depends on

the coolant temperature

the battery voltage
Regardless of the temperature and air volume
set on the climate control panel, an interior
temperature is aimed at by 72°F (22°C) and the
blower runs on low speed to protect the vehicle
battery.
iThe residual heat is automatically turned off:

when the ignition is switched on

after about 30 minutes

if the coolant temperature is too low

if the battery voltage drops

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

Cruise control (page 197), with
which the vehicle can maintain a preset
speed.

Rear Parking Assist (page 200) and
rear view camera (
page 203), which
serve as parking aid.
For information on the ABS, BAS, ESP
®,
4-ETS, and EBB driving systems, see “Driv-
ing safety systems” (
page 88).
Cruise control
The cruise control automatically maintains
the speed you set for your vehicle.
The use of the cruise control is recom-
mended for driving at a constant speed for
extended periods of time. You can set or
resume the 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 24).
iThe cruise control should not be activated
during-off road driving.
Warning!G
The cruise control is a convenience 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 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 the cruise control can be
dangerous on winding roads or in heavy
traffic because conditions do not allow
safe driving at a steady speed.

The use of the cruise control can be
dangerous on slippery roads. Rapid
changes in tire traction can result in
wheel spin and loss of control.

Deactivate the cruise control when
driving in fog.
The “Resume” function should only be
operated if the driver is fully aware of the
previously set speed and wishes to resume
this particular preset speed.

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.
!Moving the gear selector lever to neutral
positionN while driving also cancels the cruise
control. However, the gear selector lever should
not be moved to neutral 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.
Warning!G
If you increase the vehicle set speed, keep in
mind that it may take a brief moment until
the vehicle has reached the set speed.
Increase the vehicle set speed to a value
that the prevailing road conditions and legal
speed limits permit. Otherwise, sudden and
unexpected acceleration of the vehicle
could cause an accident and/or serious in-
jury to you and others.

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 the
preset speed could cause an accident
and/or serious injury to you and others.
