181 Controls in detail
Driving systems
Driving systems
The driving systems of your vehicle are de-
scribed on the following pages:

Cruise control, with which the vehicle
can maintain a preset speed.

Rear Parking Assist*, which assists
your parking maneuvers.
For information on the BAS, ABS, ESP,
4-ETS, and EBB driving systems, see “Driv-
ing and safety systems” (
page 80).
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 23).
i
The cruise control should not be acti-
vated during-off road driving.
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.

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 set
speed is stored for later use.
or
Briefly push the cruise control lever to
position3.
Cruise control is canceled. The last set
speed is stored for later use.
i
On 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
skidding (e.g. on icy roads).
i
The 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.

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.
Cruise control resumes the last set
speed.
Remove your foot from the accelerator
pedal.
i
Depressing the accelerator pedal does
not deactivate cruise control. After
brief acceleration (e.g. for passing),
cruise control will resume the last
speed set.
i
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.

225 Operation
Driving instructions
Tire speed rating
Regardless of the tire speed rating, local
speed limits should be obeyed. Use pru-
dent driving speeds appropriate to prevail-
ing conditions.Your vehicle is factory equipped with
“V”-rated tires, which have a speed rating
of 149 mph (240 km/h).
An electronic speed limiter prevents your
vehicle from exceeding a speed of
130 mph (210 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 cor-
rective steering action.
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 fail-
ure, causing loss of vehicle control and pos-
sibly resulting in an accident and/or serious
injury and possible death, for you and for
others.
i
For information on speed rating for
winter tires, see “Winter driving”
(
page 278).
For additional general information on
tire speed markings on tire sidewall,
see “Tire speed rating” (
page 275).
i
For information on driving with snow
chains, see “Snow chains”
(
page 279).
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.


228 Operation
Driving instructions
Read this chapter carefully before you be-
gin off-road travel.
Familiarize yourself with the vehicle char-
acteristics and gear changing before you
attempt any difficult terrain off-road driv-
ing. We recommend that you start out with
easy off-road travel.Special driving features for off-road
driving
The following driving features are available
for specific kind of operation:

ABS (page 80)

ESP (page 84)

4-ETS (page 83)

Differential lock (page 159)

Transfer case (page 157)
Off-road driving rules
Engage the transfer case in position
LOW before driving under off-road con-
ditions (
page 157).
If necessary activate differential locks
(
page 161).
The ABS, BAS and ESP are switched off
automatically when the differential
locks are activated.
Fasten items being carried as securely
as possible (
page 192).
Never let the vehicle roll backwards in idle.
You may lose control of the vehicle if you
use only the brake.
Sand, dirt, mud and other material having
friction property can cause exceptional wear
and tear as well as brake failure.
Have the brakes checked for dirt build-up
and cleaned. There is otherwise a risk that
full braking power may not be available in an
emergency.i
Whenever driving in off-road mode, we
recommend:

Keeping doors, tailgate, windows
and tilt/sliding sunroof closed.

Switching cruise control off.
!
Observe the following during off-road
driving:

Adjust vehicle speed to condition of
terrain. The more uneven, rutty, and
steeper the terrain, the lower the
speed should be. Drive through wa-
ter slowly at an even speed, avoid-
ing a bow wave.

Be especially careful when driving
in unknown territory. It may be nec-
essary to get out of the vehicle and
scout the path you intend to take.

Watch out for obstacles, such as
rocks, holes, tree stumps, and ruts.
