Removing the wheelGWarning!
When jacking up the vehicle, only use the jack
which has been specifically approved by
Mercedes-Benz for your vehicle.
The jack is designed exclusively for jacking up
the vehicle at the jack take-up brackets built
into both sides of the vehicle. Make sure the
jack arm is fully seated in the jack take-up
bracket. The jack must always be vertical
when in use, especially on inclines or
declines.
The jack is intended only for lifting the vehicle
briefly for wheel changes. It is not suited for
performing maintenance work under 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 lower the vehicle onto sufficient
capacity jackstands before working under the
vehicle.
Always make sure the electronic parking
brake is engaged. In addition, block the
wheels with wheel chocks or other sizeable
objects before raising the vehicle with the
jack. Do not disengage the electronic parking
brake while the vehicle is raised.
Make sure that the ground on which the
vehicle is standing and where you place the
jack is solid, level and not slippery. If
necessary, use a large underlay. On slippery
surfaces, such as tiled floors, you should use
a non-slip underlay, for example a rubber mat.
Do not use wooden blocks or similar objects
to support the jack. Otherwise the jack may
not be able to achieve its load-bearing
capacity if it is not at its full height.
Never start the engine when the vehicle is
raised.
Also observe the notes on the jack.
XOn the wheel to be changed, loosen but do
not yet remove the wheel bolts
(approximately one full turn with wheel
wrench :).
XAssemble the jack (Y page 363).
The jack take-up bracket is located centrally
between the front and rear wheel housings
where indicated by the arrow.
GWarning!
The jack is designed exclusively for jacking up
the vehicle at the jack take-up brackets. Make
sure the jack arm is fully seated in the jack
take-up bracket.
If you do not position the jack correctly in the
jack take-up bracket, the vehicle can fall off
the jack and seriously or fatally injure you or
others.
! Do not position the jack on the body of
the vehicle, as this may cause damage to
the vehicle.

Mounting the wheel
GWarning!
Always replace wheel bolts that are damaged
or rusted.
Never apply oil or grease to wheel bolts.
Damaged wheel hub threads should be
repaired immediately. Do not continue to
drive under these circumstances! Contact an
authorized Mercedes-Benz Center or call
Roadside Assistance.
Incorrect wheel bolts or improperly tightened
wheel bolts can cause the wheel to come off.
This could cause an accident. Make sure to
use the correct wheel bolts.
GWarning!
Only use genuine Mercedes-Benz wheel bolts.
Other wheel bolts may come loose.
Do not tighten the wheel bolts when the
vehicle is raised. Otherwise the vehicle could
fall off the jack.

torque of 96 lb-ft (130 Nm).
GWarning!
Have the tightening torque checked after
changing a wheel. The wheels could come
loose if they are not tightened to a torque of
96 lb-ft (130 Nm).
XFully collapse the jack, with handle folded

Do not rub the battery with rags or cloths. The
battery could explode if touched due to
electrostatic charge or due to spark
formation.
! The battery is a Valve-Regulated Lead
Acid (VRLA) battery, also referred to as
“fleece” battery.
Such batteries do not require topping-up of
the electrolyte level. VRLA batteries
therefore do not have cell caps and the
battery cover is non-removable. Do not
attempt to open the battery as otherwise
the battery will be damaged.
VRLA batteries do not require topping-up of
the electrolyte level. They cannot be
opened to check the electrolyte level.
However, the battery condition must be
checked periodically by performing a
battery conductance test. Refer to
Maintenance Booklet for battery condition
testing intervals.
The factory-equipped battery may only be
replaced with a battery that
Rhas the same security features
Ris of identical size
Ris of identical voltage
Ris of identical capacity
! As any other battery, the battery may
discharge if you do not operate the vehicle
for an extended period of time. Have the
battery disconnected at a qualified
workshop or an authorized Mercedes-Benz
Center in such a case. You may also
connect an accessory battery charge unit
expressly approved by Mercedes-Benz for
your vehicle model to maintain the battery
charge. Contact an authorized Mercedes-
Benz Center for further information.
The battery, the battery ventilation hose
and the lateral plug must always be
securely installed when the vehicle is in
operation.
! Never loosen or detach battery terminal
clamps while the engine is running or the
SmartKey is in the starter switch or
KEYLESS-GO button is in position 1.
Otherwise the alternator and other
electronic components could be severely
damaged.
Have the battery checked regularly at an
authorized Mercedes-Benz Center.
Refer to Maintenance Booklet for
maintenance intervals or contact an
authorized Mercedes-Benz Center for
further information.
iMake sure the vehicle’s on-board
electronics have status 0 when you turn off
the engine and no longer require any
electrical consumers. The vehicle then
uses very little power and the battery is
spared.
iIf the battery is discharged, you must use
the mechanical key to unlock the vehicle.
iAfter battery power was interrupted, do
the following:
RSynchronize the power windows
(Y page 256).
RSynchronize the exterior rear view
mirrors (Y page 248).

Towing with rear axle raised
! The vehicle may be towed only for
distances up to 30 miles (50 km) and at a
speed not to exceed 30 mph (50 km/h).
When towing the vehicle with the rear axle
raised, the wheels on the ground have to
move freely. Therefore follow the respective
steps below, after the rear axle being raised:
XSwitch on the hazard warning flasher
( Y page 252).XMake sure the transmission remains in
neutral position N. Observe instructions,
see “Shifting into neutral position N”
( Y page 263).!
Because the ESC operates automatically,
the engine and ignition must be shut off
(KEYLESS-GO start/stop button in position
0 or 1, or SmartKey in starter switch
position 0 or 1) when the electronic parking
brake is being tested on a brake test
dynamometer or when the vehicle is being
towed with the rear axle raised.
Active braking action through the ESC may
otherwise seriously damage the brake
system which is not covered by the
Mercedes-Benz Limited Warranty.
! Keep in mind that it is important for the
SmartKey to be left in starter switch with
the ignition switched off. As soon as the
SmartKey is removed from the starter
switch the transmission will shift to park
position P.
Towing with all wheels on the ground
GWarning!
When there is a malfunction in the brake
system, the vehicle must be towed using a tow
bar.
Before towing make sure the steering wheel
is unlocked and can be moved.
The vehicle must not be towed when the
power supply or the vehicle’s electrical
system are malfunctioning.
GWarning!
While the vehicle is being towed,
R the engine may turn off
R the electrical system may fail
R the battery voltage may drop too far.
All or any of this will block the rear axle.
This could cause an accident and injure you
and/or others.
! You must not use the KEYLESS-GO start/
stop button when towing the vehicle. Use
the SmartKey instead.
