402 Practical hintsReplacing bulbs
Notes on bulb replacement

Only use 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
come on, visit an authorized
Mercedes-Benz Center.Have the LEDs and bulbs for the following
lamps replaced by an authorized
Mercedes-Benz Center:


Additional turn signal lamps in the
exterior rear view mirrors


Bi-Xenon* lamps


Front fog lamps


High mounted brake lamp


Brake lamps


Front and rear side marker lamps


Parking/standing lamps in the tail
lamp assemblies
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.
iHave the headlamp adjustment
checked regularly.

1Wheel wrench
On wheel to be changed, loosen but do
not yet remove the wheel bolts in direc-
tion of arrow (approximately one full
turn with wheel wrench1).
The jack take-up brackets are located di-
rectly behind the front wheel housings and
in front of the rear wheel housings.2Jack
3Take-up bracket

Place jack2 on firm ground.

Position jack2 under take-up
bracket3 so that it is always vertical
(plumb-line) as seen from the side,
even if the vehicle is parked on an
incline.
Warning!
G
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
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 (plumb line) when in use, es-
pecially on hills. Always try to use the jack
o n l e v e l s u r f a c e . B e s u r e t h e j a c k a r m i s f u l l y

lower the vehicle onto sufficient capacity
jackstands before working under the
vehicle.
Warning!
G
Position the jack only on the jack take-up
brackets designed for this purpose.
If the jack is not properly positioned, the ve-
hicle may fall off of the jack.

416 Practical hintsFlat tire
Clean contact surfaces of wheel and
wheel hub.

Guide the spare wheel onto the align-
ment bolt and push it on.

Insert the wheel bolts and tighten them
slightly.
!Wheel bolts2 must be used when
mounting the spare wheel with
collapsible tire. The use of any wheel
bolts other than wheel bolts2 for the
spare wheel with collapsible tire will
physically damage the vehicle’s
brakes. !To avoid paint damage, place wheel flat
against hub and hold it there while in-
stalling first wheel bolt.
Warning!
G
Always replace wheel bolts that are dam-
aged or rusted.
Never apply oil or grease to wheel bolts.
Damaged wheel hub threads should be re-
paired immediately. Do not continue to drive
under these circumstances! Contact an au-
thorized Mercedes-Benz Center or call
Roadside Assistance.
Incorrect wheel bolts or improperly tight-
ened wheel bolts can cause the wheel to
come off. This could cause an accident. Be
sure to use the correct wheel bolts.

iVehicles with automatic transmission*:
Do not tow-start vehicle.

426 Practical hintsTowing the vehicleMercedes-Benz recommends that the vehi-
cle be transported with all wheels off the
ground using flatbed or appropriate wheel
lift/dolly equipment.When circumstances do not permit the
recommended towing methods, the vehi-
cle may be towed with all wheels on the
ground or front wheels raised only so far as
necessary to have the vehicle moved to a
safe location where the recommended
towing methods can be employed.
!Vehicles with automatic transmission*:
Do not tow-start vehicle.!Use flatbed or wheel lift/dolly equip-
ment with the SmartKey in the starter
switch in position0.
Do not tow with sling-type equipment.
Towing with sling-type equipment over
bumpy roads will damage radiator and
supports.
To prevent damage during transport,
do not tie down vehicle by its chassis or
suspension parts.
Switch off the tow-away alarm
(page 88) and the automatic central
locking (
page 101).
!To be certain to avoid a possibility of
damage to the transmission, however,
we recommend the drive shaft be dis-
connected at the rear axle drive flange
for any towing beyond a short tow to a
nearby garage.
!If the vehicle is towed with the front
axle raised, the engine must be shut off
(SmartKey in starter switch
position0or1). Otherwise, the ESP
®
will immediately be engaged and will
apply the rear wheel brakes.
When towing the vehicle with all wheels
on the ground, the gear selector lever*
must be in positionN (manual trans-
mission: gear shift lever in neutral posi-
tion) and the SmartKey must be in
starter switch position1.
When towing the vehicle with all wheels
on the ground or the front axle raised,
the vehicle may be towed only for dis-
tances up to 30 miles (50 km) and at a
speed not to exceed 30 mph
(50 km/h).

427 Practical hints
Towing the vehicle
Warning!
G
If circumstances require towing the vehicle
with all wheels on the ground, always tow
with a tow bar if:

the engine will not run


there is a malfunction in the power sup-
ply or in the vehicle’s electrical system
as that will be necessary to adequately con-
trol the towed vehicle.
Prior to towing the vehicle with all wheels on
the ground, make sure the SmartKey is in
starter switch position2.
If the SmartKey is left in starter switch
position0 for an extended period of time, it
can no longer be turned in the switch. In this
case, the steering is locked. To unlock, re-
move SmartKey from starter switch and re-
insert.
Warning!
G
With the engine not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the ve-
hicle. Adapt your driving accordingly.iTo signal turns while being towed with
the hazard warning flasher in use,
switch on ignition and activate the
combination switch for the left or right
turn signal in the usual manner – only
the selected turn signal will operate.
Upon canceling the turn signal, the haz-
ard warning flasher will operate again.
!When towing the vehicle with all wheels
on the ground, please note the follow-
ing:
With the automatic central locking acti-
vated and the SmartKey in starter
switch position2, the vehicle doors
lock if the left front wheel as well as the
right rear wheel are turning at vehicle
speeds of approx. 9 mph (15 km/h) or
more.
To prevent the vehicle door locks from
locking, deactivate the automatic cen-
tral locking (
page 101).
Switch off the tow-away alarm
(
page 88).
The vehicle should only be towed using
a properly installed towing eye bolt.
Never attach a tow cable, tow rope or
tow rod to the vehicle chassis, frame or
suspension parts.
