LOW RANGE – ESP
During off-road driving, a special low range
system for the ESP is operational with
transmission in LOW RANGE mode
(page 125).
In the LOW RANGE mode, the ESP ope-
rates in a traction improving fashion spe-
cifically adapted for off-road driving. At
speeds below 27 mph (45 km / h), the ESP
assists in over- / understeering, thus im-
proving vehicle traction.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
when driving off-road
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, fol-
lowing another vehicle too closely, or hydro-
planing. Only a safe, attentive, and skillful
driver can prevent accidents. The capabili-
ties of an ESP equipped vehicle must never
be exploited in a reckless or dangerous
manner which could jeopardize the user’s
safety or the safety of others.
!Because of the ESP’s automatic opera-
tion, 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.
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.

The switch is located in the upper center
console.ESP on / off switch
Press upper half of the ESP switch.
The 4-ETS / ESP warning lampv in
the speedometer comes on.
The ESP is deactivated.
If one or more drive wheels are spinning,
the 4-ETS / ESP warning lampv in the
speedometer flashes, regardless of the
speed.Traction control brakes a spinning wheel
even when the ESP is deactivated.
The ESP always operates when you are
braking, even when it has been deactiva-
ted.
Switching on the ESP
Press lower half of the ESP switch until
the 4-ETS / ESP warning lampv in
the speedometer goes out.
You are now again in normal driving
mode.
For more information, see “Practical hints”
(
page 241).
!Avoid spinning of a drive wheel for an
extended period with the ESP switched
off. This may cause serious damage to
the drivetrain which is not covered by
the Mercedes-Benz Limited Warranty.iTurn ESP on immediately if the afore-
mentioned circumstances do not apply
anymore.
Warning!
G
When the 4-ETS / ESP warning lampv is
illuminated continuously, the ESP is
switched off.
Adapt your speed and driving to the prevail-
ing road conditions and to the non-operating
status of the ESP.

Locking and unlocking
Automatic central locking
The doors and the liftgate automatically
lock when the ignition is switched on and
the left front wheel turns at vehicle speeds
of approximately 9mph (15km/h) or
more.
If one of the front doors is then opened
from the inside, the vehicle is unlocked
centrally unless only the driver's door was
previously unlocked.Information on towing the vehicle can be
found in the “Practical hints” section
(
page 241).
The switch is located on the lower center
console.

Memory function*
With the memory button you can store up
to three different settings for the driver-
and passenger seat.
Together with the driver’s seat you can
store the exterior rear view mirrors.
For the front passenger seat you can store
the seat position.
Storing exterior rear view mirror parking position
For easier parking, you can adjust the pas-
senger-side exterior rear view mirror so
that you can see the right rear wheel as
soon as you engage reverse gearR.For information on activating the parking
position feature, see “Activating exterior
rear view mirror parking position”
(
page 127).

2Memory button
!Prior to operating the vehicle the driver
should check and adjust the seat
height, seat position fore and aft, and
seat backrest angle if necessary, to en-
sure adequate control, reach and com-
fort. The head restraint should also be
adjusted for proper height. See also the
section on airbags (
page 59) for
proper seat positioning.
In addition, adjust the steering wheel to
ensure adequate control, reach, opera-
tion and comfort. Both the inside and
outside rear view mirrors should be ad-
justed for adequate rear vision.
Fasten seat belts. Infants and small
children should be seated in a properly
secured restraint system that complies
with U.S. Federal Motor Vehicle Safety
Standard 213 and 225 and Canadian
Motor Vehicle Safety Standard 213 and
210.2.
Warning!
G
Do not activate the memory function while
driving. Activating the memory function
while driving could cause the driver to lose
control of the vehicle.

120 Controls in detailAutomatic transmissionOne-touch gearshifting
Even with an automatic transmission you
can change the gears manually when the
gear selector lever is in positionD.
Downshifting
Briefly press the gear selector lever to
the left in the D–direction.
The transmission will shift from the current
gear to the next lower gear. This action
simultaneously limits the gear range of the
transmission (
page 121).Upshifting
Briefly press the gear selector lever to
the right in the D+direction.
The transmission will shift from the current
gear to the next higher gear as permitted
by the shift program. This action simul-
taneously extends the gear range of the
transmission.Canceling gear range limit
Press and hold the gear selector lever
in the D+direction until D reappears in
the tachometer display.
The transmission will shift from the current
gear range directly to gear rangeD.
Shifting into optimal gear range
Press and hold the gear selector lever
in the D– direction.
The transmission will automatically select
the gear range suited for optimal
acceleration and deceleration. This will
involve shifting down one or more gears.
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.
iTo avoid overrevving the engine when
the gear selector lever is moved to
the D– direction, the transmission will
not shift to a lower gear if the engine’s
max. speed would be exceeded.

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.
!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 53).
When parked on an incline, turn the front
wheels towards the road curb.
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.Warning!
G
When leaving the vehicle, always remove the
key from the steering lock, 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.
