detailed information on operating, main-
taining and caring for your vehicle. The first 1000 miles (1500 km)
The more cautiously you treat your vehicle
during the break-in period, the more satis-
fied you will be with its performance later
on. You should therefore observe the fol-
lowing for the first 1000 miles (1500 km):
Drive at varying but moderate road and
Do not drive faster than 150 mph
Break in new tires for the first
100 miles (160 km), therefore avoid
high-speed cornering. Do not exceed a
speed of 125 mph (200 km/h).
Do not drive at engine speeds above
Try to avoid heavy load on the engine
(driving at full throttle) and driving at
high engine speeds (maximum of
of top speed of each gear) during this
Avoid accelerating by kick-down.
Change gears in good time.
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
Select C as the preferred shift program
(page 173) for the first 1000 miles
After 1000 miles (1500 km), you may grad-
ually bring the vehicle up to full road and
All of the above instructions also apply
when driving the first 1000 miles
(1500 km) after the engine or the rear dif-
ferential has been replaced.
iAlways obey applicable speed limits.

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.
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.

232 OperationDriving instructionsPower assistance
The brake system requires electrical energy
A malfunction in the vehicle’s power supply
or electrical system may impair brake sys-
tem operation and switch it into its emer-
gency operation mode. In such a case, the
red brake warning lamp (
page 300) and
warning messages (
page 307) in the in-
strument cluster come on while driving. To
brake, the driver must then apply signifi-
cantly greater brake pedal pressure and de-
press the pedal much further to obtain the
expected braking effect. If necessary, apply
full pressure to the brake pedal. Brakes are
only applied to the front wheels. Stopping
distance is increased! If there is a malfunc-
tion in the electrohydraulic brake system,
we recommend that the vehicle be trans-
ported with all wheels off the ground using
flatbed or appropriate wheel lift/dolly equip-
A tow bar must be used if circumstances do
not permit the use of the recommended
towing methods and the vehicle requires
towing with all four wheels on the ground.
Towing the vehicle with all four wheels on
the ground is only permissible for distances
up to 30 miles (50 km) and at a speed not to
exceed 30 mph (50 km/h). For more infor-
mation, see “Towing the vehicle”
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 ve-
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
Resting your foot on the brake pedal will
cause excessive and premature wear of the
It can also result in the brakes overheating
thereby significantly reducing their effec-
tiveness. It may not be possible to stop the
vehicle in sufficient time to avoid an acci-

After driving on wet or snow-covered
roads, you should apply your brakes firmly
before parking your vehicle. This produces
heat which serves to dry the brake disks.
If the parking brake is released and the red
brake warning lamp in the instrument clus-
ter stays on, there is a malfunction in the

technicians only. Contact an authorized

noise, you should occasionally test the
effectiveness of the brakes by applying
above-normal braking pressure at high
speeds. Please perform this braking
procedure three times. This will also
enhance the grip of the brake pads. If
the noise continuous, contact an au-
thorized Mercedes-Benz Center.
Make sure not to endanger any other road
users when carrying out these braking
maneuvers.!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.
Be certain to read and observe the warning
notices on brake pad replacement

234 OperationDriving instructionsAfter hard braking, it is advisable to drive
on for some time, rather than immediately
park, so 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
(page 303).When starting off on a slippery surface, do
not allow a drive wheel to spin for an
extended period with the ESP
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 pre-
vent overheating of the brakes and re-
duces 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 com-
bustible 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.
Pull the parking brake lever up as many
notches as possible.
Move the gear selector lever to
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.
