280 OperationIn the “Operation” section you will find
detailed information on operating, main-
taining and caring for your vehicle.The first 1 000 miles (1 500 km)
The more cautiously you treat your vehicle
during the break-in period, the more satis-
fied you will be with its performance later
Drive your vehicle during the first
1 000 miles (1 500 km) at varying but
moderate vehicle and engine speeds.
During this period, avoid heavy loads
(full throttle driving) and excessive
engine speeds (no more than
maximum rpm in each gear).
Shift gears in a timely manner.
Avoid accelerating by kick-down.
Do not attempt to slow the vehicle
down by shifting to a lower gear using
the gear selector lever.
Select positions3,2 or1 only when
driving at moderate speeds (for hill

(page 164) for the first 1 000 miles
(1 500 km).After 1 000 miles (1 500 km) you may
gradually increase vehicle and engine
speeds to the permissible maximum.
All of the above instructions, as may apply
to your vehicle type, also apply when
driving the first 1 000 miles (1 500 km)
after the engine or the rear differential has

During the first 1 000 miles
(1 500 km), do not exceed a speed
of 85 mph (140 km/h).
During this period, avoid engine
speeds above 4 500 rpm in each

Drive sensibly – save fuel
Fuel consumption, to a great extent,
depends on driving habits and operating
To save fuel you should:
Keep tires at the recommended tire
Remove unnecessary loads.
Remove roof rack when not in use.
Allow engine to warm up under low
Avoid frequent acceleration and decel-
Have all maintenance work performed
at the intervals specified in the
Maintenance Booklet and as required
by the maintenance service display.
Contact an authorized Mercedes-Benz
Fuel consumption is also increased by
driving in cold weather, in stop-and-go
traffic, on short trips and in hilly area.
Drinking and driving
Drinking and driving and/or taking drugs
and driving are very dangerous combina-
tions. Even a small amount of alcohol or
drugs can affect your reflexes, perceptions
The possibility of a serious or even fatal
accident are greatly increased when you
drink or take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
Keep driver’s foot area clear at all times.
Objects stored in this area may impair pedal
With the engine not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the

driving on wet road surfaces (particularly
salted roads), it is advisable to brake the
vehicle with considerable force prior to
parking. The heat generated serves to dry
If your brake system is normally only
subject to moderate loads, you should
occasionally test the effectiveness of the
brakes by applying above-normal braking
pressure at higher speeds. This will also
enhance the grip of the brake pads.
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 fluid in the

immediately. Contact an authorized
All checks and service work on the brake
system should be carried out by qualified
technicians only. Contact an authorized
Only install brake pads and brake fluid

After driving in heavy rain for some time
without applying the brakes or through wa-
ter 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 ef-
fect. Maintain a safe distance from vehicles

cause excessive and premature wear of the

thereby significantly reducing their effec-
tiveness. It may not be possible to stop the

road users when you apply the brakes.
Refer to the description of the Brake
Assist System (BAS) (
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.
Page 284 from 474
After hard braking, it is advisable to drive
on for some time, rather than immediately
parking, so that the air stream will cool
down the brakes faster.Driving off
Apply the 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 a drive wheel to spin for an
extended period with the ESP switched off.
Doing so may cause serious damage to the
drivetrain which is not covered by the
Mercedes-Benz Limited Warranty.
!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.
!Simultaneously depressing the
accelerator pedal and applying the
brake reduces engine performance and
causes premature brake and drivetrain
wear.!Set the parking brake whenever park-
ing or leaving the vehicle. In addition,
move gear selector lever to positionP

When parking on hills, always turn front
wheels towards the road curb.
Do not park this vehicle in areas where
combustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
To reduce the risk of personal injury as a re-
sult of vehicle movement, before turning off
the engine and leaving the vehicle always:
Keep right foot on brake pedal.
Firmly depress parking brake pedal.
Move the gear selector lever to
positionP (manual transmission: first or
Slowly release brake pedal.
When parked on an incline, turn front
wheels towards the road curb.
Turn the SmartKey in the starter switch
to position0 and remove the SmartKey
from the starter switch.
Take the SmartKey with you and lock
the vehicle when leaving.

284 OperationDriving instructionsTires
Treadwear 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
in (1.6 mm), at which
point the tire is considered worn and
should be replaced.The treadwear indicator appears as a solid
band across the tread.
Specified tire inflation pressures must be
maintained. This applies particularly if the
tires are subjected to high loads (e.g. high
speeds, heavy loads, high ambient temper-
Depending on the depth of the water layer
on the road, hydroplaning may occur, even
at low speeds and with new tires. Reduce
vehicle speed, avoid track grooves in the
road and apply brakes cautiously in the
If you feel a sudden significant vibration or

Inspect the tires and the vehicle underbody
for possible damage. If the vehicle or tires
appear unsafe, have it towed to the nearest

Although the applicable federal motor
vehicle safety laws consider a tire to be
worn when the treadwear indicators (TWI)
become visible at approximately
(1.6 mm), we recommend that you do not
allow your tires to wear down to that level.
As tread depth approaches

Depending upon the weather and/or road
surface (conditions), the tire traction varies
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.
