Important safety notes
Special tools and expert knowledge are
required when working on the battery, e.g.
removal and installing. You should therefore
have all work involving the battery carried out
at a qualified specialist workshop. G
WARNING
Work carried out incorrectly on the battery
can lead, for example, to a short circuit and
thus damage the vehicle electronics. This can
lead to function restrictions applying to
safety-relevant systems, e.g. the lighting
system, ABS (anti-lock braking system) or
ESP ®
(Electronic Stability Program). The
operating safety of your vehicle may be
restricted. You could lose control of the
vehicle, for example:
R braking
R in the event of abrupt steering maneuver
and/or when the vehicle's speed is not
adapted to the road conditions
There is a risk of an accident.
In the event of a short circuit or a similar
incident, contact a qualified specialist
workshop immediately. Do not drive any
further. You should have all work involving the
battery carried out at a qualified specialist
workshop.
If ABS malfunctions, the wheels can lock
during braking. This limits the steerability of
the vehicle when braking and may increase
the braking distance.
If ESP ®
malfunctions, the vehicle will not be
stabilized if it starts to skid or a wheel starts
to spin. G

WARNING
Replace rims or tires with the same
designation, manufacturer and type as shown
on the original part. For further information
contact an authorized Mercedes-Benz Center.
If incorrectly sized rims and tires are
mounted, the wheel brakes or suspension
components can be damaged. Also, the
operating clearance of the wheels and the
tires may no longer be correct. G
WARNING
Worn, old tires can cause accidents. If the tire
tread is worn to minimum tread depth, or if
the tires have sustained damage, replace
them.
When replacing rims, only use genuine
Mercedes-Benz wheel bolts specified for the
particular rim type. Failure to do so can result
in the bolts loosening and possibly an
accident.
Retreaded tires are not tested or
recommended by Mercedes-Benz, since
previous damage cannot always be
recognized on retreads. The operating safety
of the vehicle cannot be assured when such
tires are used. G
WARNING
If you notice sudden significant vibrations or
unusual handling performance or if you
suspect that damage has occurred to the
vehicle, you should activate the hazard
warning lamps, gently reduce speed and
carefully head for an area that is located at a
safe distance from the road.
Check the tires and the underside of the
vehicle for damage. If the vehicle seems
unsafe, have the vehicle towed away to the
nearest Mercedes-Benz Center or tire dealer
to be repaired. G
WARNING
Do not drive with a flat tire. A flat tire affects
the ability to steer or brake the vehicle. You
might lose control of the vehicle. Continued
driving with a flat tire or driving at high speed
with a flat tire will cause excessive heat build-
up and possibly a fire. G
Warning
A flat tire severely impairs the driving,
steering and braking characteristics of the
vehicle. There is a risk of an accident.
do not drive with a flat tire. Immediately
replace the flat tire with your spare wheel, or
consult a qualified specialist workshop.
Consult an authorized Mercedes-Benz Center
if you require information on approved and
recommended tires and wheels for summer
and winter operation. Advice on purchasing
and caring for tires is also available there.
Accessories that are not approved for your
vehicle by Mercedes-Benz or are not being
used correctly can impair the operating
safety.
Before purchasing and using non-approved
accessories, visit a qualified specialist
workshop and ask about:
R suitability
R legal stipulations
R factory recommendations 228
Important safety notesWheels and tires

Information on the dimensions and types of
wheels and tires for your vehicle can be found
in the "Wheel/tire combinations" section
(Y page 253).
Information on air pressure for the tires on
your vehicle can be found:
R on the tire pressure label on the fuel filler
flap
R in the "Tire pressure" section
i Further information on wheels and tires
can be obtained at any qualified specialist
workshop. Operation
Notes on driving
If the vehicle is heavily loaded, check the tire
pressures and correct them if necessary.
When parking your vehicle, make sure that
the tires do not get deformed by the curb or
other obstacles. If it is necessary to drive over
curbs, speed humps or similar elevations, try
to do so slowly and at an obtuse angle.
Otherwise, the tires, particularly the
sidewalls, may be damaged. Regular checking of wheels and tires
G
WARNING
Regularly check the tires for damage.
Damaged tires can cause tire inflation
pressure loss. As a result, you could lose
control of your vehicle.
Worn, old tires can cause accidents. If the tire
tread is worn to minimum tread depth, or if
the tires have sustained damage, replace
them.
R Regularly check the wheels and tires of
your vehicle for damage at least once a
month, as well as after driving off-road or
on rough roads. Damage includes bulges
and deformation on tires, cuts, punctures,
cracks or severe corrosion on wheels, for example. Damaged wheels can cause a
loss of tire pressure.
R Regularly check the tire tread depth and
the condition of the tread across the whole
width of the tire (Y page 229). In order to
inspect the inner side of the tire surface,
turn the steering wheel to full lock.
R All wheels must have a valve cap to protect
the valve against dirt and moisture. Do not
install anything onto the valve other than
the standard valve cap or a valve cap
approved by Mercedes-Benz for your
vehicle.
Do not install anything onto the valve, such
as tire pressure monitoring systems.
R You should regularly check the pressure of
all your tires including the spare wheel,
particularly prior to long trips. Adjust the
tire pressure as necessary (Y page 236).
The service life of tires depends, among other
things, on the following factors:
R driving style
R tire pressure
R distance covered Tire tread
G
WARNING
Although the applicable federal motor vehicle
safety laws consider a tire to be worn when
the treadwear indicators (TWI) become visible
at approximately áinches (1.6 mm), we
recommend that you do not allow your tires
to wear down to that level. As tread depth
approaches âinches (3 mm) the adhesion
properties on a wet road are sharply reduced.
Depending upon the weather and/or road
surface (conditions), the tire traction varies
widely. Operation
229Wheels and tires Z

Marking
:shows the tread wear indicator
(TWI). The arrow indicates the placement of
the tire tread.
Do not drive with tires which have too little
tread depth. tire traction on wet road surfaces
decreases significantly when the tread depth
is less than 1
/ 8 in (3 mm).
Treadwear indicators (TWI) are required by
law. Six indicators are positioned over the tire
tread. They are visible once the tread depth
is approximately 1
/ 16 in (1.6 mm). If this is the
case, the tire is so worn that it must be
replaced.
The recommended tread depth for summer
tires is at least 1
/ 8 in (3 mm). The
recommended tread depth for winter tires is
at least 1
/ 6 in (4 mm). Selecting, mounting and replacing
tires
R Only mount tires and wheels of the same
type and make.
R Only mount approved tires of the correct
size onto the wheels.
R Tires are supplied with a protective layer
from the factory. Break in new tires at
moderate speeds for the first 60 miles
(100 km). They only reach their full
performance after this distance. R
Do not drive with tires which have too little
tread depth, as this significantly reduces
the traction on wet roads (hydroplaning).
R Replace the tires after six years at the
latest, regardless of wear. This also applies
to the spare wheel. Winter operation

Important safety notes G
WARNING
Underinflated or overinflated tires pose the
following risks:
R the tires may burst, especially as the load
and vehicle speed increase.
R the tires may wear excessively and/or
unevenly, which may greatly impair tire
traction.
R the driving characteristics, as well as
steering and braking, may be greatly
impaired.
There is a risk of an accident.
Follow recommended tire inflation pressures
and check the pressure of all the tires
including the spare wheel:
R monthly, at least
R if the load changes
R before beginning a long journey
R under different operating conditions, e.g.
off-road driving
If necessary, correct the tire pressure.

vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to
continue to function properly.
It is the driver's responsibility to set the tire
pressure to the recommended cold tire
pressure suitable for the operating situation
(Y page 230). Note that the correct tire
pressure for the current operating situation
must first be taught-in to the tire pressure
monitor. If there is a substantial loss of
pressure, the warning threshold for the
warning message is aligned to the reference
values taught-in. Restart the tire pressure
monitor after adjusting to the cold tire
pressure (Y page 236). The current
pressures are saved as new reference values.
As a result, a warning message will appear if
the tire pressure drops significantly.
The tire pressure monitor does not warn you
of an incorrectly set tire pressure. Observe
the notes on the recommended tire pressure
(Y page 230).
The tire pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the
tire is penetrated by a foreign object. In the
event of a sudden loss of pressure, bring the
vehicle to a halt by braking carefully. Avoid
abrupt steering maneuvers.
If a tire pressure monitor system is installed,
the vehicle's wheels have sensors installed
that monitor the tire pressures in all four tires.
The tire pressure monitor warns you if the
pressure drops in one or more of the tires. The
tire pressure monitor only functions if the
correct wheel electronics units are installed
on each wheel.
The tire pressure monitor has a yellow
warning lamp in the instrument cluster for
indicating pressure loss/malfunctions (USA)
or pressure loss (Canada). Whether the
warning lamp flashes or lights up indicates
whether a tire pressure is too low or the tire
pressure monitor is malfunctioning:
R if the warning lamp is lit continuously, the
tire pressure on one or more tires is significantly too low. The tire pressure
monitor is not malfunctioning.
R USA only: if the warning lamp flashes for
around a minute and then remains lit
constantly, the tire pressure monitor is
malfunctioning.
Information on tire pressures is displayed in
the multifunction display. After a few minutes
of driving, the current tire pressure of each
tire is shown in the multifunction display.
USA only: if there is a malfunction with the
tire pressure monitor it can take more than
ten minutes until the malfunction is shown by
the tire pressure warning lamp flashing for
approximately one minute and then lighting
up continuously. When the malfunction has
been rectified, the tire pressure warning lamp
goes out after a few minutes of driving.
The tire pressure values indicated by the on-
board computer may differ from those
measured at a gas station with a pressure
gauge. The tire pressures shown by the on-
board computer refer to those measured at
sea level. At high altitudes, the tire pressure
values indicated by a pressure gauge are
higher than those shown by the on-board
computer. In this case, do not reduce the tire
pressures.
The operation of the tire pressure monitor can
be affected by interference from radio
transmitting equipment (e.g. radio
headphones, two-way radios) that may be
being operated in or near the vehicle.
i USA only:
This device complies with part 15 of the
FCC Rules. Operation is subject to the
