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
weather, in stop-and-go traffic, on short trips and in hilly
country.Drinking and driving
Pedals
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.

Power assistance
BrakesThe condition of the parking brake system is checked
each time the vehicle is in the shop for the required
maintenance service.
If the parking brake is released and the brake warning
lamp in the instrument cluster stays on, the brake fluid
level in the reservoir is too low.
Brake pad wear or a leak in the system may be the
reason for low brake f luid in the reservoir.
Have the brake system inspected at an authorized
Mercedes-Benz Center immediately.
All checks and service work on the brake system should
be carried out by an authorized Mercedes-Benz Center.
Install only brake pads and brake fluid recommended by
Mercedes-Benz.
Wa r n i n g !
When the engine is not running, the brake and
steering systems are without power assistance.
Under these circumstances, a much greater effort is
necessary to stop or steer the vehicle.Wa r n i n g !
After driving in heavy rain for some time without
applying the brakes or through water deep enough
to wet brake components, the first braking action
may be somewhat reduced and increased pedal
pressure may be necessary to obtain expected
braking effect. Be sure to maintain a safe distance
from vehicles in front.Resting your foot on the brake pedal will cause
excessive and premature wear of the brake pads.It can also result in the brakes overheating thereby
significantly reducing their effectiveness. It may
not be possible to stop the vehicle in sufficient time
to avoid an accident.
Wa r n i n g !
If other than recommended brake pads are
installed, or other than recommended brake fluid
is used, the braking properties of the vehicle can be
degraded to an extent that safe braking is
substantially impaired. This could result in an
accident.

cluster displayPractical hints Car care Index Caution!
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 brake pad wear.
After hard braking, it is advisable to drive on for some
time, rather than immediately parking, so the air stream
will cool down the brakes faster.Driving off
Apply the service brakes to test them briefly after
driving off. Perform this procedure only when the road
is clear of other traffic.
Warm up the engine smoothly. Do not place full load on
the engine until the operating temperature has been
reached.
When starting off on a slippery surface, do not allow one
drive wheel to spin for an extended period with the ESP
switched off. Doing so may cause serious damage to the
drive train which is not covered by the Mercedes-Benz
Limited Warranty.

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.
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 f lashers, 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.

Important!
Use of snow chains is not permissible with tire sizes
245 / 45 R18 or 275 / 40 R18.
Winter driving instructions
The most important rule for slippery or icy roads is to
drive sensibly and to avoid abrupt acceleration, braking
and steering maneuvers. Do not use the cruise control
system under such conditions.
When the vehicle is in danger of skidding, move
selector lever to position “N”. Try to keep the vehicle
under control by corrective steering action.
Road salts and chemicals can adversely affect braking
efficiency. Increased pedal force may become necessary
to produce the normal brake effect. We therefore
recommend depressing the brake pedal periodically
when traveling at length on salt-strewn roads. This can
bring road salt impaired braking efficiency back to
normal. A prerequisite is, however, that this be done
without endangering other drivers on the road.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 while observing the
safety rules in the previous paragraph.
Wa r n i n g !
If the vehicle becomes stuck in snow, make sure
that snow is kept clear of the exhaust pipe and
from around the vehicle with engine running.
Otherwise, deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in unconsciousness
and death.To assure sufficient fresh air ventilation, open a
window slightly on the side of the vehicle not
facing the wind.

Deep water
Caution!
Do not drive through flooded areas or water of unknown
depth.
If you must drive through deep water, drive slowly to
prevent water from entering the engine compartment or
passenger compartment, being ingested by the air
intake, possibly causing damage to electrical
components or wiring, to engine or transmission that is
not covered by the Mercedes-Benz Limited Warranty.
Passenger compartmentTraveling abroad
Abroad, there is a widely-spread Mercedes-Benz service
network at your disposal. If you plan to travel into areas
which are not listed in the index of your Mercedes-Benz
Center directory, you should request pertinent
information from your authorized Mercedes-Benz
Center.
Wa r n i n g !
Always fasten items being carried as securely as
possible.In an accident, during hard braking or sudden
maneuvers, loose items will be thrown around
inside the vehicle, and cause injury to vehicle
occupants unless the items are securely fastened in
the vehicle.The trunk is the preferred place to carry objects.

•For a more precise setting the speed can be
increased in increments of 1 mph (Canada: 1 km/h)
by briefly pulling the control lever in direction (4).
Caution!
If the driver’s foot is not fully removed from the
accelerator pedal, the Distronic control system will be
overridden and it will not regulate the preset vehicle
speed and following distance. The vehicle speed and
following distance will be determined only by the
accelerator pedal position.Invalid attempts to activate
The multifunction display will show “–––” during
invalid attempts to activate Distronic:
•below a speed of approximately 25 mph
(Canada: 30 km/h),
•while the electronic stability program (ESP) is
switched off – ESP warning lampv in
speedometer dial is illuminated, see page 114,
•by moving the distronic control lever in “RESUME”
direction (4) when no speed is stored in memory,
•during the initialization and self-test phase after the
engine is started – this can take up to 2 minutes,
•while depressing the service brake pedal,
•while the parking brake is set – check ;warning
lamp (Canada: !) in instrument cluster, see
page 114,
•with the gear selector lever in position “P”, “R”
or “N” – check gear range indicator display in
instrument cluster, see page 114.
Wa r n i n g !
Distronic brakes (up to 20% of vehicle braking
power) the vehicle to restore the preset distance or
to maintain the speed. The brake pedal is
automatically retracted as this happens.Keep driver’s foot area clear at all times, including
the area under the brake pedal. Objects stored in
this area may impair pedal movement which could
interfere with the braking ability of the Distronic
system.Do not place your foot under the brake pedal – your
foot could become caught.

Driving with Distronic activated
With the electronic key in starter switch position 2, the
distance warning lamp l in the speedometer dial comes
on and goes out with the engine running.
If the distance sensor detects a slower vehicle moving in
front, your vehicle speed will be reduced by
deceleration and braking of up to 20% of the vehicle
braking capacity, so that you follow the vehicle ahead at
the preset distance, see page 268. Segments in the
speedometer illuminate to indicate the speed range from the speed of the vehicle in front up to your
vehicle’s selected speed. See also page 269 for notes on
the multifunction displays.
