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
For information on the BAS, ABS and ESP
driving systems, see “Driving safety sys-
tems” (
page 81).
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.
Warning!
G
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 cruise control if the road, the 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.

248 Controls in detailDriving systems1Sets current or higher speed
2 Sets current or lower speed
3 Cancels cruise control
4 Resumes at last set speed
Setting current speed
Accelerate or decelerate to the desired
speed.

Briefly lift 1 or depress 2 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.
Cruise control is canceled. The last
speed set is stored for later use.
or

Briefly push the cruise control lever to
position 3.
Cruise control is canceled. The last
speed set is stored for later use.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.
!Vehicles with automatic transmission:
Moving the gear selector lever to
position N while driving also cancels
cruise control. However, the gear se-
lector lever should not be moved to
position N while driving, except to
coast when the vehicle is in danger of
skidding (e.g. on icy roads).iVehicles with manual transmission:
The set cruise controlled speed is
switched off when declutching exceeds
four seconds during downshifting a
gear.iThe last stored speed is canceled when
you turn off the engine.

Setting a higher speed
Lift cruise control lever to position
1
and hold it up until the desired speed is
reached.

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

Depress cruise control lever to
position 2 and hold it down until the
desired speed is reached.

Release cruise control lever.
The new speed is set. Fine adjustment in 1 mph
(Canada: 1 km/h) increments
Faster

Briefly tip cruise control lever in
direction of arrow
1.
Slower

Briefly tip cruise control lever in
direction of arrow 2. Setting to last stored speed
(“Resume” function)

Briefly push cruise control lever to
position
4.
The cruise control resumes the last 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
automatically downshift 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 preset
speed could cause an accident and/or seri-
ous injury to you and others.

283
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 or,
in case of manual transmission declutch.
Try to keep the vehicle under control by
corrective steering action. Road salts and chemicals can adversely
affect 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
after driving is resumed.
For more information on winter driving, see
“Winter driving” (
page 328).
iFor information on driving with snow
chains, see “Snow chains”
(page 329).
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 loss of control.
Warning!
G
Make sure not to endanger any other road
users when carrying out these braking
maneuvers.
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
resulting in unconsciousness and death.
To assure sufficient fresh air ventilation,
open a window slightly on the side of the
vehicle not facing the wind.Warning!
G
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice.
