doing so may cause serious engine
damage which is not covered by the
Mercedes-Benz Limited Warranty.

90

Warning!

• Driving when your engine is badly

overheated can cause some fluids
which may have leaked into the
engine compartment to catch fire.
You could be seriously burned.

• Steam from an overheated engine

can cause serious burns and can
occur just by opening the engine
hood. Stay away from the engine
if you see or hear steam coming
from it.

Turn off the engine, get out of the car
and do not stand near the car until it
cools down.

Low Engine Coolant Level

Warning

When the symbol and message appear
while driving, then the coolant level
has dropped below the required level.
If no leaks are noticeable and the
engine temperature does not increase,
continue to drive to the nearest service
station and have coolant added to the
coolant system (see Index).

The low engine coolant level warning
should not be ignored. Extended
driving with the symbol displayed may
cause serious engine damage not
covered by the Mercedes-Benz Limited
Warranty.

In cases of major or frequent minor
coolant loss, have the cooling system
checked at your authorized Mercedes­Benz dealer as soon as possible.

Note:
Do not drive without coolant in the

cooling system. The engine will
overheat causing major engine damage.
Monitor the coolant temperature gauge
while driving.

Warning!

Do not spill antifreeze on hot engine
parts. Antifreeze contains ethylene
glycol which may burn if it comes
into contact with hot engine parts.
You can be seriously burned.

Low Windshield and Headlamp
Washer System Fluid Level Warning

When the symbol and message appear
while the engine is running, the level of
the reservoir has dropped to approx. 1/3
of the total volume. The reservoir
should be refilled with MB Windshield
Washer Concentrate "S" and water (or
commercially available premixed
windshield washer solvent/antifreeze,
depending on ambient temperature ­see Index) at the next opportunity. The
reservoir for the windshield and
headlamp washer systems is located in
the engine compartment.

When the symbol and message appear
while driving, this symbol indicates a

failure in the parking lamp, taillamps,
stop lamp, or low beam headlamp.

If an exterior lamp fails, the indicator
symbol will come on only when that
lamp is switched on.

If a brake lamp fails, the lamp failure
indicator will come on when applying
the brake and stays on until the engine is
turned off.

Note:
If additional lighting equipment is

installed (e.g. auxiliary headlamps etc.)

order to avoid damaging the system.

Brake Pad Wear Indicator

When the symbol and message appear
during braking, this indicates that the
brake pads are worn down.

Have the brake system checked at your
authorized Mercedes-Benz dealer as
soon as possible.

Brake Warning

When the brake warning lamp and
message appear while the engine is
running, this means:

• there is insufficient brake fluid in

the reservoir (engine running
and parking brake released), or

• the parking brake is set (engine

running).

Warning!

Driving with the brake warning
lamp illuminated can result in an
accident. Have your brake system
checked immediately if the brake
warning lamp stays on. Don't add
brake fluid before checking the
brake system. Overfilling the brake
fluid reservoir can result in spilling
brake fluid on hot engine parts and
the brake fluid catching fire. You
can be seriously burned.

Note:
If you find that the minimum mark on

the brake fluid reservoir is reached,
have the brake system checked for
brake pad thickness and leaks.

92

Flexible Service System (FSS)

The FSS permits a flexible service
schedule that is directly related to the
operating conditions of the vehicle.

The symbol appears together with
a message in the multifunction indicator
prior to the next suggested service.
Depending on operating conditions
throughout the year, the next service is
calculated and displayed in days or
distance remaining.

The message is displayed for approx.
10 seconds when turning the electronic
key in steering lock to position 2, or it
can be canceled manually by pressing
button 0.

Once the suggested term has passed,
the symbol plus message
"EXCEEDED BY" appear, when turning
the electronic key to position 2.

The FSS display can also be called up
for approx.10 seconds with display
illuminated by pressing button 0 twice.

Following a completed service the

Mercedes-Benz dealer sets the counter
to 10 000 miles (Canada: 15 000 km)
and 365 days.

The counter can also be set by any
individual. To do so:

1. Turn electronic key in steering

lock to position 2.

2. Within 4 seconds press button 0

twice.

3. The present status for days or

distance is displayed. Within
10 seconds turn electronic key in
steering lock to position 0.

4. Press and hold button 0, while

turning electronic key in steering
lock to position 2 again. The pre
sent status for days or distance
is displayed once more. Continue
to hold button 0.
After approx. 10 seconds a signal
sounds, and the display shows
10 000 miles (Canada: 15 000 km).

5. Release button 0.
If the FSS counter was inadvertently

reset, have a Mercedes-Benz dealer
correct it.

93

Notes:

When disconnecting vehicle battery for
one or more days at a time, such days
will not be counted. Any such days not
counted by the FSS can be added by
your Mercedes-Benz dealer. The
interval between services is determined
by the kind of vehicle operation.
Driving at extreme speeds, and cold
starts combined with short distance
driving in which the engine does not
reach normal operating temperature,
reduce the interval between services.

Models E 320 and E 430:

The FSS allows for distances between
10 000 miles (Canada: 15 000 km) and
20 000 miles (Canada: 30 000 km), or
from 365 to 730 days between services.

Model E 300 TURBODIESEL:
The FSS allows for distances between

10 000 miles (Canada: 15 000 km) and
15 000 miles (Canada: 22 500 km), or
from 365 to 730 days between services.

However you choose to set your

reference numbers, the scheduled
services as posted in the Service
Booklet must be followed to properly
care for your vehicle.

94

Antilock Brake System (ABS)

electronic key in steering lock position 2

indicator lamps come on with the engine

Important!

The ABS improves steering control of
the vehicle during braking maneuvers.
Do not pump the brake pedal, rather
use firm, steady brake pedal pressure.
Pumping the brake pedal defeats the
purpose for ABS and significantly
reduces braking effectiveness.

The ABS prevents the wheels from
locking up above a vehicle speed of
approximately 5 mph (8 km/h)
independent of road surface conditions.

At the instant one of the wheels is
about to lock up, a slight pulsation can
be felt in the brake pedal, indicating
that the ABS is in the regulating mode.
Keep firm and steady pressure on the
brake pedal while experiencing the
pulsation.

On slippery road surfaces, the ABS will
respond even with light brake pedal
pressure because of the increased
likelihood of locking wheels. The
pulsating brake pedal can be an
indication of hazardous road conditions
and functions as a reminder to take
extra care while driving.

ABS Control

The ABS malfunction indicator lamp in
the instrument cluster comes on with the

and should go out with the engine
running.

When the ABS malfunction indicator
lamp symbol and warning in the
instrument cluster come on while the
engine is running, it indicates that the
ABS has detected a malfunction and has
switched off. In this case, the brake
system functions in the usual manner,
but without antilock assistance.

With the ABS malfunctioning, the BAS,
ASR or ESP, if vehicle so equipped, are
also switched off. Both malfunction

running.
If the charging voltage falls below 10

volts, the malfunction indicator lamp
comes on and the ABS is switched off.
When the voltage is above this value
again, the malfunction indicator lamp
should go out and the ABS should be
operational.
Have the system checked at your
authorized Mercedes-Benz dealer as
soon as possible.

Warning!

ABS cannot prevent the natural laws
of physics from acting on the vehicle,
nor can it increase the traction made
available by the road conditions. The
ABS cannot prevent accidents,
including those resulting from
excessive speed in turns, following
another vehicle too closely, or
aquaplaning. Only a safe, attentive,
and skillful driver can prevent
accidents. The capabilities of an ABS
equipped vehicle must never be
exploited in a reckless or dangerous
manner which could jeopardize the
user's safety or the safety of others.

Note:
To alert following vehicles to slippery

road conditions you discover, operate
your hazard warning flashers as
appropriate.

95

Brake Assist System (BAS)

Warning!

BAS cannot prevent the natural laws
of physics from acting on the vehicle,
nor can it increase braking efficiency
beyond that afforded by the
condition of the vehicle brakes and
tires or the traction afforded. The
BAS cannot prevent accidents,
including those resulting from
excessive speed in turns, following
another vehicle too closely, or aqua­planing. Only a safe, attentive, and
skillful driver can prevent accidents.
The capabilities of a BAS equipped
vehicle must never be exploited in a
reckless or dangerous manner which
could jeopardize the user's safety or
the safety of others.

The BAS is designed to maximize the

vehicle's braking capability during
emergency braking maneuvers by
having maximum power boost applied
to the brakes more quickly in
emergency braking conditions than
might otherwise be afforded solely by
the driver's braking style. This can help
reduce braking distances over what
ordinary driving and braking style
might do. The BAS complements the
Antilock Brake System (ABS).

To receive the benefit of the system
you must apply continuous full braking
power during the stopping sequence.

Do not reduce brake pedal pressure.

Once the brake pedal is released, the
BAS is deactivated

The malfunction indicator lamps for
the ASR or ESP are combined with the
BAS malfunction indicator lamp.

The BAS/ASR or BAS/ESP
malfunction indicator lamp in the
instrument cluster comes on with the
electronic key in steering lock position
2 and should go out with the engine
running.

If the BAS/ASR or BAS/ESP

malfunction indicator lamp comes on
permanently while the engine is
running, a malfunction has been
detected in either system. As a result, it
is possible that now only partial engine
output will be available, and pressing
the accelerator pedal will require more
effort. If the BAS malfunctions, the
brake system functions in the usual
manner, but without BAS.

If the charging voltage falls below 10
volts, the malfunction indicator lamp
comes on and the BAS is switched off.
When the voltage is above this value
again, the malfunction indicator lamp
should go out and the BAS is
operational.

With the ABS malfunctioning, the
BAS, ASR or ESP are also switched
off. Both malfunction indicator lamps
come on with the engine running.

Have the BAS, ASR or ESP checked at
your authorized Mercedes-Benz dealer
as soon as possible.

96

Electronic Traction System (ETS)

(Model E320 with All Wheel Drive
[AWD]: 4-ETS)

The 4-ETS improves vehicle's ability
to utilize available traction, especially
under slippery road conditions. The
brakes are applied to the spinning
wheel and power is transferred to the
wheel(s) with traction. At
approximately 50 mph (80 km/h), the
ETS switches off at the front wheels,
and at approximately 80 mph (130
km/h) at the rear wheels.
The ETS warning lamp, located in the
speedometer dial, starts to flash at
any vehicle speed, as soon as the
tires lose traction and the wheels
begin to spin.

Important!
If the ETS warning lamp flashes:

• during take-off, apply as little

throttle as possible,

• while driving, ease up on the

accelerator.
Adapt your speed and driving to the
prevailing road conditions.

ETS Control
If the yellow BAS/ETS malfunction
indicator lamp comes on while the

ETS warning lamp flashes, with the

engine running, the electronic traction
system is being switched off
temporarily on one ore more wheels
to prevent overheating of the drive
wheel brakes.

If the BAS/ETS malfunction indicator
lamp comes on permanently with the
engine running, a malfunction has
been detected in either system.
If the BAS malfunctions, the brake
system functions in the usual manner,
but without BAS.
Have the BAS or ETS checked at your
authorized Mercedes-Benz dealer as
soon as possible.

With the ABS malfunctioning, the ETS
is also switched off.

Caution!

Model E320 with AWD: 4-ETS
Operational tests with the engine
running can only be conducted on a 2­axle dynamometer. Otherwise the 4­ETS applies the brakes to the spinning
wheels.
If the vehicle is towed with one axle
raised (see Towing the vehicle in
Index), or when testing the parking
brake on a brake test dynamo

meter, the engine must be shut off

(electronic key in steering lock
position 0 or 1). Otherwise, the
electronic traction system will
immediately be engaged and will
apply the brakes.

Notes:
The indicator lamp for the ETS is
combined with that of the BAS
The yellow BAS/ETS malfunction
indicator lamp in the instrument
cluster and the yellow ETS warning
lamp in the speedometer dial come
on with the electronic key in steering
lock position 2. They should go out
with the engine running.
Driving the vehicle with varied size
tires will cause the wheels to rotate at
different speeds, therefore the
acceleration slip regulation may
activate (yellow ETS warning lamp in
speedometer dial comes on). For this
reason, all wheels, including the
spare wheel, must have the same tire
size.

In winter operation, the maximum
effectiveness of the four wheel
electronic traction system is only
achieved with Mercedes-Benz
recommended M+S rated radial-ply
tires and/or snow chains.

Acceleration Slip Regulation (ASR)

The acceleration slip regulation will
engage at all vehicle speeds, if one or
both drive wheels begin to lose traction
and spin due to excessive acceleration.
While engaged, the yellow warning
lamp in the speedometer flashes.

With the acceleration slip regulation
engaged, the brake is applied to the
spinning drive wheel until it regains
sufficient traction. If both drive wheels
lose traction and spin, the brake is
applied to both drive wheels and
simultaneously, engine torque is
limited, to improve the vehicle's
driving stability.

As traction on the road surface
increases, the allowable engine torque
also increases again and the brake is no
longer applied to drive wheels.

Important!

If the ASR warning lamp flashes, adapt
your speed and driving to the
prevailing road conditions.

Caution!

If the vehicle is towed with the front
axle raised (see Towing the vehicle in
Index), the engine must be shut off
(electronic key in steering lock position
0 or 1). Otherwise, the acceleration slip
regulation will immediately be engaged
and will apply the rear wheel brakes.

Notes:
The indicator lamp for the ASR is

combined with that of the BAS

2. They should go out with the engine
running.

If the BAS/ASR malfunction indicator
lamp comes on with the engine running,
a malfunction has been detected in
either system. Pressing the accelerator
pedal will require greater effort. Only
partial engine output will be available.

If the BAS malfunctions, the brake

system functions in the usual manner,
but without BAS.

Have the BAS or ASR checked at your
authorized Mercedes-Benz dealer as
soon as possible.

With the ABS malfunctioning, the
ASR is also switched off.

Driving the vehicle with varied size
tires will cause the wheels to rotate at
different speeds, therefore the
acceleration slip regulation may
activate (yellow ASR warning lamp in
speedometer dial comes on). For this
reason, all wheels, including the spare
wheel, must have the same tire size.

When testing the parking brake on a
brake test dynamometer, the engine
must be shut off. Otherwise, the
acceleration slip regulation will
immediately be engaged and will apply
the rear wheel brakes.
In winter operation, the maximum
effectiveness of the acceleration slip
regulation is only achieved with
Mercedes-Benz recommended M+S
rated radial-ply tires and/or snow
chains.

stability offered by ASR: press lower
half of the switch (the ASR warning
lamp in the speedometer dial goes out).

Important!
If the ASR warning lamp flashes:

• during take-off, apply as little

throttle as possible,

• while driving, ease up on the

accelerator.

99

Electronic Stability Program
(ESP) (optional)

The ESP enhances directional control
and reduces driving wheel spin of the
vehicle under any driving condition.

Over/understeering of the vehicle is
counteracted by applying brakes to the
appropriate wheel to create a
counterpointing vehicle movement.
The ESP warning lamp, located in the
speedometer dial, starts to flash.

Important!

If the ESP warning lamp flashes, adapt
your speed and driving to the
prevailing road conditions.

Caution!

If the vehicle is towed with the front

101

Emission Control

Certain systems of the engine serve to
keep the toxic components of the
exhaust gases within permissible limits
required by law.

These systems, of course, will function
properly only when maintained strictly
according to factory specifications.
Any adjustments on the engine should,
therefore, be carried out only by
qualified Mercedes-Benz authorized
dealer technicians. Engine adjustments
should not be altered in any way.
Moreover, the specified service jobs
must be carried out regularly according
to Mercedes-Benz servicing
requirements. For details refer to the
Service Booklet.

Warning!

Inhalation of exhaust gas is
hazardous to your health. All
exhaust gas contains carbon
monoxide, and inhaling it can cause
unconsciousness and lead to death.

Do not run the engine in confined
areas (such as a garage) which are
not properly ventilated. If you think
that exhaust gas fumes are entering
the vehicle while driving, have the
cause determined and corrected
immediately. If you must drive
under these conditions, drive only
with at least one window fully open.

On-Board Diagnostic System

Vehicles with Diesel engine

When the "CHECK ENGINE" mal­function indicator lamp comes on while
the engine is running, this indicates a
malfunction in the fuel injection system.
Only partial engine output is available.
Have the system checked at your
authorized Mercedes-Benz dealer as
soon as possible.

Vehicles with gasoline engine

The Sequential Multiport Fuel Injection
(SFI) control module monitors emission
control components that either provide
input signals to or receive output signals
from the control module. Malfunctions
resulting from interruptions or failure of
any of these components are indicated
by the "CHECK ENGINE" malfunction
indicator lamp in the instrument cluster
and are simultaneously stored in the
diagnostic module.

If the "CHECK ENGINE" malfunction
indicator lamp comes on, have the
system checked at your authorized
Mercedes-Benz dealer as soon as
possible.

The control module switches off the
"CHECK ENGINE" indicator lamp if the
condition, causing the lamp to come on,
no longer exists.

An on-board diagnostic connector is
located in the passenger compartment
near to the parking brake pedal,
allowing the accurate identification of
system malfunctions through the readout
of diagnostic trouble codes.

102

Winter Driving

Have your vehicle winterized at your
authorized Mercedes-Benz dealer
before the onset of winter.

• Change the engine oil if the engine

contains an oil which is not
approved for winter operation. For
viscosity (SAE/CCMC class) and
filling quantity, see Capacities:
Fuels, Coolants, Lubricants etc. in
Index.

• Check engine coolant anticorrosion/

antifreeze concentration.

• Additive for the windshield washer

and headlamp cleaning system: Add
MB Concentrate "S" to a premixed
windshield washer solvent/
antifreeze which is formulated for
below freezing temperatures (see
Index).

• Test battery: Battery capacity
drops with decreasing ambient
temperature. A well charged
battery helps to ensure that the
engine can be started, even at low
ambient temperatures.

• Tires: We recommend M+S rated

radial-ply tires on all four wheels
for the winter season. Observe
permissible maximum speed for
M+S rated radial-ply tires and the
legal speed limit.

Note:

In winter operation, the maximum
effectiveness of the acceleration slip
regulation or of the electronic traction
system can only be achieved with M+S
radial-ply tires and/or snow chains
recommended by Mercedes-Benz.
Snow chains maximize performance.

Vehicles with diesel engine –

• For diesel fuels, refer to Index.

• Engine block heater:

The engine is equipped with a
block heater. The electrical cable
may be installed free-of-charge at
your authorized Mercedes-Benz
dealer by using the coupon in the
"Owner's Service and Warranty
Policy" booklet. The coupon is valid
for 12 months from date of vehicle
delivery.

103

Snow Chains

Use only snow chains that are tested
and recommended by Mercedes-Benz.
Your authorized Mercedes-Benz dealer
will be glad to advise you on this
subject.

Chains should only be used on the rear
wheels. Follow the manufacturer's
mounting instructions.

Snow chains should only be driven on
snow covered roads at speeds not to
exceed 30 mph (50 km/h). Remove
chains as soon as possible when
driving on roads without snow.

For tips on driving on slippery winter

roads, refer to Index.
Vehicles with Acceleration Slip

Regulation (ASR) or Electronic
Stability Program (ESP):

When driving with snow chains, press
the ASR control switch or the ESP
control switch, refer to Index.

Model E430 with Sport Package
Use only the MB authorized special

snow chain with tire size
235/45 ZR 17.

Traveling Abroad

Abroad, there is a widely-spread
Mercedes-Benz service network at
your disposal. If you plan to travel into
areas which are not listed in the index
of your dealer directory, you should
request pertinent information from
your authorized Mercedes-Benz dealer.

Practical Hints

105

pull

Warning!

To help prevent personal injury,
stay clear of moving parts when the
hood is open and the engine is
running. Be sure the hood is properly
closed before driving. When closing
hood, use extreme caution not to
catch hands or fingers.

If you see flames or smoke coming
from the engine compartment, or if
the coolant temperature gauge
indicates that the engine is
overheated, do not open the hood.

Hood

To open:
To unlock the hood, pull release lever

(1) under the driver's side of the
instrument panel. At the same time
handle (2) will extend out of the
radiator grill (it may be necessary to lift
the hood up slightly).

Caution!
To avoid damage to the windshield

wiper or hood, open the hood only with
wiper in the parked position.

Pull handle (2) completely out of

radiator grill and open hood (do not
up on handle).

To close:
Lower hood and let it drop into lock
from a height of approx. 1 ft. (30 cm),
assisting with hands placed flat on
edges of hood (3).

To avoid hood damage, if hood is not
fully closed, repeat closing procedure.
Do not push down on hood to attempt
to fully close it.

Move away from vehicle and do not
open the hood until the engine has
cooled. If necessary, call a fire
department.

Vehicles with gasoline engine:
The engine is equipped with a
transistorized ignition system.
Because of the nigh voltage it is
dangerous to touch any components
(ignition coils, spark plug sockets,
diagnostic socket) of the ignition
system

• with the engine running,

• while starting the engine,

• if ignition is "on" and the engine

is turned manually.

106

Checking Coolant Level

To check the coolant level, the vehicle
must be parked on level ground and
the engine stopped.

Check coolant level only when coolant
is cold.

Adding Coolant

If coolant has to be added, a 50/50
mixture of water and MB
anticorrosion/antifreeze should be
added.

The drain plugs for the cooling system
are located on the right side of the
engine block and at the bottom of the
radiator.

Anticorrosion/antifreeze, see
Coolants in Index.

Warning!

In order to avoid possible serious
burns or injury:

• Use extreme caution when

opening the hood if there are any
signs of steam or coolant leaking
from the cooling system, or if the
coolant temperature gauge
indicates that the coolant is
overheated.

• Do not remove pressure cap on

coolant reservoir if engine
temperature is above 194°F (90°C).
Allow engine to cool down before
removing cap. The coolant
reservoir contains hot fluid and is
under pressure.

• Using a rag, slowly open cap

approximately 1/2 turn to relieve
excess pressure. If opened
immediately, scalding hot fluid
and steam will be blown out
under pressure.

• Do not spill antifreeze on hot

engine parts. Antifreeze contains
etnylene glycol which may burn if
it comes into contact with hot
engine parts.

1 Oil dipstick

2 Oil filler cap

The engine oil level can be checked by

either the oil dipstick or via the
cluster.
To check the engine oil level, park

vehicle on level ground, with engine at
normal operational temperature.

Check engine oil level approximately 5
minutes after stopping the engine,
allowing for the oil to return to the oil
pan.

Oil Dipstick

Wipe oil dipstick clean prior to
checking the engine oil level. Fully
insert dipstick in tube, and remove after
three seconds to obtain accurate
reading.

Oil level must be between
the lower (min) and upper
(max) mark of the dipstick.

Fill quantity between upper and lower
dipstick marking level is approximately

2.1 US qt (2.0 l).
Do not overfill the engine. Excessive

oil must be drained or siphoned. It
could cause damage to engine and
catalytic converter not covered by the
Mercedes-Benz Limited Warranty.

For Low engine oil level warning, see

OIL LEVEL AT MINIMUM

Add oil to upper (max) mark of the
dipstick

OIL LEVEL BELOW MINIMUM

Add oil to upper (max) mark of the

dipstick
OIL LEVEL ABOVE MAX
Do not overfill the engine. Excessive
oil must be drained or siphoned. It
could cause damage to engine and
catalytic converter not covered by the
Mercedes-Benz Limited Warranty.

The symbol flashes in the
multifunction indicator if a proper oil
level check cannot be performed.

The oil level check can be repeated

after a short while.
Perform the oil level check with the
dipstick, if it cannot be completed via
the multifunction indicator.
In this case we recommend that you
have the system checked at a
Mercedes-Benz dealer.

Bleeding of Diesel Fuel System
If the engine ran out of fuel, the fuel

system has to be purged of air after
refilling tank.

Turn the electronic key in steering lock
fully to the right and crank engine (for
up to 40 seconds maximum). Only
release key after engine fires evenly.

Automatic Transmission Fluid Level

The transmission has a permanent fill
of automatic transmission fluid.
Regular automatic transmission fluid
level checks and changes are not
required. For this reason the dipstick is
omitted.

If you notice fluid leaks or gear shifting
malfunctions, have your authorized
Mercedes-Benz dealer check the
transmission fluid level.

Vehicle Jack
1 Jack arm

2 Jack base

The vehicle jack is stored behind the
spare wheel.

See illustration for proper storage of jack.
To remove, first remove vehicle tools and
spare wheel. Then open clamp and
remove vehicle jack.

Before storing the jack in the spare wheel
well, the jack arm must be lowered
almost to the base of the jack.

Warning!

The jack is designed exclusively for
jacking up the vehicle at the jack
tubes built into either side of the
vehicle. To help avoid personal
injury, use the jack only to lift the
vehicle during a wheel change. Never
get beneath the vehicle while it is
supported by the jack. Keep hands
and feet away from the area under
the lifted vehicle. Always firmly set
parking brake and block wheels
before raising vehicle with jack.

Do not disengage parking brake
while the vehicle is raised. Be certain
that the jack is always vertical when
in use, especially on hills. Always try
to use the jack on level surface. Be
sure that the jack arm is fully
inserted in the jack tube. Always
lower the vehicle onto sufficient
capacity jackstands before working
under the vehicle.

Wheels

Replace rims or tires with the same
designation, manufacturer and type as
shown on the original part. See your
authorized Mercedes-Benz dealer for
further information.

See your authorized Mercedes-Benz
dealer for information on tested and
recommended rims and tires for
summer and winter operation. They
can also offer advice concerning tire
service and purchase.

111

Tire Replacement

Front tires should be replaced in sets.
Rims and tires must be of the correct
size and type. For dimensions, see
"Technical Data".

We recommend that you break in new
tires for approx. 60 miles (100 km) at
moderate speed.

It is imperative that the wheel
mounting bolts be fastened to a
tightening torque of 80 ft .lb. (110 Nm)
whenever wheels are mounted.

For rim and tire specifications, refer to
"Technical Data"

Warning!

Worn, old tires can cause accidents.
If the tire tread is badly worn, or if
the tires have sustained damage,
replace them.

When replacing rims, use only
genuine Mercedes-Benz wheel bolts
specified for the particular rim
type. Failure to do so can result in
the bolts loosening and possibly an
accident.

Rotating Wheels

The wheels can be rotated according to
the degree of tire wear while retaining
the same direction of travel.

Rotating, however, should be carried
out at the scheduled service intervals,
before the characteristic tire wear
pattern (shoulder wear on front wheels
and tread center wear on rear wheels)
becomes visible, as otherwise the
driving properties deteriorate.

Important!

Unidirectional tires must always be
mounted with arrow on tire sidewall
pointing in direction of vehicle forward
movement.

Notes:
Thoroughly clean the inner side of the

wheels any time you rotate the wheels
or wash the vehicle underside.

The use of retread tires is not
recommended. Retread tires may
adversely affect the handling
characteristics and safety of the vehicle.

Dented or bent rims can cause tire
pressure loss and damage to the tire
beads. For this reason, check rims for
damage at regular intervals. The rim
flanges must be checked for wear
before a tire is mounted. Remove burrs,
if any.

Check and ensure proper tire inflation
pressure after rotating the wheels. For
Tire Inflation Pressure refer to Index.

to the wheel being changed.

4. Using the wrench, loosen but do
not yet remove the wheel bolts.

113

5. Remove the protective cover from
the jack support tube opening by
inserting the screwdriver (supplied
in the tool kit) in the opening and
prying it out.

The tube openings are located
directly behind the front wheel
housings and in front of the rear
wheel housings.

6. Insert jack arm fully into the tube
hole up to the stop. Place jack
on firm ground. Position the jack
so that it is always vertical
(plumb-line) as seen from the
side (see arrow), even if the
vehicle is parked on an incline.

7. Jack up the vehicle until the
wheel is clear of the ground.
Never start engine while vehicle
is raised.

8. Unscrew upper-most wheel bolt
and install alignment bolt (1)
supplied in the tool kit. Remove
the remaining bolts. Keep bolt
threads protected from dirt and
sand.

9. Remove wheel. Grip wheel from
the sides. Keep hands from

114

12. Using the wrench, tighten the

five bolts evenly, following the
sequence illustrated, until all
bolts are tight.
Observe a tightening torque of
80 ft.lb. (110 Nm).

13. Ensure proper tire pressure.

10. Clean contact surfaces of

wheel and wheel hub. Install
spare wheel on wheel hub.
Insert wheel bolts and tighten
them slightly.
To avoid paint damage, place

Warning!

Always replace wheel bolts that are

damaged or rusted.

Never apply oil or grease to wheel

bolts.

Damaged wheel hub threads should

be repaired immediately.

Incorrect mounting bolts or
improperly tightened mounting bolts
can cause the wheel to come off. This
could cause an accident. Be sure to
use the correct mounting bolts.

115

Tire Inflation Pressure

A table (see fuel filler flap) lists the tire
inflation pressures specified for
Mercedes-Benz recommended tires as
well as for the varying operating
conditions.

Important!

Tire pressure changes by approx. 1.5
psi (0.1 bar) per 18°F (10°C) of air
temperature change. Keep this in mind
when checking tire pressure inside a
garage - especially in the winter.

Example:
If garage temperature = approx. +68°F

(+20°C) and ambient temperature =
approx. +32°F (0°C) then the adjusted
air pressure = specified air pressure +3
psi (+0.2 bar).

Tire pressures listed for light loads are
minimum values offering high driving
comfort. Increased inflation pressures
for heavy loads produce favorable
handling characteristics with lighter
loads and are perfectly permissible.

The ride of the vehicle, however, will

become somewhat harder.
Tire temperature and pressure

increase with the vehicle speed. Tire
pressure should therefore only be
corrected on cold tires. Correct tire
pressure in warm tires only if pressure
has dropped below the pressure listed
in the table and the respective
operating conditions are taken into
consideration.

An underinflated tire due to a slow
leak (e.g. due to a nail in the tire) may
cause damage such as tread
separation, bulging etc.. Regular tire
pressure checks (including the spare
tire) at intervals of no more than 14
days are therefore essential.

If a tire constantly loses air, it should
be inspected for damage.

Warning!

Do not overinflate tires.
Overinflating tires can result in
sudden deflation (blowout) because
they are more likely to become
punctured or damaged by road
debris, potholes etc.. Follow recom­mended inflation pressures.

Do not overload the tires by
exceeding the specified vehicle
capacity weight (as indicated by the
label on the driver's door latch post).
Overloading the tires can overheat
them, possibly causing a blowout.

Adjusting Headlamp

Correct headlamp adjustment is
extremely important. To check and
readjust a headlamp, follow steps 1
through 7. Please note:

• Low beam adjustments

simultaneously aim the high beam.

• Vehicle should have a normal trunk

load.

• Vertical aim adjustments change

horizontal aim.

1. Park vehicle on level surface approx.

6 inches (152 mm) from a vertical

test screen or wall. The centerline of

the vehicle must be at a 90° angle to

the test screen.

2. Using a "T" square and a carpenter's

level, align and mark a vertical

centerline (8) on the test screen using

the outer reference point (low beam)

as found on each headlamp lens.

As a check, the distance between
centerlines should be 491/4 inches
(1250 mm).

3. Move vehicle on the level

surface 25 feet (7.6 m) straight
back from the wall.

4. Open hood.

5. Vertical headlamp aim

(low beams on):
Turn adjusting screw (2) (coun-

terclockwise to adjust headlamp
downward, clockwise upward) until
bubble in the level (8) is centered
on the "O" mark.
Graduations: 0.18° pitch.

6. Horizontal headlamp aim

(low beams on):
Turn adjusting screw (1)
(counterclockwise to adjust to
the left, clockwise to the right)
until the headlamps (low beam)
illuminate the test screen as
shown. The vertex of the angle
formed in each beam image
should align with the vertical
centerline (11) of each lamp.

The left and right headlamps
must be adjusted individually

7. The "O" on the indicator wheel

(9) should align with projection
(10). If it does not, with a small
screwdriver, pry indicator wheel
up and rotate so that the "O"
aligns with projection (1). Push
down indicator wheel until it
snaps in place.

Graduations: 0.38° pitch.
