Driving systems
Driving systems
The driving system of your vehicle is
described on the following pages:

Cruise control, with which the vehicle
can maintain a preset speed.
The BAS, ABS and ESP
® driving systems
are described in the “Safety and Security”
section (
page 84).
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 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
The cruise control is a convenience system
designed to assist the driver during vehicle
operation. The driver is and must remain at
all times responsible for the vehicle speed
and for safe brake operation.
Only use the 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 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.

Warning!G
Cruise control brakes automatically so that

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
vehicle’s speed and for safe braking
operation.
Keep driver’s foot area clear at all times,
including the area under the brake pedal.
Objects 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.

iOn uphill or downhill grades, the 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 maintains
the set speed with braking from the vehicle’s
braking system.
In addition, on longer downhill grades the
automatic transmission* will automatically
downshift.
iVehicles with manual transmission:
If you depress the clutch pedal when shifting into
another gear, the engine speed may increase.

Drive with sufficient engine speed.

Shift gears in a timely manner.

If possible, do not shift down more than one
gear.

Vehicles with manual transmission:
you depress the clutch pedal for longer than
6 seconds during shifting into another gear.

Vehicles with automatic transmission*:
you move the gear selector lever to
positionN while driving.
!Vehicles with automatic transmission*:
Moving gear selector lever to positionN while
driving also cancels 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
acceleration (e.g. for passing), the cruise
control will resume the last speed set.
