tain operating conditions), the transmis-
sion may use second gear (rather than first
gear) during launches, to minimize wheel
slippage.
• Sport — This mode alters the transmis-
sion's automatic shift schedule for sportier
driving. Upshift speeds are increased to
make full use of available engine power.
NOTE:
SPORT mode is not available when 4WD LOW
is selected.
• Sand/Mud — Off-road calibration for use on
low traction surfaces such as mud, sand, or
wet grass. Driveline is maximized for trac-
tion. Some binding may be felt on less
forgiving surfaces. The electronic brake

equipped with the Off-Road package.
• Activate the Hill Descent Control or Selec Speed Control for steep downhill control.
See “Electronic Brake Control System” in
“Safety” for further information.
STOP/START SYSTEM —
IF EQUIPPED
The Stop/Start function was developed to
reduce fuel consumption. The system will
stop the engine automatically during a ve-
hicle stop if the required conditions are met.
Releasing the brake pedal or pressing the
accelerator pedal will automatically restart
the engine.
This vehicle has been upgraded with a Heavy
Duty Battery, Starter, as well as other engine
parts, to handle the Additional engine starts.
Automatic Mode
The Stop/Start feature is enabled after every
normal customer engine start. At that time,
the system will go into STOP/START READY
and if all other conditions are met, can go
into a STOP/START AUTOSTOP ACTIVE “Au-
tostop” mode.
To Activate The Autostop Mode, The Following
Must Occur:
• The system must be in STOP/STARTREADY state. A STOP/START READY mes-
sage will be displayed in the instrument
cluster display within the Stop/Start sec-
tion. Refer to “Warning Lights And Mes-
sages” in “Getting To Know Your Instru-
ment Panel” in your Owner’s Manual.
• The vehicle must be completely stopped.
• The gear selector must be in a forward gear and the brake pedal depressed.
The engine will shut down, the tachometer
will move to the zero position and the Stop/
Start telltale will illuminate indicating you
are in Autostop. Customer settings will be
maintained upon return to an engine running
condition.
STARTING AND OPERATING
136

Remove your foot from the accelerator pedal.
If you do not, the vehicle may continue to
accelerate beyond the set speed. If this oc-
curs:
• The message “DRIVER OVERRIDE” willappear in the instrument cluster display.
• The system will not be controlling the dis- tance between your vehicle and the vehicle
ahead. The vehicle speed will only be de-
termined by the position of the accelerator
pedal.
Varying The Speed
Once the ACC has been activated, the speed
can be increased or decreased.
NOTE:
• When you override and push the SET (+)
button or SET (-)buttons, the new set
speed will be the current speed of the
vehicle.
• When you use the SET (-)button to decel-
erate, if the engine’s braking power does
not slow the vehicle sufficiently to reach
the set speed, the brake system will auto-
matically slow the vehicle. • The ACC system applies the brake down to
a full stop when following a target vehicle.
If an ACC host vehicle follows a target
vehicle to a standstill, the host vehicle will
release the vehicle brakes two seconds af-
ter coming to a full stop.
• The ACC system maintains set speed when driving up hill and down hill. However, a
slight speed change on moderate hills is
normal. In addition, downshifting may oc-
cur while climbing uphill or descending
downhill. This is normal operation and nec-
essary to maintain set speed. When driving
up hill and down hill, the ACC system will
cancel if the braking temperature exceeds
normal range (overheated).
To Increase Speed
While ACC is set, you can increase the set
speed by pushing the SET (+)button.
The driver's preferred units can be selected
through the instrument panel settings if
equipped. Refer to “Getting To Know Your
Instrument Panel” in the Owner’s Manual for
further information. The speed increment
shown is dependant on the chosen speed unit
of U.S. (mph) or Metric (km/h): U.S. Speed (mph)
• Pushing the SET
(+)button once will result
in a 1 mph increase in set speed. Each
subsequent tap of the button results in an
increase of 1 mph.
• If the button is continually pushed, the set speed will continue to increase in 5 mph
increments until the button is released.
The increase in set speed is reflected in the
instrument cluster display.
Metric Speed (km/h)
• Pushing the SET (+)button once will result
in a 1 km/h increase in set speed. Each
subsequent tap of the button results in an
increase of 1 km/h.
• If the button is continually pushed, the set speed will continue to increase in 10 km/h
increments until the button is released.
The increase in set speed is reflected in the
instrument cluster display.
To Decrease Speed
While ACC is set, the set speed can be de-
creased by pushing the SET (-)button.

• To increase the distance setting, push theDistance Setting—Increase button and re-
lease. Each time the button is pushed, the
distance setting increases by one bar (lon-
ger).
• To decrease the distance setting, push the Distance Setting—Decrease button and re-
lease. Each time the button is pushed, the
distance setting decreases by one bar
(shorter).
Changing Modes
If desired, the Adaptive Cruise Control mode
can be turned off and the system can be
operated as a Normal (Fixed Speed) Cruise
Control mode. When in the Normal (Fixed
Speed) Cruise Control mode the distance
setting feature will be disabled and the sys-
tem will maintain the speed you set.
• To change between the different cruisecontrol modes, push the Adaptive Cruise
Control (ACC) on/off button which turns the
ACC and the Normal (Fixed Speed) Cruise
Control off. • Pushing the Normal (Fixed Speed) Cruise
Control on/off button will result in turning
on (changing to) the Normal (Fixed Speed)
Cruise Control mode.
Refer to “Normal (Fixed Speed) Cruise Con-
trol Mode” in “Starting And Operating” in
your Owner's Manual for further information.
WARNING!
Adaptive Cruise Control (ACC) is a conve-
nience system. It is not a substitute for
active driving involvement. It is always the
driver’s responsibility to be attentive of
road, traffic, and weather conditions, ve-
hicle speed, distance to the vehicle ahead;
and, most importantly, brake operation to
ensure safe operation of the vehicle under
all road conditions. Your complete atten-
tion is always required while driving to
maintain safe control of your vehicle. Fail-
ure to follow these warnings can result in a
collision and death or serious personal
injury.
The ACC system:
• Does not react to pedestrians, oncoming vehicles, and stationary objects (e.g., a
WARNING!
stopped vehicle in a traffic jam or a
disabled vehicle).
• Cannot take street, traffic, and weather
conditions into account, and may be
limited upon adverse sight distance con-
ditions.
• Does not always fully recognize complex
driving conditions, which can result in
wrong or missing distance warnings.
• Will bring the vehicle to a complete stop
while following a target vehicle and hold
the vehicle for 2 seconds in the stop
position. If the target vehicle does not
start moving within two seconds the ACC
system will display a message that the
system will release the brakes and that
the brakes must be applied manually. An
audible chime will sound when the
brakes are released.
You should switch off the ACC system:
• When driving in fog, heavy rain, heavy
snow, sleet, heavy traffic, and complex
driving situations (i.e., in highway con-
struction zones).
STARTING AND OPERATING

WARNING!
• When entering a turn lane or highway offramp; when driving on roads that are
winding, icy, snow-covered, slippery, or
have steep uphill or downhill slopes.
• When towing a trailer up or down steep
slopes.
• When circumstances do not allow safe
driving at a constant speed.
The Cruise Control system has two control
modes:
•
Adaptive Cruise Control mode for main-
taining an appropriate distance between
vehicles.
• Normal (Fixed Speed) Cruise Control
mode for cruising at a constant preset
speed. For additional information, refer
to “Normal (Fixed Speed) Cruise Control
Mode” in your Owner’s Manual for fur-
ther information.
Normal (Fixed Speed) Cruise Control will not
react to preceding vehicles. Always be aware
of the mode selected. You can change the
mode by using the Cruise Control buttons.
The two control modes function differently.
Always confirm which mode is selected.
PARKSENSE REAR PARK

Jack Usage Precautions
To complete the Use and Maintenance Hand-
book to which this supplement is attached,
given below are some instructions on the
proper use of the jack.
WARNING!
When using the crank, make sure it turns
freely without the risk of scraping hands
against the ground.
Even the moving parts of the jack, the
“worm screw” and joints can cause inju-
ries: avoid contact with them. Clean it
thoroughly if dirtied with grease.
CAUTION!
The jack is a tool designed exclusively for
changing a wheel, in case of a puncture or
damage to a tire of the vehicle on which it
is fitted or on vehicles of the same model.
Any other use, e.g. to jack up other vehicle
models or different things, is strictly pro-
hibited. Never use it to carry out mainte-
nance or repairs under the vehicle or to
CAUTION!
change summer/winter wheels and vice
versa. Never go under the raised vehicle. If
any work under the vehicle is necessary,
contact an authorized dealer. Incorrect
placing of the jack can cause the vehicle to
drop: use it only in the positions indicated.
Do not use the jack for loads higher than
that specified on the label. Never start the
engine with vehicle raised. If the vehicle is
raised more than necessary, everything
can become more unstable, with the risk
of the vehicle dropping violently. Therefore
raise the vehicle only as much as neces-
sary for the wheel/spare.
Maintenance
• Make sure grime does not build up on the “worm screw.”
• Keep the “worm screw” lubricated.
• Never modify the jack.
Conditions Of Non-Use:
• Temperatures below −40°C.
• On sandy or muddy ground.
• On uneven ground. • On steep roads.
• In extreme weather conditions: thunder-
storms, typhoons, hurricanes, blizzards,
storms, etc.
TIRE SERVICE KIT —
IF EQUIPPED
