± (Canada only)
The yellow engine malfunction
indicator lamp comes on while
driving.
There is a malfunction in:

The fuel management system

The ignition system

The emission control system

Systems which affect emissions
Such malfunctions may result in excessive
emissions values and may switch the engine
to its limp-home (emergency operation)
mode.
Have the vehicle checked as soon as
possible by an authorized
Mercedes-Benz Center.
An on-board diagnostic connector is
used by the service station to link the
vehicle to the shop diagnostics system.
It allows the accurate identification of
system malfunctions through the read-
out of diagnostic trouble codes. It is
located in the front left area of the foot-
well next to the parking brake.
iSome states may by law require you to con-
tact a workshop as soon as the engine malfunc-
tion indicator lamp comes on. Check local
requirements.

Front Passenger
Airbag Enabled
See Operator’s ManualFront passenger front air bag is
activated while driving even
though a child, small individual,
or object below the system’s
weight threshold is on the front
passenger seat, or the front
passenger seat is empty. Ob-
jects on the seat or forces act-
ing on the seat may make the
system sense supplemental
weight.Stop the vehicle in a safe location as soon as possible and check the
front passenger seat for the following:
Apply the parking brake.
Switch off the ignition (page 38).
Open the front passenger door.
Remove child and child restraint from front passenger seat and
properly secure the child in rear seat employing the child restraint
if necessary.
Remove any other items from on and around the front passenger
seat and make sure the storage pocket on the back of the front pas-
senger seat is empty.
Make sure that no objects which apply forces to the seat are
present (e.g. objects such as books, briefcases etc. lodged behind
or around the seat, head restraints pushing against roof etc.). The
system may recognize such forces as supplemental weight and
sense that an occupant on the front passenger seat is of a greater
weight than actually present.
Keep the seat unoccupied, close the front passenger door and turn
on the ignition (
page 38).

Check
Brake Fluid
LevelThere is insufficient brake fluid in the
reservoir.Risk of accident! Stop the vehicle in a
safe location and notify an authorized
Mercedes-Benz Center. Do not add
brake fluid! This will not solve the
problem.
Warning!G
Driving with the messages Check Brake
Fluid Level
displayed can result in an ac-
cident. Have your brake system checked im-
mediately.
Do not add brake fluid before checking the
brake system. Overfilling the brake fluid res-
ervoir can result in spilling brake fluid on hot
engine parts and the brake fluid catching
fire. You can be seriously burned.!If you find that the brake fluid in the brake
fluid reservoir has fallen to the minimum mark or
below, have the brake system checked for brake
pad thickness and leaks.

What to do if …
During severe operation conditions and
stop-and-go city traffic, the coolant tem-
perature may rise close to 248°F (120°C).
Display symbolDisplay messagePossible cause/consequencePossible solution
DCoolant
Stop Vehicle,
turn engine off.The coolant is too hot.Stop the vehicle in a safe location or as soon
as it is safe to do so and immediately turn
off the engine.
Only start the engine again after the mes-
sage disappears. You could otherwise dam-
age the engine.
Apply the parking brake (page 53).
Observe the coolant temperature indicator
in the instrument cluster (
page 26).
If the temperature rises again:
Contact an authorized Mercedes-Benz
Center immediately.
Warning!G
Driving when your engine is badly overheat-
ed 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.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of
the vehicle and do not stand near the vehicle
until the engine has cooled down.
!The engine should not be operated with the
coolant temperature above 248°F (120°C).
Doing so may cause serious damage which is not
covered by the Mercedes-Benz Limited
Warranty.

Where will I find...?
Vehicle jackThe vehicle jack is located in the storage
compartment underneath the trunk floor.
Storage position
Remove vehicle jack from its
compartment.
Turn crank handle in direction of arrow
as far as it will go.
Operational position
Turn crank handle clockwise.
Before storing the vehicle jack in its com-
partment:

It should be fully collapsed.

The handle must be folded in (storage
position).
Warning!G
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into both sides 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 (plumb line) when in use, es-
pecially on hills. Always try to use the jack
on a level surface. Make sure the jack arm is
fully seated in the jack take-up bracket.
Always lower the vehicle onto sufficient
capacity jackstands before working under
the vehicle.

Replacing bulbs
Rear lamps Notes on bulb replacement

Use only 12 volt bulbs of the same type
and with the specified watt rating.

Switch lights off before changing a bulb
to prevent short circuits.

Always use a clean lint-free cloth when
handling bulbs.

Your hands should be dry and free of oil
and grease.

If the newly installed bulb does not light
up, contact an authorized
Mercedes-Benz Center.

Warning!G
Bulbs and bulb sockets can be very hot. Al-
low the lamp to cool down before changing
a bulb.
Keep bulbs out of reach of children.
Halogen lamps contain pressurized gas. A
bulb can explode if you:

touch or move it when hot

drop the bulb

scratch the bulb
Wear eye and hand protection.
Because of high voltage in Xenon lamps, it is
dangerous to replace the bulb or repair the
lamp and its components. We recommend
that you have such work done by a qualified
technician.

Replacing bulbs
Have the LEDs and bulbs for the following
lamps replaced by an authorized
Mercedes-Benz Center:

Additional turn signals in the exterior

6Bulb holder of low beam bulb
Before you start to replace a bulb for a
front lamp, do the following first:
Turn the exterior lamp switch to
positionM (
page 126).
Open the hood (page 286) (except
for side marker lamps).
!Do not replace the LEDs yourself. You could
otherwise damage the LEDs or parts of the vehi-
cle. Only have the LEDs replaced by an autho-
rized Mercedes-Benz Center.
Warning!G
Do not remove the cover1 for the Bi-Xe-
non* headlamp. Because of high voltage in
Xenon* lamps, it is dangerous to replace the
bulb or repair the lamp and its components.

Flat tire
Preparing the vehicle
Park the vehicle in a safe distance from
moving traffic on a hard, flat surface
when possible.
Turn on the hazard warning flashers.
Turn the steering wheel so that the
front wheels are in a straight ahead
position.
Set the parking brake.
Move the gear selector lever toP.
Turn off the engine (page 60).
Have any passenger exit the vehicle at
a safe distance from the roadway.
Vehicles with SmartKey: Remove the
SmartKey from the starter switch.
Vehicles with KEYLESS-GO*: Open the
driver’s door (this puts the starter
switch in position 0, same as with the
SmartKey removed from the starter
switch). The driver’s door then can be
closed again.
Mounting the spare wheel
iOpen door only when conditions are safe to
do so.
Warning!G
The dimensions of the spare wheel
(Minispare or collapsible tire) are different
from those of the road wheels. As a result,
the vehicle handling characteristics change
when driving with a spare wheel mounted.
Adapt your driving style accordingly.
The spare wheel is for temporary use only.
When driving with spare wheel mounted,
ensure proper tire pressure and do not ex-
ceed a vehicle speed of 50 mph (80 km/h).
Drive to the nearest Mercedes-Benz Center
as soon as possible to have the spare wheel
replaced with a regular road wheel.
Never operate the vehicle with more than
one spare wheel mounted.
Do not switch off the ESP
® when a Minis-
pare or collapsible tire is mounted.
