Malfunction and indicator lamps
in the instrument cluster
General information:
If a bulb in the instrument cluster fails to light up
during the bulb self-check when turning the key in
steering lock to position 2, have it checked and replaced
if necessary.
On-board diagnostic system
Check engine malfunction indicator lamp
Engine malfunction indicator lamp. If the
“CHECK ENGINE” malfunction indicator
lamp comes on when the engine is running,
it indicates a malfunction of the fuel management
system, emission control system, systems which impact
emissions, or the fuel cap is not closed tight (check the
fuel cap). If the “CHECK ENGINE” lamp is illuminated
continuously and the vehicle is driving normally, you
may still drive the vehicle, however, in all cases, we
recommend that you have the system checked at your
authorized Mercedes-Benz Center as soon as possible. If the “CHECK ENGINE” lamp comes on continuously
and / or the vehicle is not driving normally, serious
damage can occur to the emission system. Please
contact your authorized Mercedes-Benz Center
immediately.
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 SFI control module.
If the “CHECK ENGINE” malfunction indicator lamp
comes on, have the system checked at your authorized
Mercedes-Benz Center 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. See also page 181 for
fuel cap placement warning.

cluster displayPractical hints Car care Index Fuel reserve and fuel cap placement warning
With the key in steering lock position 2, the fuel reserve
warning lamp comes on. It should go out immediately
when the engine is running.
If the warning lamp does not go out 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 2.1 gal (8 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 warning lamp goes out after
restart and next OBD selfcheck.
If the warning lamp continues to blink after closing the
fuel cap correctly, have the fuel system checked at your
authorized Mercedes-Benz Center as soon as possible.
Leaving the engine running and the fuel cap open can
a lso c ause t he “CH ECK ENG INE” lamp to ill uminate, see
also page 178.Electronic stability program (ESP) — warning lamp
The yellow ESP warning lamp in the
speedometer dial comes on with the key in
steering lock position 2. It should go out
with engine running.
See page 170 if the warning lamp lights up or f lashes
when the vehicle is moving.
BAS / ESP malfunction indicator lamp
The malfunction indicator lamp for the ESP
is combined with that of the BAS.
The yellow BAS / ESP malfunction indicator
lamp in the instrument cluster comes on with the key in
steering lock position 2. It shoul d go out w it h th e engine
running.
If the BAS / ESP malfunction indicator lamp comes on
continuously with the engine running, see page 166
and 170.

Low engine oil level warning lamp
With the key in steering lock position 2, the
oil level warning lamp comes on. It should
go out immediately when the engine is
running.
If the warning lamp does not go out after starting the
engine, or comes on with the engine running and at
operating temperature, the engine oil level has dropped
to approximately the minimum mark on the dipstick.
When this occurs, the warning lamp will first come on
intermittently and then stay on if the oil level drops
further.
If no 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 light should not be
ignored. Extended driving with the light illuminated
could result in serious engine damage that is not
covered by the Mercedes-Benz Limited Warranty.
In addition to the warning lamp, the engine oil level
should be periodically checked with the dipstick, for
example during a fuel stop, or before a long trip, see
page 193.Charge indicator lamp
Should the charge indicator lamp fail to
come on prior to starting when the key is in
ste ering lock position 2 or sh ou ld it fa il to g o
out after starting or during operation, this indicates a
malfunction which must be repaired immediately at an
authorized Mercedes-Benz Center.
If t he charg e ind ica tor l amp comes on, or a l oss of power
steering assistance is noticeable while the engine is
running, this may indicate that one of the two poly-V-
belts has broken. Should this condition occur, the poly-
V-belt mu st be replac ed before continuing to operate t he
vehicle. Otherwise, the engine may 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 lamp illuminated. Doing so could result in
serious engine damage that is not covered by the
Mercedes-Benz Limited Warranty.

cluster displayPractical hintsCar care Index Tire inflation pressure
A table (see fuel filler f lap) lists the tire inflation
pressures specified for Mercedes-Benz recommended
tires as well as for the varying operating conditions.
Important!
Tire pressure changes by approximately 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 = approximately +68°F (+20°C)
and ambient temperature = approximately +32°F (0°C)
then the adjusted air pressure = specified air pressure
+3psi (+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 checked
and 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 underinf lated 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 at
intervals of no more than 14 days are therefore
essential.
213 Jump starting
Te ch n ica l
data Instruments
and controlsOperation DrivingInstrument
cluster displayPractical hintsCar care Index Proceed as follows:
1.Position the vehicle with the charged battery so that
the jumper cables will reach, but never let the
vehicles touch. Make sure the jumper cables do not
have loose or missing insulation.
2.On both vehicles:
•Turn off engine and all lights and accessories,
except hazard warning flashers or work lights.
•Apply parking brake and shift selector lever to
position “P” (manual transmission to Neutral).
Important!
3.Clamp one end of the first jumper cable to the
positive (+) terminal of the discharged battery and
the other end to the positive (+) terminal of the
charged battery. Make sure the cable clamps do not
touch any other metal parts.
4.Clamp one end of the second jumper cable to the
grounded negative (–) terminal of the charged
battery and the final connection to a grounded
heavy metal bracket in the engine compartment or
on the engine of the disabled vehicle.Important!
5.Start engine of the vehicle with the charged battery
and run at high idle. Make sure the cables are not
on or near pulleys, fans, or other parts that will
move when the engine is started. Allow the
discharged battery to charge for a few minutes. Start
engine of the disabled vehicle in the usual manner.
6.After the engine has started, remove jumper cables
by exactly reversing the above installation
sequence, starting with the last connection made
first. When removing each clamp, make sure that it
does not touch any other metal while the other end
is still attached.
Note:
If engine does not run after several unsuccessful
starting attempts, have it checked at the nearest
authorized Mercedes-Benz Center.
Excessive unburned fuel may damage the catalytic
converter.

Do not allow the wiper arms to contact the windshield
glass without a wiper blade inserted. The glass may be
scratched or broken.
Make certain that the wiper blade is properly installed.
An improperly installed wiper blade may cause
windshield damage.
Antenna
To prevent damage or diminished radio reception after
reinstallation, the non-retractable antenna should not
be removed. The antenna is automatic car-wash safe.Manual release of fuel filler flap
The manual release knob is located behind cover (1) in
the right slide trunk panel.

Cleaning and care of the vehicle
In operation, your vehicle is subjected to varying
external inf luences which, if gone unchecked, can
attack the paintwork as well as the underbody and
cause lasting damage.
Such damage is caused not only by extreme and varying
climatic conditions, but also by air polution, road salt,
tar, gravel and stone chipping. Grease and oil, fuel,
coolant, brake fluid, bird droppings, insects, tree resins
etc. should be removed immediately to avoid paint
damage. Frequent washing reduces and/or eliminates
the aggressiveness and potency of the above adverse
influences.More frequent washings are necessary to deal with
unfavorable conditions; for example, near the ocean, in
industrial areas (smoke, exhaust emissions), or during
winter operation.
You should check your vehicle from time to time for
stone chipping or other damage. Any damage should be
repaired as soon as possible to prevent the start of
corrosion.
In doing so, do not neglect the underside of the vehicle.
A prerequisite for a thorough check is a washing of the
underbody followed by a thorough inspection. Damaged
areas need to be reundercoated.
Your vehicle has been treated at the factory with a wax-
base ru stproof ing in th e body cavities w hich will la st for
the lifetime of the vehicle. Post-production treatment is
neither necessary nor recommended by Mercedes-Benz
because of the possibility of incompatibility between
materials used in the production process and others
applied later.
We have selected car-care products and compiled
recommendations which are specially matched to our
vehicles and which always reflect the latest technology.
You can obtain Mercedes-Benz approved car-care
products at your authorized Mercedes-Benz Center.
Wa r n i n g !
Many cleaning products can be hazardous. Some
are poisonous, others are flammable. Always follow
the instructions on the particular container.
Always open your vehicle’s doors or windows when
cleaning the inside.Never use fluids or solvents that are not designed
for cleaning your vehicle.
