A multifunction display showing the message
“TIRE PRESSURE – CHECK TIRES!” indicates a much

Notes:
To ensure proper functioning of the tire inflation
pressure monitor, the tire inflation pressure should be
checked and corrected according to the label affixed
inside the fuel filler flap. For a detailed description,
refer to page 351.
The message “REACTIVATE – TIRE PRESS. MONITOR”
appears if the tire inflation pressure shows an increase
of 4.4 psi (0.3 bar) or more. Reactivate the tire inflation
pressure monitor.
The tire inflation pressure monitor only functions on
wheels equipped with the proper electronic sensors.
Inquire at your authorized Mercedes-Benz Center about
retrofitting other than original Mercedes-Benz wheels
with electronic sensors.
Transporting a deflated road wheel in the vehicle, e.g.
after having a flat, the tire inflation pressure monitor
should only be activated once the flat tire and rim are
removed from the vehicle.To prevent possible damage to the electronic sensors,
have tire changes only performed at an authorized
Mercedes-Benz Center.
For malfunction and warning messages, see page 318.
When checking the tire inflation pressure of the road
wheels, also check the spare tire.
The tire inflation pressure of the spare wheel, mounted
or not mounted, is not monitored by the tire inflation
pressure monitor.
See page 341 for location of the spare wheel, and
page 351 for tire inflation pressure.

Drive sensibly – save fuel
Fuel consumption, to a great extent, depends on driving
habits and operating conditions.
To save fuel you should:
•keep tires at the recommended inflation pressures.
•remove unnecessary loads,
•remove roof rack when not in use,
•allow engine to warm up under low load use,
•avoid frequent acceleration and deceleration,
•have all maintenance work performed at regular
intervals by an authorized Mercedes-Benz Center.
Fuel consumption is also increased by driving in cold
weat her, i n stop -and -go traf f ic, on short trip s an d i n hilly
country.Drinking and driving
Ped al s
Wa r n i n g !
Drinking or taking drugs and driving can be a very
dangerous combination. Even a small amount of
alcohol or drugs can affect your reflexes,
perceptions and judgement.The possibility of a serious or even fatal accident is
sharply increased when you drink or take drugs
and drive.Please don’t drink or take drugs and drive or allow
anyone to drive after drinking or taking drugs.Wa r n i n g !
Keep driver’s foot area clear at all times. Objects
stored in this area may impair pedal movement.

Te ch n i c a l

cluster displayPractical hints Car care Index Tires
Tread wear indicators (TWI) are required by law. These
indicators are located in six places on the tread
circumference and become visible at a tread depth of
approximately
1/16 in (1.5 mm), at which point the tire is
considered worn and should be replaced.
The tread wear indicator appears as a solid band across
the tread.Specified tire pressures must be maintained. This
applies particularly if the tires are subjected to high
loads (e.g. high speeds, heavy loads, high ambient
temperatures).
Wa r n i n g !
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 roadway.Inspect the tires and under the vehicle for possible
damage. If the vehicle or tires appear unsafe, have
it towed to the nearest Mercedes-Benz Center or
tire dealer for repairs.
Wa r n i n g !
Do not allow your tires to wear down too far. As
tread depth approaches
1/16 in (1.5 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.Wa r n i n g !
Do not drive with a flat tire. A flat tire affects the
ability to steer or brake the vehicle. You may 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.

275 Driving systems
Te ch n i c a l
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index Brake assist system (BAS)
The BAS is designed to maximize the vehicle’s braking
capability during emergency braking maneuvers by
having maximum power boost applied to the brakes
more quickly in emergency braking conditions than
might otherwise be afforded solely by the driver’s
braking style. This can help reduce braking distances
over what ordinary driving and braking style might do.
The BAS complements the antilock brake system (ABS).Applying the brakes very quickly results in maximum
BAS assistance.
To receive the benefit of the system you must apply
continuous full braking power during the stopping
sequence. Do not reduce brake pedal pressure.
Once the brake pedal is released, the BAS is deactivated.
If the BAS warning message is displayed in the
multifunction display, a malfunction has been detected
in the system. The brake system functions in the usual
manner, but without BAS.
With the ABS malfunctioning, the BAS is also switched
off.
If the BAS warning message is displayed in the
multifunction display, have the BAS checked at your
authorized Mercedes-Benz Center as soon as possible.
Wa r n i n g !
BAS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase
braking efficiency beyond that afforded by the
condition of the vehicle brakes and tires or the
traction afforded. The BAS cannot prevent
ac c id ent s, i nc l udi ng t hose resul tin g from exc es si ve
speed in turns, following another vehicle too
closely, or aquaplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The
capabilities of a BAS equipped vehicle must never
be exploited in a reckless or dangerous manner
which could jeopardize the user’s safety or the
safety of others.
