Warning!
G
To prevent possible personal injury, always
keep hands and fingers away from the trunk
opening when closing the trunk. Be espe-
cially careful when small children are
around.
Warning!

Only drive with the trunk closed as, among
other dangers such as visibility blockage,
exhaust fumes may enter the vehicle
interior.iDo not place the SmartKey in the open
trunk. You may lock yourself out.
Vehicles with KEYLESS-GO:
To prevent a possible inadvertent lock-
out, the trunk lid will open automatical-
ly if a SmartKey with KEYLESS-GO is
recognized inside the vehicle or in the
trunk.

268 OperationDriving instructionsPower assistance
Brakes
Warning!
G
The brake system requires electrical energy
for operation.
A malfunction in the vehicle’s power supply
or electrical system may impair brake sys-
tem operation and switch it into its emer-
gency operation mode. In such a case, the
red brake warning lamp (
page 312) and
warning messages in the instrument cluster
(
page 318) come on while driving. To
brake, the driver must then apply signifi-
cantly greater brake pedal pressure and de-
press the pedal much further to obtain the
expected braking effect. If necessary, apply
full pressure to the brake pedal. Brakes may
only be applied to the front wheels. Stop-
ping distance is increased! If there is a mal-
function in the SBC brake system, we
recommend that the vehicle be transported
with all wheels off the ground using flatbed
or appropriate wheel lift/dolly equipment. A
tow bar must be used if circumstances do
not permit the use of the recommended
towing methods and the vehicle requires
towing with all four wheels on the ground.
Towing the vehicle with all four wheels on
the ground is only permissible for distances
up to 30 miles (50 km) and at a speed not to
exceed 30 mph (50 km/h). For more infor-
mation, refer to “Towing the vehicle”
(page 381). For more information see
SBC brake system (
page 79).
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.
Warning!
G
After driving in heavy rain for some time
without applying the brakes or through wa-
ter deep enough to wet brake components,
the first braking action may be somewhat
reduced and increased pedal pressure may
be necessary to obtain expected braking ef-
fect. Maintain a safe distance from vehicles
in front.
Resting your foot on the brake pedal will
cause excessive and premature wear of the
brake pads.
It can also result in the brakes overheating,
thereby significantly reducing their effec-
tiveness. It may not be possible to stop the
vehicle in sufficient time to avoid an acci-
dent.

Removing the spare wheel
Turn luggage bowl counterclockwise.
Remove spare wheel2.
Storing the spare wheel
Place spare wheel2 in wheel well.
Turn luggage bowl clockwise to its stop
to secure the spare wheel.Minispare wheel
In the case of a flat tire, you may tempo-
rarily use the Minispare wheel when ob-
serving the following restrictions:
Do not exceed a vehicle speed of
50 mph (80 km / h).
Drive to the nearest tire repair facility
to have the flat tire repaired or re-
placed as appropriate.
Do not operate vehicle with more than
one spare wheel mounted.More information can be found in the
“Technical data” section (
page 396).

Lift luggage box in the area of the fas-
tening bolts and remove it from trunk.
!Always lower trunk floor before closing
trunk lid.
Warning!
G
The dimensions of the Minispare wheel are
different from those of the road wheels. As
a result, the vehicle handling characteristics
change when driving with a Minispare wheel
mounted.
The Minispare wheel should only be used
temporarily, and replaced with a regular
road wheel as quickly as possible.

TIREFIT is a limited repair device. TIREFIT
cannot be used for:
cuts or punctures larger than approxi-
mately 0.16 in (4 mm)
on a flat tire, or a damaged wheel
tire damage caused by driving with ex-
tremely low tire pressure
Do not drive the vehicle under such circum-
stances.
Contact your nearest Mercedes-Benz
Center for assistance or call Roadside Assis-
tance.

Do not exceed vehicle speed of 50 mph
(80 km / h). A TIREFIT repair is not designed
to operate at higher speeds.

If tire pressure has fallen below
20 psi (1.3 bar) do not continue to drive the
vehicle.
Park your vehicle safely away from the road-
way and contact the nearest authorized
Mercedes-Benz Center or Roadside Assis-
tance.
If ti re pre ss ur e i s at l ea st 2 0 psi (1 .3 ba r ), in -

Visit an authorized Mercedes-Benz
Center as soon as possible to obtain a
new TIREFIT container.
Bring used TIREFIT materials to an au-
thorized Mercedes-Benz Center for
proper disposal.
Replace your TIREFIT container every
four years. Replacement containers are
available at your authorized
Mercedes-Benz Center.
Mounting the spare wheel
Preparing the vehicle
Prepare the vehicle as described under
“Preparing the vehicle” on this page.
Take the spare wheel out of the trunk
(page 350).
Lifting the vehicle
Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
(not included) or other sizable objects.
When changing wheel on a level surface:
Place one chock in front of and one be-
hind the wheel that is diagonally oppo-
site to the wheel being changed.
Warning!
G
Follow recommend inflation pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes
etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
Do not overload the tires by exceeding the
specified vehicle capacity weight (as indicat-
ed by the label on the pillar in the driver’s
door opening). Overloading the tires can
overheat them, possibly causing a blowout.
Warning!
G
Do not exceed vehicle speed of 50 mph
(80 km / h). A TIREFIT repair is not designed
to operate at higher speeds.
The sticker must be attached on the instru-
ment cluster where it will be easily seen by
the driver.
Vehicle handling characteristics may
change. Adapt your driving accordingly.

Flat tire
When changing wheel on a hill:
Place chocks on the downhill side
blocking both wheels of the other axle.
Take the two-piece wheel wrench and
the jack out of the trunk (
page 352).
Assemble wheel wrench.
On wheel to be changed, loosen but do
not yet remove the wheel bolts (ap-
proximately one full turn with wrench). The jack take-up brackets are located di-
rectly behind the front wheel housing and
in front of the rear wheel housing.
1Jack take-up bracket
2Jack
3Crank
Position jack2 on firm ground under
the respective jack take-up bracket1.
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
on level surface. Be sure that the jack arm is
fully seated in the jack take-up bracket. Al-
ways lower the vehicle onto sufficient ca-
pacity jackstands before working under the
vehicle.
