Driving safety systems
For more information, see “Practical Hints”
(page 365).Switching off the ESP
®
To improve the vehicle’s traction, turn off
the ESP
® in driving situations where it
would be advantageous to have the drive
wheels spin and thus cut into surfaces for
better grip such as:
when driving with snow chains
in deep snow
in sand or gravel
Warning!
G
The ESP
® cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase the traction afforded. The ESP
®
cannot prevent accidents, including those
resulting from excessive speed in turns, or
hydroplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The ca-
pabilities of an ESP
® equipped vehicle must
never be exploited in a reckless or danger-
ous manner which could jeopardize the us-
er’s safety or the safety of others.
iThe ESP
® will only function properly if
you use wheels of the recommended
tire size (page 439).
!Because of the ESP
®’s automatic oper-
ation, the engine must be turned off
(SmartKey in starter switch position0
or1) when
the parking brake is being tested on
a brake test dynamometer
the vehicle is being towed with the
front axle raised
Active braking action through the ESP
®
may otherwise seriously damage the
brake system.
Warning!
G
The ESP
® should not be switched off during
normal driving other than in the circum-
stances described below. Disabling of the
system will reduce vehicle stability in stan-
dard driving maneuvers.
Do not switch off the ESP
® when a spare
wheel with collapsible tire is mounted.

Manual transmission
Manual transmission
Manual transmission is standard equip-
ment on select models and not available
on all models.
For information on driving with a manual
transmission, see “Manual transmission”
(page 51).
Warning!
G
For vehicles equipped with a manual trans-
mission, getting out of your vehicle with the
gearshift lever not engaged in first or re-
verse gear and parking brake engaged is
dangerous.
Also, when parked on an incline, an engaged
first or reverse gear alone may not prevent
your vehicle from moving, possibly hitting
people or objects.
Always set the parking brake in addition to
engaging first or reverse gear (
page 59).
When parked on an incline, 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.
Warning!
G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Children
could move the gearshift lever, which could
result in an accident and/or serious injury.Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action.
This could result in drive wheel slip and re-
duced vehicle control. Your vehicle’s ABS
will not prevent this type of loss of control.

The current gear range/gear selector lever
position and program mode (
C/S) or
(
M/C/S) appear in the multifunction
display.When the gear selector lever is in
positionD, you can influence transmission
shifting by:
limiting the gear range
changing gears manually
Warning!
G
It is dangerous to shift the gear selector
lever out ofP orN if the engine speed is
higher than idle speed. If your foot is not
firmly on the brake pedal, the vehicle could
accelerate quickly forward or reverse. You
could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and when
your right foot is firmly on the brake pedal.
!Allow engine to warm up under low
load use. Do not place full load on the
engine until the operating temperature
has been reached.
Shift into reverse gearR or parking
positionP only when the vehicle is
stopped.
Avoid spinning of a drive wheel for an
extended period when driving off on
slippery road surfaces. This may cause
serious damage to the drivetrain which
is not covered by the Mercedes-Benz
Limited Warranty.

ì
Park position
Gear selector lever position
when the vehicle is parked. Place
gear selector lever in positionP
only when vehicle is stopped.
The park position is not intended
to serve as a brake when the
vehicle is parked. Rather, the
driver should always set the
parking brake in addition to
placing the gear selector lever in
positionP to secure the vehicle.
EffectThe SmartKey can only be
removed from the starter switch
with the gear selector lever in
positionP. With the SmartKey
removed, the gear selector lever
is locked in positionP.
If the vehicle’s electrical system
is malfunctioning, the gear
selector lever could remain
locked in positionP
(page 396).
í
Reverse gear
Place gear selector lever in
positionR only when vehicle is
stopped.
Effect

No power is transmitted from the
engine to the drive axle. When
the brakes are released, the
vehicle can be moved freely
(pushed or towed).
To avoid damage to the trans-
mission, never engageN while
driving.
If the ESP
® is deactivated or
malfunctioning:
Move gear selector lever toN
only if the vehicle is in danger of
skidding, e.g. on icy roads.

Gear ranges
With the gear selector lever in positionD
and driving in the automatic shift
programC orS (
page 163), you can
select a gear range for the automatic
transmission to operate within:
Gear selector lever (page 164):
You can limit the gear range by pressing
the gear selector lever to the left (D-), and
reverse the gear range limit by pressing
the gear selector lever to the right (D+).
Steering wheel gearshift control
(
page 165):
You can limit the gear range by pressing
the respective downshift button on the
steering wheel gearshift control, and
reverse the gear range limit by pressing
the respective upshift button on the
steering wheel gearshift control.
!Coasting the vehicle, or driving for any
other reason with gear selector lever
inN can result in transmission damage
that is not covered by the
Mercedes-Benz Limited Warranty.Warning!
G
Getting out of your vehicle with the gear
selector lever not fully engaged in positionP
is dangerous. Also, positionP alone is not
intended to or capable of preventing your
vehicle from moving, possibly hitting people
or objects.
Always set the parking brake in addition to
shifting to positionP (
page 52). When
parked on an incline, turn the 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.
Warning!
G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Children
could move the gear selector lever from
positionP, which could result in an accident
and/or serious personal injury.

Accelerator position
Your driving style influences the
transmission’s shifting behavior:
Less throttle Earlier upshifting
More throttle Later upshifting
Kickdown
Use kickdown when you want maximum
acceleration.
Press the accelerator past the point of
resistance.
The transmission shifts into a lower
gear.
Ease on the accelerator when you have
reached the desired speed.
The transmission shifts up again.Stopping
When you stop briefly, e.g. at traffic lights:
Leave the transmission in gear.
Hold the vehicle with the brake.
When you stop longer with the engine
idling and/or on a hill:
Set the parking brake.
Move the gear selector lever to
positionP.
Maneuvering
When you maneuver in tight areas,
e.g. when pulling into a parking space:
Control the vehicle speed by gradually
releasing the brakes.
Accelerate gently.
Never abruptly step on the accelerator.Working on the vehicle
Warning!
G
When working on the vehicle, set the
parking brake and move gear selector lever
to positionP. Otherwise the vehicle could
roll away.

!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

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.
