! To prevent damage to the catalytic
converters, only use premium unleaded
gasoline in this vehicle.
Any noticeable irregularities in engine
operation should be repaired promptly.

overheat and potentially start a fire.
i Only use premium unleaded gasoline with
a minimum Posted Octane Rating of 91
(average of 96 RON/86 MON).
Information on gasoline quality can
normally be found on the fuel pump. Please
contact gas station personnel in case
labels on the pump cannot be found.
For more information on gasoline, see

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 feel a sudden significant vibration or
ride disturbance,
or you suspect that possible
damage to your vehicle has occurred, you
should turn on the hazard warning flashers,
carefully slow down, and drive with caution to
an area which is a safe distance from the road.
Inspect the tires and the vehicle underbody
for possible damage. If the vehicle or tires
appear unsafe, have the vehicle towed to the
nearest authorized Mercedes-Benz Center or
tire dealer for repairs. G
Warning!
Do not drive with a flat tire. A flat tire affects
the ability to steer or brake the vehicle. You
could 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. Important guidelines
R Only use
sets of tires and rims of the same
type and make.
R Tires must be of the correct size for the rim.
R Break in new tires for approximately
60 miles (100 km) at moderate speeds.
R Regularly check the tires and rims for
damage. Dented or bent rims can cause tire
inflation pressure loss and damage to the
tire beads.
R If the vehicle is heavily loaded, check tire
inflation pressure and correct as required.
R Do not allow your tires to wear down too
far. Adhesion properties on wet roads are sharply reduced at tread depths of less
than
1
/ 8 in (3 mm).
R When replacing
individual tires, you should
mount new tires on the front wheels first
(on vehicles with same-sized wheels all
around). Recommended tire inflation pressure
G
Warning!
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 381).
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 374

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 375).
i Data shown on Tire and Loading
Information placard example are for
illustration purposes only. Tire data are
specific to each vehicle and may vary from
data shown in the following illustration.
Refer to Tire and Loading Information
placard on vehicle for actual data specific
to your vehicle. The Tire and Loading Information placard lists
the recommended cold tire inflation pressures
: for maximum loaded vehicle
weight. The tire inflation pressures listed
apply to the tires installed as original
equipment.
Important notes on tire inflation
pressure G
Warning!
If the tire inflation pressure drops repeatedly,
check the tires for punctures from foreign
objects and/or whether air is leaking from the
valves or from around the rim.
Tire temperature and tire inflation pressure
are also increased while driving, depending
on the driving speed and the tire load.
If you will be driving your vehicle at high
speeds of 100 mph (160 km/h) or higher,
where it is legal and conditions allow, consult
the tire inflation pressure label on the inside
of the fuel filler flap on how to adjust the cold
tire inflation pressure. If you do not adjust the
tire inflation pressure, excessive heat can
build up and result in sudden tire failure.
If you are not sure about the proper tire
inflation, contact an authorized Mercedes-
Benz Center.
i Driving comfort may be reduced when the
tire inflation pressure is adjusted to the
value for speeds above 100 mph
(160 km/h) as specified on the tire inflation
pressure label located on the inside of the
fuel filler flap.
Make sure to readjust the tire inflation
pressure for normal driving speeds.
