Recommended tire inflation pressureGWarning!
Follow recommended tire inflation pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly, adversely
affect handling and fuel economy, and are
more likely to fail from being overheated.
Do not overinflate tires. Overinflated tires can
adversely affect handling and ride comfort,
wear unevenly, increase stopping distance,
and result in sudden deflation (blowout)
because they are more likely to become
punctured or damaged by road debris,
potholes etc.
Do not overload the tires by exceeding the
specified load limit as indicated on the Tire
and Loading Information placard on the
driver’s door B-pillar. Overloading the tires
can overheat them, possibly causing a
blowout. Overloading the tires can also result
in handling or steering problems, or brake
failure.
Your vehicle is equipped with the Tire and
Loading Information placard located on the
driver’s door B-pillar (Y page 237).
The tire inflation pressure should be checked
regularly. Only adjust the tire inflation
pressure on cold tires. The tires can be
considered cold if the vehicle has been
parked for at least 3 hours or driven less than
1 mile (1.6 km). Depending on the ambient
temperature, the driving speed and the tire
load, the tire temperature changes. When the
tire temperature changes by 18‡ (10†), the
tire inflation pressure will change by
approximately 1.5 psi (0.1 bar). Keep this in
mind when checking tire inflation pressure on
warm tires and adjust the tire pressure only
if the tire inflation pressure is too low for the
current operating conditions. If you check the
tire inflation pressure when the tires are
warm, the reading will be higher than the cold
reading. This is normal. Do not let air out to
match the specified cold tire inflation
pressure. Otherwise, the tire will be
underinflated.
Follow recommended cold tire inflation
pressures listed on Tire and Loading
Information placard on the driver’s door
B-pillar.
Keeping the tires properly inflated provides
the best handling, tread life and riding
comfort.
In addition to the Tire and Loading
Information placard on the driver’s door
B-pillar, also consult the tire inflation
pressure label on the inside of the filler flap
for any additional information pertaining to
special driving situations. For more
information, see “Important notes on tire
inflation pressure” (Y page 230).

Tire pressure loss warning system
(Canada only)
While the vehicle is being driven, the tire
pressure loss warning system monitors the
set tire inflation pressures by evaluating each
wheel’s rotational speed. This allows the
system to detect a significant loss of pressure
in a tire. If a wheel’s rotational speed changes
due to falling tire inflation pressure, you will
see a corresponding warning message in the
multifunction display.
The tire pressure loss warning system may
function in a restricted manner or with a delay
R when snow chains are mounted to the
vehicle
R in the presence of ice and snow
R when you are driving on a loose surface
(e.g. sand or gravel)
R when you are driving in a very sporty
manner (involving rapid acceleration or
high speeds in curves)
GWarning!
When the multifunction display shows the
message Check Tire Pressure Soon , one
or more of your tires are significantly
underinflated. You should stop and check
your tires as soon as possible, and inflate
them to the proper tire inflation pressure as
indicated on the vehicle’s Tire and Loading
Information placard or, if available, on the tire
inflation pressure label.
Driving on a significantly underinflated tire
causes the tire to overheat and can lead to
tire failure. Underinflation also reduces fuel
efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
Each tire, including the spare, should be
checked at least once a month when cold.
Inflate the tires to the recommended tire
inflation pressure as specified on
R the Tire and Loading Information placard on
the driver’s door B-pillar
or
R the tire inflation pressure label located on
the inside of the fuel filler flap

The tire pressure loss warning system does
not provide a warning for wrongly selected tire
inflation pressures. Always adjust tire
inflation pressure according to the Tire and
Loading Information placard on the driver’s
door B-pillar or on the tire inflation pressure
label located on the inside of the fuel filler flap.
The tire pressure loss warning system does
not replace regular checks of the tire inflation
pressures since a gradual pressure loss in
more than one tire cannot be detected by the
tire pressure loss warning system.
The tire pressure loss warning system is not
able to issue a warning due to a sudden
dramatic loss of tire inflation pressure (e.g.
tire blowout caused by a foreign object). In
this case bring the vehicle to a halt by carefully

GWarning!
The TPMS does not indicate a warning for
wrongly selected inflation pressures. Always
adjust tire inflation pressure according to the
Tire and Loading Information placard or the
supplemental tire inflation pressure
information on the inside of the fuel filler flap.
The TPMS is not able to issue a warning due
to a sudden dramatic loss of pressure (e.g. tire
blowout caused by a foreign object). In this
case bring the vehicle to a halt by carefully
applying the brakes and avoiding abrupt
steering maneuvers.
GWarning!
Each tire, including the spare (if provided),
should be checked at least once a month
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the Tire and Loading
Information placard on the driver’s door B-
pillar or the tire inflation pressure label on the
inside of the fuel filler flap. If your vehicle has
tires of a different size than the size indicated
on the Tire and Loading Information placard
or the tire inflation pressure label, you should
determine the proper tire inflation pressure
for those tires.
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires are significantly underinflated.
Accordingly, when the low tire pressure
telltale illuminates, you should stop and check
your tires as soon as possible, and inflate
them to the proper pressure. Driving on a
significantly underinflated tire causes the tire
to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency
and tire tread life, and may affect the vehicle’s
handling and stopping ability. Please note that
the TPMS is not a substitute for proper tire
maintenance, and it is the driver’s
responsibility to maintain correct tire
pressure, even if underinflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
USA only:
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the
system detects a malfunction, the telltale will
flash for approximately 1 minute and then
remain continuously illuminated. This
sequence will continue upon subsequent
vehicle start-ups as long as the malfunction
exists. When the malfunction indicator is
illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of
incompatible replacement or alternate tires
or wheels on the vehicle that prevent the
TPMS from functioning properly. Always
check the TPMS malfunction telltale after
replacing one or more tires or wheels on your
vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to
continue to function properly.
i USA only:
If a condition causing the TPMS to
malfunction develops, it may take up to
10 minutes for the system to signal a
malfunction using the TPMS telltale
flashing and illumination sequence.
The telltale extinguishes after a few
minutes driving if the malfunction has been
corrected.
Tire pressure inquiries are made using the
multifunction display. The current tire
inflation pressure for each tire appears in the
multifunction display after a few minutes of
driving.

readings of a tire pressure gauge of an air
hose, e.g. gas station equipment, and the

Restarting Advanced TPMS
GWarning!
It is the driver’s responsibility to set the tire
inflation pressure to the recommended cold
tire inflation pressure. Underinflated tires
affect the ability to steer or brake the vehicle.
You might lose control over the vehicle.
When you restart the TPMS, the system sets
new reference values for each tire.
The TPMS must be restarted when you have
adjusted the tire inflation pressure to a new
level (e.g. because of different load or driving
conditions). The TPMS is then recalibrated to
the current tire inflation pressures.
iCanada only:
The TPMS usually recognizes tire pressure
adjustments and sets new reference values
automatically. You can, however, restart
the TPMS manually as described.
Restart the TPMS after adjusting the tire
inflation pressure to the inflation pressure
recommended for the vehicle operating
condition. Tire inflation pressure should only
be adjusted on cold tires. Observe the
recommended tire inflation pressure on the
Tire and Loading Information placard on the
driver’s door B-pillar. Some vehicles may have
supplemental tire inflation pressure
information for driving at high speeds or for
vehicle loads less than the maximum loaded
vehicle condition. If such information is
provided, it can be found on the inside of the
fuel filler flap.
XUsing the Tire and Loading Information
placard on the driver’s door B-pillar
(Y page 237) or the supplemental tire

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 efficiency
should be tested as soon as possible after
driving is resumed.GWarning!
Make sure not to endanger any other road
users when carrying out these braking
maneuvers.
Driving instructions
Drive sensibly – save fuel
To save fuel you should:
R Keep tires at the recommended inflation
pressures.
R Remove unnecessary loads.
R Remove roof rack when not in use.
R Allow engine to warm up under low load
use.
R Avoid frequent acceleration and
deceleration.
R Have all maintenance work performed at
the intervals specified in the Maintenance
Booklet and as required by the
Maintenance system. Contact an
authorized Mercedes-Benz Center.
Fuel consumption is also increased by driving
in cold weather, in stop-and-go traffic, on
short trips and in mountainous areas.
Drinking and driving
GWarning!
Drinking and driving and/or taking drugs and
driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and
judgment.
The possibility of a serious or even fatal
accident are greatly increased when you drink
or take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
taking drugs.
Pedals
GWarning!
Make sure absolutely no objects are
obstructing the pedals’ range of movement.
Keep the driver’s footwell clear of all
obstacles. If there are any floormats or
carpets in the footwell, make sure that the
pedals still have sufficient clearance.
During sudden driving or braking maneuvers,
the objects could get caught between the
pedals. You could then no longer brake or
accelerate. This could lead to accidents and
injury.
Power assistance
GWarning!
There is no power assistance for the steering
and the brake when the engine is not running.
Steering and braking requires significantly
more effort and you could lose control of the
vehicle and cause an accident as a result.
Do not turn off the engine while the vehicle is
in motion.
Brakes
Downhill grades
! When driving down long and steep
grades, relieve the load on the brakes by
shifting into a lower gear to use the
engine’s braking power. This helps prevent
overheating of the brakes and reduces
wear.

Moreover, tires and rims not approved by
Mercedes-Benz may, under load, exhibit
dimensional variations and different tire
deformation characteristics that could
cause them to come into contact with the
vehicle body or axle parts. Damage to the
tires or the vehicle may be the result.
i Further information on tires and rims is
available at any authorized Mercedes-Benz
Center. The Tire and Loading Information
placard with the recommended tire
inflation pressures for cold tires is located
on the driver’s door B-pillar. Supplemental
tire inflation pressure information for
driving at high speeds or for vehicle loads
less than the maximum loaded vehicle
condition can be found on the tire inflation
pressure label. The tire inflation pressure
label is located on the inside of the fuel filler
flap. The tire inflation pressure should be
checked regularly and should only be
adjusted on cold tires. Follow tire
manufacturer’s maintenance
recommendation included with the vehicle.
For information on recommended tire
inflation pressure and supplemental tireinflation pressure information for special
driving situations, see ( Y page 229).
i Please keep in mind that the vehicle must
be equipped
R with wheels of identical dimensions on
each axle (left and right)
R with tires of identical characteristics all
around, i.e. summer tires, winter tires,
all-season tires, or MOExtended tires etc.
i The following pages also list the approved
rim and tire sizes for equipping your vehicle
with winter tires. Winter tires are not
available as standard or optional factory
equipment, but can be purchased from an
authorized Mercedes-Benz Center.
Equipping your vehicle with winter tires
approved for your vehicle model may
require the purchase of rims of the
recommended size for use with these
winter tires. This depends on vehicle model
