Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced
vehicle control. Your vehicle’s ABS will not
prevent this type of loss of control.iWhen you brake or stop, the transmis-
sion shifts down to a gear from which
you can easily accelerate or take off.

Canceling cruise control
There are several ways to cancel the cruise
control:
Step on the brake pedal.
The cruise control is canceled. The last
speed set is stored for later use.
or
Briefly push the cruise control lever in
direction of arrow3 (
page 261).
The cruise control is canceled. The last
speed set is stored for later use.
iOn u phil l or d ownhill gra de s, the cr uis e
control may not be able to maintain the
set speed. Once the grade eases, the
set speed will be resumed.
On downhill grades, the cruise control
maintains the set speed with braking
from the vehicle’s braking system.
In addition, on longer downhill grades
the automatic transmission* will auto-
matically downshift.
iVehicles with manual transmission:
If you depress the clutch pedal when
shifting into another gear, the engine
speed may increase.
Drive with sufficient engine speed.
Shift gears in a timely manner.
If possible, do not shift down more
than one gear.
iThe last stored speed is canceled when
you turn off the engine.

Vehicles with manual transmission:
you depress the clutch pedal for
longer than 6 seconds during shift-
ing into another gear.
Vehicles with automatic transmis-
sion*: you move the gear selector
lever to positionN while driving.
!Vehicles with automatic transmission*:
Moving gear selector lever to
positionN while driving also cancels
cruise control. However, the gear se-
lector lever should not be moved to
positionN while driving except to coast
when the vehicle is in danger of skid-
ding (e.g. on icy roads).iDepressing the accelerator pedal does
not deactivate the cruise control. After
brief acceleration (e.g. for passing), the
cruise control will resume the last
speed set.
iWhen you use the cruise control lever
to decelerate, the brake system will
automatically brake the vehicle if the
engine’s braking power does not brake
the vehicle sufficiently.

Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit)
after several seconds of transmission
which may not be long enough for the
integrated signal transmitter to pick up the
signal during programming. Similar to this
Canadian law, some U.S. gate operators
are designed to “time-out” in the same
manner.iSome garage door openers (or other
rolling code equipped devices) may
require you to press, hold for 2 seconds
and release the same signal transmit-
ter button a third time to complete the
training process.

296 OperationDriving instructionsDriving 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 oper-
ating temperature has been reached.
When starting off on a slippery surface, do
not allow a drive wheel to spin for an ex-
tended 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.
Parking
!Simultaneously depressing the acceler-
ator pedal and applying the brake re-
duces engine performance and causes
premature brake and drivetrain wear.
Warning!
G
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 selector lever to positionP
(manual transmission: first or reverse
gear).
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 and lock vehicle
when leaving.!Set the parking brake whenever park-
ing or leaving the vehicle. In addition,
place gear selector lever* in positionP
(manual transmission: move gearshift
lever to first or reverse gear).
In addition, when parking on hills, turn
front wheel towards the road curb.

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 gear selector lever* to positionN or
declutch in case of manual transmission.
Try to keep the vehicle under control by
corrective steering action.
