Warning!
G
For your protection, drive only with properly
positioned head restraints.
Adjust head restraint so that the head re-
straint supports the back of the head at eye
level. This will reduce the potential for injury
to the head and neck in the event of an ac-
cident or similar situation.
Do not drive the vehicle without the seat
head restraints. Head restraints are intend-
ed to help reduce injuries during an acci-
dent.
Do not interchange head restraints from
front and rear seat.
!When installing the head restraints,
make sure that:
The proper head restraint for each
seat is installed. The bars of the
head restraint designed for the mid-
dle rear seat are of even length and
shorter than those designed for use
on the outer rear seats.
The head restraints engage fully.

296 Controls in detailUseful featuresProgramming tips
If you are having difficulty programming
the integrated remote control, here are
some helpful tips:
Check the frequency of the hand-held
remote control5 (typically located on
the reverse side of the remote). The in-
tegrated remote control is compatible
with radio-frequency devices operating
between 288-399 MHz.
Put a new battery in the hand-held re-
mote control5. This will increase the
likelihood of the hand-held remote con-
trol sending a faster and more accurate
signal to the integrated remote control.
While performing step 3, hold the
hand-held remote control6 at differ-
ent lengths and angles from the signal
transmitter button (2, 3 or4) you
are programming. Attempt varying an-
gles at the distance of 2 to 5 inches
(5 to 12 cm) away or the same angle at
varying distances.
If another hand-held remote control is
available for the same device, try the
programming steps again using that
other hand-held remote control. Make
sure new batteries are in the hand-held
remote control before beginning the
procedure.
Straighten the antenna wire from the
garage door opener assembly. This
may help improve transmitting and/or
receiving signals.iCertain types of garage door openers
are incompatible with the integrated
remote control. If you should experi-
ence further difficulties with program-
ming the integrated remote control,
contact an authorized Mercedes-Benz
Center, or call Mercedes-Benz
Customer Assistance Center (in the
USA only) at 1-800-FOR-MERCedes, or
Customer Service (in Canada) at
1-800-387-0100.
iUSA only:
This device complies with Part 15 of
the FCC Rules. Operation is subject to
the following two conditions:
(1) This device may not cause harmful
interference, and
(2) this device must accept any
interference received, including
interference that may cause
undesired operation.
Any unauthorized modification to this
device could void the user’s authority
to operate the equipment.
308 OperationDriving instructionsRoad salts and chemicals can adversely af-
fect braking efficiency. Increased pedal
force may become necessary to produce
the normal braking effect.
Depressing the brake pedal periodically
when traveling at length on salt-strewn
roads can bring road-salt-impaired braking
efficiency back to normal.
If the vehicle is parked after being driven
on salt-treated roads, the braking efficien-
cy should be tested as soon as possible af-
ter driving is resumed.
For more information, see “Winter driving”
(
page 355).
Standing water
Warning!
G
Make sure not to endanger any other road
users when carrying out these braking ma-
neuvers.
Warning!
G
If the vehicle becomes stuck in snow, make
sure that snow is kept clear of the exhaust
pipe and from around the vehicle with the
engine running. Otherwise, deadly carbon
monoxide (CO) gases may enter vehicle in-
terior resulting in unconsciousness and
death.
To assure sufficient fresh air ventilation,
open a window slightly on the side of the ve-
hicle not facing the wind.Warning!
G
The outside temperature indicator is not de-
signed to serve as an ice-warning device and
is therefore unsuitable for that purpose. In-
dicated temperatures just above the freez-
ing point do not guarantee that the road
surface is free of ice.
!Do not drive through flooded areas or
water of unknown depth. Before driving
through water, determine its depth.
Never accelerate before driving into
water. The bow wave could force water
into the engine and auxiliary equip-
ment, thus damaging them.
If you must drive through standing wa-
ter, drive slowly to prevent water from
entering the passenger compartment
or the engine compartment. Water in
these areas could cause damage to
electrical components or wiring of the
engine or transmission, or could result
in water being ingested by the engine
through the air intake causing severe
internal engine damage. Any such dam-
age is not covered by the
Mercedes-Benz Limited Warranty.

Maintenance
Clearing the maintenance service
indicator message
The maintenance service indicator mes-
sage is automatically cleared
after approximately 10 seconds when
you switch on the ignition or when
reaching the service threshold while
driving
after approximately 30 seconds, once
the suggested maintenance service
term has passedYou can also clear it yourself:
Press the reset button 1 on the left
side of the instrument cluster.
The maintenance service indicator
message is cleared and the standard
display appears in the multifunction
display (
page 155).
iVehicles equipped with FSS PLUS
(Flexible S
ervice S
ystem PLUS) only
(Canada vehicles): The interval be-
tween maintenance services depends
on your driving habits. A gentle driving
style, moderate engine speeds and the
avoidance of short-distance trips will
lengthen the interval between services.
456 Practical hintsJump starting
If the battery is discharged, the engine can
be started with jumper cables and the bat-
tery of another vehicle. Observe the follow-
ing:
Jump starting should only be performed
when the engine and catalytic
converter are cold.
Do not start the engine if the battery is
frozen. Let the battery thaw out first.
Only jump start from batteries with the
same voltage rating (12 V). Jump start-
ing with a more powerful battery could
damage the vehicle’s electrical system,
which will not be covered by the
Mercedes-Benz Limited Warranty.
Use only jumper cables with sufficient
cross-section and insulated terminal
clamps.
Always make sure the jumper cables
are not on or near pulleys, fans or other
parts that move when the engine is
started or running.
Warning!
G
Failure to follow these directions will cause
damage to the electronic components, and
can lead to a battery explosion and severe
injury or death.
Never lean over batteries while connecting
or jump starting, you might get injured.
Battery fluid contains sulfuric acid. Do not
allow this fluid to come in contact with eyes,
skin or clothing. In case it does, immediately
flush affected area with water, and seek
medical help if necessary.
A battery will also produce hydrogen gas,
which is flammable and very explosive. Keep
flames or sparks away from battery, avoid
improper connection of jumper cables,
smoking, etc.
Attempting to jump start a frozen battery
can result in it exploding, causing personal
injury.
Read all instructions before proceeding.
!Jump starting may only be performed
on the designated jump start terminals
located in the engine compartment
(page 457).
Avoid repeated and lengthy starting at-
tempts.
Do not attempt to start the engine us-
ing a battery quick charge unit.
If the engine does not run after several
unsuccessful starting attempts, have it
checked at the nearest authorized
Mercedes-Benz Center.
Excessive unburned fuel generated by
repeated failed starting attempts may
damage the catalytic converter.
Make sure the jumper cables do not
have loose or missing insulation.
Make sure the cable clamps do not
touch any other metal part while the
other end is still attached to a battery.
