Electronic stability program (ESP)
The ESP enhances directional control and reduces
driving wheel spin of the vehicle under various driving
conditions.
Over/understeering of the vehicle is counteracted by
applying brakes to the appropriate wheel to create a
countervailing vehicle movement. Engine torque is also
limited. The ESP warning lamp, located in the
speedometer dial, starts to flash when ESP is in
operation.Important!
If the ESP warning lampv flashes:
•During take-off apply as little throttle as possible.
•While driving ease up on the accelerator.
•Adapt your speed and driving to the prevailing road
conditions.
•Do not switch off the ESP.
Caution!
If the vehicle is towed with the front axle raised (see
page 357, towing the vehicle), the engine must be shut
off (electronic key in starter switch position 0 or 1).
Otherwise, the ESP will immediately be engaged and
will apply the rear wheel brakes.
Wa r n i n g !
ESP cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded. The ESP cannot prevent
ac c id ent s, i nc l udi ng t hose resul tin g from exc es si ve
speed in turns, or aquaplaning. 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 dangerous
manner which could jeopardize the user’s safety or
the safety of others.

cluster displayPractical hints Car care Index Notes:
The yellow ESP warning lampv in the speedometer
dial comes on with the electronic key in starter switch
position 2. It should go out with the engine running.
If the ESP warning message is displayed, a malfunction
has been detected in the system. Only partial engine
output will be available.
Have the ESP checked at your authorized
Mercedes-Benz Center as soon as possible.
For ESP warning message, see page 309.
With the ABS malfunctioning, the ESP and the BAS is
also switched off.
Driving the vehicle with varied size tires will cause the
wheels to rotate at different speeds, therefore the ESP
may activate (yellow ESP warning lamp in speedometer
d ial com es on ). For t his reas on, all wheels, in cludin g t he
spare wheel, must have the same tire size. When testing the parking brake on a brake test
dynamometer, the engine must be shut off. Otherwise,
the ESP will immediately be engaged and will apply the
rear wheel brakes.
In winter operation, the maximum effectiveness of the
ESP is only achieved with Mercedes-Benz recommended
M+S rated radial-ply tires and/or snow chains.
Synchronizing ESP
If the power supply was interrupted (battery
disconnected or empty), the ESP warning message may
be displayed with the engine running.
Turn steering wheel completely to the left and then to
the right. The ESP warning message should go out.

ESP control switch
ESP control switch located on center console.
1Press to switch ESP off
ESP warning lampv, located in speedometer
dial, comes on.
2Press to switch ESP on
ESP warning lampv, located in speedometer
dial, goes out.To improve the vehicle’s traction when driving with
sn ow chain s, or startin g of f in d eep sn ow, san d o r grave l,
switch off ESP by pressing the upper half (1) of the ESP
switch. The ESP warning lampv, located in the
speedometer dial, is continuously illuminated.
With the ESP system switched off, the engine torque
reduction feature is cancelled. Therefore, the enhanced
vehicle stability offered by ESP is unavailable.
Adapt your speed and driving to the prevailing road
conditions.
A portion of the ESP system remains active, even with
the switch in the OFF position.
If one drive wheel loses traction and begins to spin, the
brake is applied until the wheel regains sufficient
traction. The traction control engages at vehicle speeds
up to approximately 24 mph (40 km/h), and switches off
at 50 mph (80 km/h).
Wa r n i n g !
When the ESP warning lamp is illuminated
continuously, the ESP is switched off. Ad apt your s peed an d d ri vi n g to the prevai li ng road
conditions.

Avoid spinning of one drive wheel. This may cause
serious damage to the drive train which is not covered
by the Mercedes-Benz Limited Warranty.
The ESP warning lamp, located in the speedometer dial,
starts to flash at any vehicle speed as soon as the tires
lose traction and the wheels begin to spin.
To return to the enhanced vehicle stability offered by
ESP: press lower half (2) of the switch (the ESP warning
lamp in the speedometer dial goes out).Vehicles with Distronic (DTR):
With the ESP switched off, the Distronic could not be
switched on. See page 259 for activation of Distronic.
Important!
If the ESP warning lamp flashes:
•during take-off, apply as little throttle as possible,
•while driving, ease up on the accelerator.
Wa r n i n g !
ESP should not be switched off during normal
driving other than in circumstances described
above. Disabling of the system will reduce vehicle
stability in standard driving maneuvers.

Parking assist (Parktronic)
(optional)
The Parktronic system assists the driver during parking
maneuvers. It visually and audibly indicates the relative
distance between the vehicle and an obstacle.
The front area of the vehicle is monitored when driving
forward. When reversing or with the gear selector lever
in position “N”, the front as well as the rear areas are
monitored.
With the electronic key in starter switch position 2,
Parktronic engages automatically at speeds up to
approximately 10 mph (15 km/h) and deactivates during
higher speeds.
Parktronic can be switched off by a control switch
located in the center console. It engages automatically
again when starting the engine.
See page 290 for parktronic switch.
Wa r n i n g !
Parktronic is a supplemental system. It is not
i nten ded to nor d oes i t repla c e the n eed for extrem e
care. The responsibility during parking and other
critical maneuvers rests always with the driver.Special attention must be paid to objects having
smooth surfaces or low silhouettes (e.g. trailer
couplings, painted posts, or street curbs). Such
objects may not be detected by the system and can
damage the vehicle.The operational function of the Parktronic can be
affected by dirty sensors, especially at times of
snow and ice. See page 384 for notes on cleaning
the parktronic system sensors.Interference caused by other ultrasonic signals
(e.g. working jackhammers or the air brakes of
trucks) can cause the system to send erratic
indications, and should be taken into
consideration.
