Memory function
Memory function
You can store up to three different settings
per key.
The following settings are saved for each
stored position:
Driver’s seat and backrest position
Steering wheel position
Driver’s side exterior rear view mirror
position
Passenger side exterior rear view mir-
ror position
Front passenger seat position
These key-dependent memory settings
can be deactivated if desired
(
page 110).
!Prior to operating the vehicle, the driv-
er should check and adjust the seat
height, seat position fore and aft, and
backrest angle if necessary, to ensure
adequate control, reach and comfort.
The head restraint should also be ad-
justed for proper height. Also see the
section on airbags (
page 57) for
more information on proper seat posi-
tioning.
In addition, adjust the steering wheel to
ensure adequate control, reach, opera-
tion and comfort. Both the inside and
outside rear view mirrors should be ad-
justed for adequate rear vision.
Fasten seat belts. Infants and small
children should be seated in a properly
secured restraint system that complies
with U.S. Federal Motor Vehicle Safety
Standard 213 and Canadian Motor Ve-
hicle Safety Standard 213.
Warning!

Warning!
G
When closing the panorama sliding/pop-up
roof, ensure that no one is in danger of being
injured.
If the panorama sliding/pop-up roof is
closed with the convenience closing feature
and becomes blocked, it will not open auto-
matically.
Should this occur, press the release button
on the key and hold it down; the panorama
sliding/pop-up roof opens again.
Make sure to remove the key from the igni-
tion lock even when leaving the vehicle for
only a brief period of time.
In the event of an accident, the glass in ve-
hicles with a glass roof may shatter.
If the vehicle rolls over, there is a danger of
occupants without fastened seat belts being
thrown out of the opening.
In this case there is an increased risk of in-
jury even for passengers with fastened seat
belts, as entire body parts or portions of
them may protrude from the passenger
compartment.

282 OperationVehicle careEngine cleaning
Prior to cleaning the engine compartment,
make sure to protect electrical compo-
nents and connectors from contact with
water and cleaning agents.
Corrosion protection, such as MB Anticor-
rosion Wax should be applied to the engine
compartment after every engine cleaning.
Before applying, all control linkage bush-
ings and joints should be lubricated. The
poly-V-belt and all pulleys should be pro-
tected from any wax.
Vehicle washing
Do not use hot water or wash your vehicle
in direct sunlight. Use only a mild car wash
detergent, such as Mercedes-Benz ap-
proved Car Shampoo.
Thoroughly spray the vehicle with a dif-
fused jet of water. Direct only a very weak
spray towards the ventilation intake. Use
plenty of water and rinse the sponge and
chamois frequently. Rinse with clear water and thoroughly wipe
dry with a chamois. Do not allow cleaning
agents to dry on the finish.
Due to the width of the vehicle, fold in out-
side mirrors prior to running the vehicle
through an automatic car wash to prevent
damage to the mirrors.
In the winter, thoroughly remove all traces
of road salt as soon as possible.
When washing the undercarriage, do not
forget to clean the inner sides of the
wheels.Ornamental moldings
For regular cleaning and care of very dirty
chrome-plated parts, use a chrome clean-
er.
Headlamps, tail lamps, turn signal
lenses
Use a mild car wash detergent, such as
Mercedes-Benz approved Car Shampoo,
with plenty of water.
To prevent scratches, never apply strong
force and use only a soft, non-scratchy
cloth when cleaning the lenses. Do not at-
tempt to wipe dirty lenses with a dry cloth
or sponge.
iVehicles with KEYLESS-GO*:
If a door handle is hit by a strong jet of
water, and a SmartKey with KEY-
LESS-GO* is in close proximity, i.e.
within approx. 3 ft. (approx. 1 m), the
vehicle could be inadvertently locked
or unlocked.

Seat belts
The webbing must not be treated with
chemical cleaning agents. Use only clear,
lukewarm water and soap. Do not dry the
webbing at temperatures above 176°F
(80°C) or in direct sunlight.Leather upholstery
Using aftermarket seat covers or wearing
clothing that have the tendency to give off
coloring (e.g. when wet, etc.) may cause
the upholstery to become permanently dis-
colored. By lining the seats with a proper
intermediate cover, contact-discoloration
will be prevented.
Wipe leather upholstery with a damp cloth
and dry thoroughly or clean with
Mercedes-Benz approved Leather Care.
Exercise particular care when cleaning per-
forated leather as its underside should not
become wet.
MB Tex upholstery
Pour Mercedes-Benz approved Interior
Care onto a soft, lint-free cloth and apply

severely weaken them. In a crash they may
not be able to provide adequate protection.

Problem
Possible cause
Suggested solution
?
The yellow "CHECK ENGINE"
malfunction indicator lamp
comes on while driving.
There is a malfunction in:
The fuel injection system
The ignition system
The exhaust system
The fuel system
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 sys-
tem. It allows the accurate identifica-
tion of system malfunctions through
the readout of diagnostic trouble
codes. It is located in the front left
area of the footwell next to the park-
ing brake.
Your gas tank is empty.
After refuelling, start the engine three
or four times in succession.
The limp-home mode is canceled. You do
not need to have your vehicle checked.
<
The red seat belt warning lamp
blinks for a brief period after
starting the engine.
The warning lamp reminds you to fasten seat
belts.
Fasten your seat belt.

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.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until it
cools down. The engine should not be oper-
ated with the coolant temperature above
266°F (130°C). Doing so may cause serious
engine damage which is not covered by the
Mercedes-Benz Limited Warranty.
