136 Controls in detailDriving systems
Driving systemsThe 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” sec-
tion (page 66).
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 found on the left-hand side of the
steering column (
page 18).
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 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.

4Resume at last set 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.Canceling cruise control
There are several ways to cancel cruise
control:

Step on the brake pedal.
or

Briefly push the cruise control lever to
position3.
Cruise control will be canceled. The
last speed set will be stored for later
use.Vehicles with manual transmission:
The set cruise controlled speed is switched
off when declutching exceeds four sec-
onds during downshifting a gear. 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.
!Moving gear selector lever to
positionN while driving also cancels
cruise control. However, the gear se-
lector lever should not be moved to
positionN while driving except to coast
when the vehicle is in danger of skid-
ding (e.g. on icy roads).iThe last stored speed is canceled when
you turn off the engine.

138 Controls in detailDriving systemsSetting a higher speed
Lift the cruise control lever to
position1 and hold it up until the de-
sired speed is reached.

Release the cruise control lever.
The new speed is set.
Setting a lower speed

Depress the cruise control lever to
position2 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 (Canada:
1 km/h) increments
Faster

Briefly tip the cruise control lever in the
direction of arrow1.
Slower

Briefly tip the cruise control lever in the
direction of arrow2.Setting to last stored speed
(“Resume” function)

Briefly push the cruise control lever to
position4.
Cruise control will resume the last pre-
viously set speed.

Remove your foot from the accelerator
pedal.
iDepressing the accelerator pedal does
not deactivate cruise control. After
brief acceleration (e.g. for passing),
cruise control will resume the last
speed set.
iVehicles with automatic transmission:
When you use the cruise control lever
to decelerate, the transmission will au-
tomatically downshift if the engine’s
braking power does not brake the vehi-
cle 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 preset
speed could endanger yourself and others.

167 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 positionN or
declutch in case of manual transmission.
Try to keep the vehicle under control by
corrective steering action.Road salts and chemicals can adversely af-
fect braking efficiency. Increased pedal
force may become necessary to produce
the normal brake 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 188).
iFor information on driving with snow
chains, see “Snow chains”
(page 189).
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.

287 Technical terms
ABS
(A
