197 Controls in detail
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, (
page 79).
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 30).
Warning!
G
Cruise control is a convenience system de-
signed to assist the driver during vehicle op-
eration. 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, 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.

198 Controls in detailDriving systems1Sets current or higher speed
2Sets current or lower speed
3Cancels cruise control
4Resumes 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.
Cruise control is canceled. The last
speed set is stored for later use.
or

Briefly push the cruise control lever to
position3.
Cruise control is canceled. The last
speed set is stored for later use.The cruise control is automatically can-
celled, when


ESP works to stabilize the vehicle


you move the gear selector lever to
positionN
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.
!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).iThe last stored speed is canceled when
you turn off the engine.

Setting a higher speed
Lift cruise control lever to position1
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
position2 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 arrow1.
Slower

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

Briefly push cruise control lever to
position4.
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.
iWhen 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.

235 Operation
Driving instructions
Your vehicle is factory equipped with
“(Y)”-rated tires, which have a speed rating
of over 186 mph (300 km/h).
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.
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
efficiency should be tested as soon as
possible after driving is resumed.
Warning!
G
Even when permitted by law, never operate
a vehicle at speeds greater than the maxi-
mum speed rating of the tires.
Exceeding the maximum speed for which
tires are rated can lead to sudden tire
failure, causing loss of vehicle control and
possibly resulting in an accident and/or
personal injury and possible death, for you
and for others.iFor information on tire speed rating for
winter tires, see “Winter tires*”
(page 284).
For additional general information on
tire speed markings on tire sidewall,
see “Tire speed rating” (
page 271).
iFor information on driving with snow
chains, see “Snow chains”
(page 285).
Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced
vehicle control. Your vehicle’s ABS will not
prevent this type of control loss.
Warning!
G
Make sure not to endanger any other road
users when carrying out these braking
maneuvers.
