switch. The vehicle cannot be steered when
the SmartKey is removed.Warning!
G
With the engine not running, there is no
power assistance for the brake and steering
system. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the
vehicle.
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.

When leaving the vehicle, always remove the
SmartKey from the starter switch and lock
the vehicle. Do not leave children unattend-
ed in the vehicle, or with access to an un-
locked vehicle. Children could release the
parking brake and/or move the gear selec-
tor lever from positionP, either of which
could result in an accident and/or serious
injury.
Warning!
G
Getting out of your vehicle with the gear se-
lector lever not fully engaged in positionP is
dangerous. Also, when parked on an incline,
positionP alone may not prevent your vehi-
cle from moving, possibly hitting people or
objects.
Always set the parking brake in addition to
shifting to positionP (manual transmission:
first or reverse gear).
When parked on an incline, turn front wheel
towards the road curb.

(page 44).
Allow the retractor to completely
rewind the seat belt by guiding the
latch plate.

After exiting the vehicle, press the lock
button‹ on the SmartKey
(page 32).
All turn signal lamps flash three times.
The locking knobs in the doors move
down.
For more information, see “Locking and
unlocking” (
page 88).
iAlways set the parking brake in addi-
tion to shifting to positionP (manual
transmission: first or reverse gear).
On steep slopes, turn the front wheels
towards the road curb. iVehicles with automatic transmission:
The SmartKey can only be removed
from the starter switch with the gear
selector lever in positionP.

keep hands and fingers away from the door
openings when closing the doors. Be espe-
cially careful when small children are
around.
Before closing doors, make sure there is no
possibility of someone getting caught in a
door during closing.
Warning!
G
When leaving the vehicle, always remove the
SmartKey from the starter switch, and lock
your vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Unsupervised use of vehi-
cle equipment may cause an accident
and/or serious personal injury.

80 Safety and SecurityDriving safety systems
For more information, see “Practical hints”
(page 306) and (
page 312).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:


starting out on slippery surfaces and in
deep snow in conjunction with snow
chains


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
capabilities of an ESP equipped vehicle must
never be exploited in a reckless or danger-
ous manner which could jeopardize the
user’s safety or the safety of others.iThe ESP will only function properly if
you use wheels of the recommended
tire size (
page 380).
!Vehicles without 4MATIC:
Because of the ESP’s automatic
operation, the engine must be shut 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.
For information on vehicles with
4MATIC, see “Four wheel electronic
traction system (4MATIC) with the
ESP” (
page 82).
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.!Turn on the ESP immediately if the
aforementioned circumstances do not
apply anymore.

82 Safety and SecurityDriving safety systemsFour wheel electronic traction system (4MATIC) with the ESP
Models with all-wheel-drive only.
The 4MATIC improves vehicle’s ability to
use available traction, e.g. during winter
operation in mountains under snowy
conditions, by applying power to all four
wheels.Warning!
G
If you see the ESP warning lampv flash-
ing in the speedometer, proceed as follows:

While driving off, apply as little throttle
as possible


While driving, ease up on the accelera-
tor


Adapt your speed and driving style to
the prevailing road conditions
Failure to observe these guidelines could
cause the vehicle to skid.
The ESP cannot prevent accidents resulting
from excessive speed.
!Do not tow with one axle raised.
Otherwise the transfer case can be
damaged, which is not covered by the
Mercedes-Benz Limited Warranty.!Performance testing must only be con-
ducted on a two-axle dynamometer.
Otherwise the transfer case can be
damaged, which is not covered by the
Mercedes-Benz Limited Warranty.
!Because of the ESP’s automatic
operation, the engine must be shut off
(SmartKey in starter switch position0
or1) when the parking brake is being
tested on a brake test dynamometer
Active braking action through ESP may
otherwise seriously damage the front
or rear axle brake system.
Operational tests with the engine
running can only be conducted on a
two-axle dynamometer.iAt highly demanding operating condi-
tions, the electronic traction system
may temporarily switch off to prevent
overheating of the drive wheel brakes.

normally.

154 Controls in detailManual transmissionManual transmission is standard
equipment on select models and not
available on all models.
For information on driving with a manual
transmission, see “Manual transmission”
(page 46).
Warning!
G
For vehicles equipped with a manual trans-
mission, getting out of your vehicle with the
gearshift lever not engaged in first or
reverse 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 54).
When parked on an incline, 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.
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 reduced
vehicle control. Your vehicle’s ABS will not
prevent this type of loss of control.
