Adaptive brake lights
If you brake sharply from a speed of more
than 30 mph (50 km/h) or if braking is assis-ted by BAS, the brake lamps flash rapidly. In
this way, traffic traveling behind you is
warned in an even more noticeable manner.
If you brake sharply from a speed of more
than 45 mph (70 km/h)to a standstill, the
hazard warning lamps are activated automat-
ically. If the brakes are applied again, the
brake lamps light up continuously. The hazard
warning lamps are deactivated automatically if you drive faster than 6 mph (10 km/h). You
can also switch off the hazard warning lamps using the hazard warning button( Y page 90).
ESP®(Electronic Stability Program)
Important safety notes
iObserve the "Important safety notes" sec-
tion ( Ypage 64).
GWARNING
If ESP ®
is malfunctioning, ESP ®
is unable to
stabilize the vehicle. Additionally, further driv- ing safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP ®
checked at a
qualified specialist workshop.
!Only operate the vehicle for a maximum of
ten seconds on a brake test dynamometer.
Switch off the ignition.
Application of the brakes by ESP ®
may oth-
erwise destroy the brake system.
!A function or performance test should
only be carried out on a two-axle dyna-
mometer. Before you operate the vehicle
on such a dynamometer, please consult a
qualified workshop. You could otherwise
damage the drive train or the brake system. ESP
®
monitors the driving stability and the
traction. Traction is the power transmission
between the tires and the road surface. ESP ®
is deactivated if the åwarning lamp
in the instrument cluster lights up continu-
ously when the engine is running.
If the ÷ warning lamp and the åwarn-
ing lamp are lit continuously, ESP ®
is not
available due to a malfunction.
Observe the information on warning lamps ( Y page 165) and display messages which
may be displayed in the instrument cluster( Y page 148).
If ESP ®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilize the
vehicle. If necessary, the engine output is also modified to keep the vehicle on the desired
course within physical limits. ESP ®
assists
the driver when pulling away on wet or slip-
pery roads. ESP ®
can also stabilize the vehi-
cle during braking.
If ESP ®
intervenes, the ÷warning lamp
flashes in the instrument cluster.
If ESP ®
intervenes:
X Do not deactivate ESP ®
under any circum-
stances.
X Only depress the accelerator pedal as far as
necessary when pulling away.
X Adapt your driving style to suit the prevail-
ing road and weather conditions.
iOnly use wheels with the recommended
tire sizes. Only then will ESP ®
function
properly.
iIf differential locks are switched on, ABS,
BAS and ESP ®
switch off automatically.

GWarning
A flat tire severely impairs the driving, steer-
ing 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.
Contact an authorized Mercedes-Benz Center if you require information on tested and rec- ommended wheels and tires for summer and
winter driving. Advice on purchasing and car-
ing 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 work-
shop and ask about:
R suitability
R legal stipulations
R factory recommendations
Information on the dimensions and types of
wheels and tires for your vehicle can be found
in the "Wheel/tire combinations" section( Y page 254).
Information on air pressure for the tires on
your vehicle can be found:
R on the tire pressure label on the fuel fillerflap
R in the "Tire pressure" section
iFurther 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. Oth-
erwise, the tires, particularly the sidewalls,
may be damaged.
230Operation
Wheels and tires

Selecting, mounting and replacing tires
ROnly 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 mod-
erate speeds for the first 60 miles
(100 km). They only reach their full per-
formance 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 lat-
est, regardless of wear. This also applies to
the spare wheel.
Winter operation
You can find information about this in the
Digital Operator's Manual.
Tire pressure
Tire pressure specifications
Important safety notes
GWARNING
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 steer-
ing 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 includ-
ing 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.
iThe specifications on the sample Tire and
Loading Information placard and tire pres-
sure tables are examples. Tire pressure
specifications are vehicle-specific and may
deviate from the data shown here. The tire pressure specifications that are valid for
your vehicle can be found on the Tire and
Loading Information placard and tire pres-
sure table on the vehicle.
General notes
The recommended tire pressures for the tires
mounted at the factory can be found on the
labels described here.
Operation with a trailer: the applicable
value for the rear tires is the maximum tire
pressure value stated in the table inside the
fuel filler flap.
Further information on tire pressures can be
obtained at a qualified specialist workshop.
Tire and Loading Information placard
:Recommended tire pressures
232Tire pressure
Wheels and tires

The Tire and Loading Information placard is
on the B-pillar on the driver's side(Y page 238).
The Tire and Loading Information placard con- tains the recommended tire pressures for
cold tires. The recommended tire pressures
are valid for the maximum permissible load
and up to the maximum permissible vehiclespeed.
Tire pressure table
Example: tire pressure table for all tires permitted
for this vehicle by the factory
The tire pressure table is on the inside of thefuel filler flap.
The tire pressure table contains the recom-
mended pressures for cold tires for various
operating conditions, i.e. differing load and
speed conditions.
If a tire size precedes a tire pressure, the tirepressure information following is only valid
for that tire size. The load conditions "partially
laden" and "fully laden" are defined in the
table for different numbers of occupants and amounts of luggage. The actual number of
seats may differ.
Some tire pressure tables only show the rim
diameter instead of the complete tire size,e.g. R16 . Rim diameter is part of the tire size
and can be found on the tire sidewall( Y page 244). If the tire pressures have been set to the
lower values for lighter loads and/or lower
road speeds, the pressures should be reset to
the higher values:
R if you want to drive with an increased loadand/or
R if you want to drive at higher road speeds
iThe tire pressures for increased loads
and/or higher road speeds, shown in the
tire pressure table, may have a negative
effect on driving comfort.
If the tire pressure is not set correctly, this
can lead to an excessive build-up of heat and a sudden loss of pressure.
For more information, contact a qualified spe-
cialist workshop.
Important notes on tire pressure
GWARNING
If the tire pressure drops repeatedly, the
wheel, valve or tire may be damaged. Tire
pressure that is too low may result in a tire
blow-out. There is a risk of an accident.
R Check the tire for foreign objects.
R Check whether the wheel is losing air or the
valve is leaking.
If you are unable to rectify the damage, con-
tact a qualified specialist workshop.
GWARNING
If you fit unsuitable accessories onto tire
valves, the tire valves may be overloaded and malfunction, which can cause tire pressure
loss. Due to their design, retrofitted tire pres- sure monitors keep the tire valve open. This
can also result in tire pressure loss. There is a
risk of an accident.
Only screw the standard valve cap or other
valve caps approved by Mercedes-Benz for
your vehicle onto the tire valve.
Use a suitable pressure gauge to check the
tire pressure. The outer appearance of a tire
does not permit any reliable conclusion about
Tire pressure233

Maximum tire pressures
:Example: maximum permissible tire pres-sure
Never exceed the maximum permissible tire
inflation pressure. Always observe the rec-
ommended tire pressure for your vehicle
when adjusting the tire pressure( Y page 248).
iThe actual values for tires are vehicle-
specific and may deviate from the values in
the illustration.
Checking the tire pressures
Important safety notes
Observe the notes on tire pressure ( Y page 232).
Information on air pressure for the tires on
your vehicle can be found:
R on the tire pressure label on the fuel fillerflap
R in the "Tire pressure data" section(Y page 232)
Checking tire pressures manually
To determine and set the correct tire pres-
sure, proceed as follows: X
Remove the valve cap of the tire that is to
be checked.
X Press the tire pressure gauge securely onto
the valve. X
Read the tire pressure and compare it to
the recommended value on the Tire and
Loading Information placard on fuel filler
flap of your vehicle ( Ypage 233).
X The tire pressure is too low: increase the
tire pressure to the recommended value.
X The tire pressure is too high: press down
the metal pin in the valve using the tip of a
pen, for example.
Air is released from the tire.
X Check the tire pressure again with the tire
pressure gauge.
X Screw the valve cap onto the valve.
X Repeat these steps for the other tires.
Tire pressure monitor
Important safety notes
GWARNING
Each tire, including the spare (if provided),
should be checked at least once a month
when cold and inflated to the pressure rec-
ommended by the vehicle manufacturer on
the Tire and Loading Information placard on
the driver's door B-pillar or the tire 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 Infor-
mation placard or the tire pressure label, you should determine the proper tire pressure for
those tires.
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoringsystem (TPMS) that illuminates a low tire pres-
sure 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 underin-
flated 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 stop-
ping ability.
