93 Safety and Security
Driving safety systems
When you switch off the ESP®

the ESP® does not stabilize the vehicle

the engine output is not limited, which
allows the drive wheels to spin and
thus cut into surfaces for better grip

the traction control will still apply the
brakes to a spinning wheel

the ESP® continues to operate when
you are braking

you cannot activate the cruise control

the cruise control switches off if
currently activatedThe ESP
® switch is located on the center
console.
1ESP
® switch
With the engine running, press ESP®
switch1 until the ESP® warning
lampv in the instrument cluster
comes on.
The ESP
® is switched off.
Switching on the ESP®
Press ESP® switch1 until the ESP®
warning lampv in the instrument
cluster goes out.
You are now again in normal driving
mode with ESP
® switched on.
iWhen the ESP® is switched off and one or
more drive wheels are spinning, the ESP® warn-
ing lampv in the instrument cluster flashes.
However, the ESP
® will then not stabilize the ve-
hicle.
Warning!G
When the ESP® warning lampv is
illuminated continuously, the ESP® is
switched off or is not operational due to a
malfunction. Vehicle stability in standard
driving maneuvers reduces.
Adapt your speed and driving to the prevail-
ing road conditions and to the non-operating
status of the ESP
®.
!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.

Driving systems
The driving systems of your vehicle are de-
scribed on the following pages:

Cruise control, with which the vehicle
can maintain a preset speed.

Parktronic* (Canada only), which
serves as a parking assistant.
For information on the BAS, ABS, and
ESP
®, see “Driving safety systems”
(
page 88).
Cruise control
Cruise control automatically maintains the
speed you set for your vehicle.
Use of cruise control is recommended for
driving at a constant speed for extended
periods of time.
You can set or resume cruise control at any
speed over 20 mph (30 km/h).
The cruise control function is operated by
means of the cruise control lever.
The cruise control lever is the uppermost
lever on the left-hand side of the steering
column (
page 24).
Warning!G
Cruise control is a convenience system de-
signed to assist the driver during vehicle op-
eration. The driver is and must always
remain responsible for the vehicle’s speed
and for safe brake operation.
Only use cruise control if the road, traffic
and weather conditions make it advisable to
travel at a steady speed.

The use of cruise control can be danger-
ous on winding roads or in heavy traffic
because conditions do not allow safe
driving at a steady speed.

The use of cruise control can be danger-
ous on slippery roads. Rapid changes in
tire traction can result in wheel spin and
loss of control.

Deactivate cruise control when driving
in fog.
The “Resume” function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.

Setting current speed
Accelerate or decelerate to the desired
speed.
Briefly lift1 or depress2 the cruise
control lever.
The current speed is set.
Remove your foot from the accelerator
pedal.
Cruise control is activated.The selected speed appears in the multi-
function display for approximately five sec-
onds, and the corresponding speedometer
segments from the selected speed to the
vehicle maximum speed are illuminated.
Warning!G
Cruise control brakes automatically so that
the set speed is not exceeded. The brake
pedal depresses when the cruise control en-
gages the brakes.
Keep driver’s foot area clear at all times, in-
cluding the area under the brake pedal. Ob-
jects stored in this area may impair pedal
movement which could interfere with the
braking ability of the cruise control system.
Do not place your foot under the brake pedal
- your foot could become caught.
Keep in mind that cruise control is a conve-
nience system designed to assist the driver
during vehicle operation. The driver is and
must always remain responsible for the ve-
hicle’s speed and for safe brake operation.
iOn uphill or downhill grades, cruise 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 will hold
the set speed with braking from the vehicle’s
brake system.
In addition, on longer downhill grades the auto-
matic transmission will automatically downshift.

Canceling cruise control
There are several ways to cancel cruise
control:
Step on the brake pedal.
Cruise control is canceled. The last
speed set is stored for later use.
or
Briefly push the cruise control lever to
position3.

you move the gear selector lever in
positionN while driving.
The segments in the multifunction display
(
page 254) go out, and an acoustic warning
sounds.
!Moving gear selector lever to positionN
while driving also cancels cruise control. Howev-
er, the gear selector lever should not be moved
to positionN while driving except to coast when
the vehicle is in danger of skidding (e.g. on icy
roads).
iDepressing the accelerator pedal does not
deactivate cruise control. After brief accelera-
tion (e.g. for passing), cruise control will resume
the last speed set.

rection of arrow2 and hold it down
until the desired speed is reached.
Release the cruise control lever.
The new speed is set.Fine adjustment in 1 mph

Slower
Briefly tip cruise control lever in the di-
rection of arrow2.Setting to last stored speed
(“Resume” function)
Briefly push cruise control lever in the
direction of arrow4.
The cruise control resumes the last set
speed.
Remove your foot from the accelerator
pedal.
The selected speed appears in the multi-
function display for approximately five sec-
onds, and the corresponding speedometer
segments from the selected speed to the
vehicle maximum speed are illuminated
(
page 254).
iWhen you use the cruise control lever to de-
celerate, the brake system will automatically
brake the vehicle if the engine’s braking power
does not brake the vehicle sufficiently.
Warning!G
The speed stored in memory should only be
set again if prevailing road conditions per-
mit. Possible acceleration or deceleration
differences arising from returning to the pre-
set speed could cause an accident and/or
serious injury to you and others.

299 Operation
Driving instructions
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 position N. Try
to keep the vehicle under control by cor-
rective steering action.Road salts and chemicals can adversely af-
fect braking efficiency. Increased pedal
force may become necessary to produce
the normal braking effect.
Depressing the brake pedal periodically
when traveling at length on salt-strewn
roads can bring road-salt-impaired braking
efficiency back to normal.
If the vehicle is parked after being driven
on salt-treated roads, the braking efficien-
cy should be tested as soon as possible af-
ter driving is resumed.
For more information, see “Winter driving”
(
page 341).
iFor information on driving with snow chains,
see “Snow chains” (
page 342).
Warning!G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of control loss.
Warning!G
Make sure not to endanger any other road
users when carrying out these braking ma-
neuvers.
Warning!G
If the vehicle becomes stuck in snow, make
sure snow is kept clear of the exhaust pipe
and from around the vehicle with the engine
running. Otherwise, deadly carbon monox-
ide (CO) gases may enter vehicle interior re-
sulting in unconsciousness and death.
To assure sufficient fresh air ventilation,
open a window slightly on the side of the ve-
hicle not facing the wind.
Warning!G
The outside temperature indicator is not de-
signed to serve as an ice-warning device and
is therefore unsuitable for that purpose. In-
dicated temperatures just above the freez-
ing point do not guarantee that the road
surface is free of ice.
