Mercedes-Benz E 320 Wagon 1999 User Manual
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.
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.
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.
Have the BAS, ASR or ESP checked at
your authorized Mercedes-Benz dealer
as soon as possible.
101
Electronic Traction System (ETS)
(Model with All Wheel Drive
[AWD]: 4-ETS)
The ETS improves vehicle 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 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 dynamometer,
the engine must be shut off (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 radial-ply tires
and/or snow chains.
102
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 in acceleration.
While engaged, the yellow warning
lamp in the speedometer dial flashes.
With the ASR engaged, the brake is
applied to the spinning drive wheel
until slip is brought under control. If
both drive wheels 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, thus allowing acceleration
without slip, 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 ASR will
immediately be engaged and will apply
the rear wheel brakes.
Notes:
The malfunction indicator lamp for the
ASR is combined with that of the BAS.
The yellow BAS/ASR malfunction
indicator lamp in the instrument cluster
and the yellow ASR warning lamp in
the speedometer dial come on with the

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 ASR
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 ASR
will immediately be engaged and will
apply the rear wheel brakes.
In winter operation, the maximum
effectiveness of the ASR is only
achieved with Mercedes-Benz
recommended M+S rated radial-ply
tires and/or snow chains.

begins to spin, the brake is applied
until the wheel regains sufficient
traction. The traction control engages
at vehicle speeds up to approximately
24 mph (40 km/h), and switches off at
50 mph (80 km/h).
Note:
Avoid spinning of one drive wheel.
Doing so may cause serious damage to
the drive train which is not covered by
the Mercedes-Benz Limited Warranty.

speedometer dial, starts to flash at any
vehicle speed as soon as the tires lose
traction and the wheels begin to spin.
To return to the enhanced vehicle
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.
104
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
axle raised (see Towing the vehicle in
Index), the engine must be shut off
(electronic key in steering lock position

Warning!
On-Board Diagnostic System
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.
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
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.
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.
With some exceptions, the control
module switches off the "CHECK
ENGINE" malfunction indicator lamp if
the condition, causing the lamp to come
on, no longer exists during three
consecutive cycles
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.
107
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.
• 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.
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.
• 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.
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.
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
109
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
pull upon 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.
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.
The engine is equipped with a
transistorized ignition system.
Because of the high 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.
If you see flames, steam or smoke
coming from the engine
compartment, or if the coolant
temperature gauge indicates that the
engine is overheated, do not open the
hood. Move away from vehicle and
do not open the hood until the engine
has cooled. If necessary, call a fire
department.
110
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.
• 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
approximately1/2turn to relieve
excess pressure. If opened
immediately, scalding hot fluid
and steam will be blown out
under pressure.
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.
The coolant level should reach the
black top part of the reservoir.
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 spill antifreeze on hot
engine parts. Antifreeze contains
etnylene glycol which may burn if
it comes into contact with hot
engine parts.

112
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 engine oil level check can be
repeated after a short while.
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.
OIL LEVEL AT MINIMUM
A signal sounds. Add oil to upper
(max) mark of the dipstick (also see
Low engine oil level warning in
Index).
OIL LEVEL BELOW MINIMUM
A signal sounds. Add oil to upper
(max) mark of the dipstick (also see
Low engine oil level warning in
Index).
OIL LEVEL ABOVE MAX
A signal sounds.
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.
Perform the engine 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.
Notes:
If the message is continuously
displayed after pressing button 0 twice
and there is no change in the
multifunction indicator or the low engine
oil level warning comes on, a
malfunction has occurered to the
system. Perform the engine oil level
check with the dipstick.
If no oil leaks are noted continue to
drive to the nearest Mercedes-Benz
dealer to have the system checked.
If you notice fluid leaks or gear shifting
malfunctions, have your authorized
Mercedes-Benz dealer check the
transmission fluid level.

Warning!
Wheels
Tire Replacement
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.
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.
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.
115
Rotating Wheels
Drive to the nearest tire repair facility
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.
Spare Wheel
Important!
The spare wheel rim is mounted with a
full size tire of the same type as on the
vehicle, and is fully functional.
However, that spare wheel rim is
weight optimized and has a limited
service life of 12 000 miles (20 000
km) use before a standard wheel rim
must replace it.
In the case of a flat tire, you may
temporarily use the spare wheel.
Do not operate vehicle with more than
one spare wheel mounted.
Unidirectional tires must always be
mounted with arrow on tire sidewall
pointing in direction of vehicle forward
movement.
If the arrow on tire side wall does not
point in direction of vehicle forward
movement when using the spare wheel,
observe the following restrictions:
as soon as possible.
For rim and tire specifications, refer to
"Technical Data".
Warning!
The spare wheel rim is for
temporary use only. Use for over a
total of 12 000 miles (20 000 km) may
cause wheel rim failure leading to an
accident and possible injuries.

Before storing the jack, the jack arm
must be lowered almost to the base of
the jack.
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.
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.
Warning!
The spare wheel rim is for
temporary use only. Use for over a
total of 12 000 miles (20 000 km)
may cause wheel rim failure leading
to an accident and possible injuries.

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.
