Mercedes-Benz E-class 1999 Control Switch
ASR Control Switch
ASR control switch located on center
console
To improve the vehicle's traction when
driving with snow chains, or starting
off in deep snow, sand or gravel, press
the upper half of the ASR switch. The
ASR warning lamp, located in the
speedometer dial, is continuously
illuminated.
With the ASR system switched off, the
engine torque reduction feature is
cancelled. Therefore, the enhanced
vehicle stability offered by ASR is
unavailable.
Adapt your speed and driving to the
prevailing road conditions.
A portion of the ASR system remains
active, even with the switch in the OFF
position.
If one drive wheel loses traction and
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.
The ASR 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.
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.
101
Electronic Stability Program
(ESP) (optional)
(standard on E 430 and E 55 AMG;
optional on E 300 TD and E 320)
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
0 or 1). Otherwise, the ESP will
immediately be engaged and will apply
the rear wheel brakes.
Notes:
The indicator lamp for the ESP is
combined with that of the BAS.
The yellow BAS/ESP malfunction
indicator lamp in the instrument cluster
and the yellow ESP 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.
If the BAS/ESP malfunction indicator
lamp comes on permanently 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 ESP checked at your
authorized Mercedes-Benz dealer as
soon as possible.
With the ABS malfunctioning, the ESP
is also switched off.
Driving the vehicle with varied size
tires will cause the wheels to rotate at
different speeds, therefore the
electronic stability program may
activate (yellow ESP 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
electronic stability program will
immediately be engaged and will
apply the rear wheel brakes.
In winter operation, the maximum
effectiveness of the electronic stability
program is only achieved with
Mercedes-Benz recommended M+S
rated radial-ply tires and/or snow
chains.
Synchronizing ESP
If the power supply was interrupted
(battery disconnected or empty), the
BAS/ESP malfunction indicator lamp
may be illuminated with the engine
running.
Turn steering wheel completely to the
left and then to the right. The BAS/ESP
malfunction indicator lamp should go
out

103
Emission Control
Warning!
Vehicles with gasoline engine
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 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
Whenthe"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.
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"CHECKENGINE" 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.
104
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.
105
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 E 430 with Sport Package
Use only the MB authorized special
snow chain with tire size 235/45 R 17
93 W.

Practical Hints
107
Hood
pull
To open:
Pull handle (2) completely out of
radiator grill and open hood (do not
up on handle).
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.
Move away from vehicle and do not
open the hood until the engine has
cooled. If necessary, call a fire
department.
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.
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.
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.
108
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).
Allowengine 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.

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.
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.
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.

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.
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

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.
113
Tire Replacement
Warning!
Important!
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"
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
Rotation of wheels does not apply to
model E 55 AMG with summer tires.
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.
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.
114
Spare Wheel
Warning!
Warning!
(except E 430 with Sport Package and
E 55 AMG)
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:
• Drive to the nearest tire repair facility
as soon as possible.
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.

safe distance from the roadway.
1. Set parking brake and turn on
hazard warning flasher.
2. Move selector lever to position
"P" and turn off engine.
Prevent vehicle from rolling
away by blocking wheels with
wheel chocks (not supplied with
vehicle) or sizable wood block
or stone. When changing a
wheel on a hill, place chocks on
the downhill side blocking both
wheels of the other axle. On a level
road, place one chock in front of
and one behind the wheel that is
diagonally opposite to the wheel
being changed.
4. Using the wrench, loosen but do
not yet remove the wheel bolts.
5. Remove the protective cover
from the jack support tube
opening by inserting the screw
driver (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.
117
9. Remove wheel. Grip wheel from
the sides. Keep hands from beneath
the wheels.
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
wheel flat against hub and hold it
there while installing first wheel bolt.
Unscrew the alignment bolt (1) to
install the last wheel bolt.
11. Lower car. Remove jack and
insert jack tube cover.
Before storing the jack, the jack
arm must be lowered almost to the
base of the jack.
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!
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.
118
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.

touch glass portion of bulb with bare
hands. Use plain paper or a clean cloth.
Warning!
Halogen lamps contain pressurized
gas. A bulb can explode if you:

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 491/4inches
(1250 mm).
3. Open hood.
4. Vertical headlamp aim
(low beams on):
Turn adjusting screw (2) (counterclockwise to adjust headlamp
downward, clockwise upward) until
bubble in the level (8) is centered
on the "O" mark.
Graduations: 0.18° pitch.
