Driving safety systems
For more information, see the “Practical
hints” section (
page 345) and
(
page 363).Electronic traction system
The electronic traction system is a
component of ESP
®.
The electronic traction system improves
the vehicle’s ability to utilize available
traction, especially under slippery road
conditions by applying the brakes to a
spinning wheel.
Except CLS 63 AMG:
When you switch off the ESP
®, the
electronic traction system is still enabled.
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.
!The ESP® will only function properly if you
use wheels of the recommended tire size
(
page 438).
!Because the ESP® operates automatically,
the engine and the ignition must be shut off
(SmartKey in starter switch position0 or1 or
KEYLESS-GO start/stop button* in 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 oth-
erwise seriously damage the brake system.
Warning!G
If you are driving too fast, the electronic
traction system cannot reduce the risk of an
accident.
The electronic traction system cannot pre-
vent the natural laws of physics from acting
on the vehicle.

The current gear selector lever position
appears in the multifunction display.
1Current gear selector lever positionEffect
ìPark position
Gear selector lever position
when the vehicle is parked. Place
gear selector lever in park
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 park positionP to secure the
vehicle.
Effect
The SmartKey can only be
removed from the starter switch
with the gear selector lever in
park positionP. With the
SmartKey removed, the gear
selector lever is locked in park
positionP.
If the vehicle’s electrical system
is malfunctioning, the gear
selector lever could remain
locked in park positionP
(
page 400).
íReverse gear
Place gear selector lever in
positionR only when vehicle is
stopped.

Automatic transmission
Effect
ëNeutral
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 engage neutral
positionN while driving.
If the ESP
® is deactivated or
malfunctioning:
Move gear selector lever to neu-
tral positionN only if the vehicle
is in danger of skidding, e.g. on
icy roads.
êDrive
The transmission shifts
automatically. All forward gears
are available.
!Coasting the vehicle, or driving for any other
reason with gear selector lever in neutral
positionN 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 park
positionP is dangerous. Also, park
positionP alone is not intended to or capa-
ble of preventing your vehicle from moving,
possibly hitting people or objects.
Always set the parking brake in addition to
shifting to park positionP (
page 53).
When parked on an incline, turn the 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 or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Children could move the
gear selector lever from park positionP,
which could result in an accident and/or
serious personal injury.

Driving tips
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.
Depending on the engine speed 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 for a longer period of time
with the engine idling and/or on a hill:
Set the parking brake.
Move the gear selector lever to park
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 park positionP. Otherwise the vehicle
could roll away.

Driving systems
Driving systems
The following driving systems are
explained on the following pages:

Cruise control and Distronic*, with
which the vehicle can maintain a preset
speed

Airmatic DC adjusts the vehicle sus-
pension characteristics automatically
and controls the vehicle level

Parktronic system*, which assists the
driver during parking maneuvers
For information on the BAS, ABS, ESP
® and
EBP, see “Driving safety systems”
(
page 89).
Cruise control
The 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 above 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
The cruise control is a convenience system
designed to assist the driver during vehicle
operation. The driver is and must always
remain responsible for the vehicle’s speed
and for safe brake operation.
Only use the cruise control if the road,
traffic, and weather conditions make it ad-
visable 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 the cruise control when driv-
ing 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.

!Moving the gear selector lever to positionN
while driving also cancels the cruise control.
However, 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 the cruise control. After brief acceler-
ation (e.g. for passing), the cruise control will re-
sume the last speed set.
Warning!G
If you increase the vehicle set speed, keep in
mind that it may take a brief moment until
the vehicle has reached the set speed.
Increase the vehicle set speed to a value
that the prevailing road conditions and legal
speed limits permit. Otherwise, sudden and
unexpected acceleration of the vehicle
could cause an accident and/or serious in-
jury to you and others.
