STOP/START SYSTEM —
DIESEL MODELS ONLY
The Stop/Start function is developed to save
fuel and reduce emissions. 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 on an automatic transmis-
sion or pressing the clutch pedal on a manual
transmission will automatically restart the
engine.

To Start The Engine While In Autostop
Mode
Automatic Transmission:
While in DRIVE, the engine will start when
the brake pedal is released or the throttle
pedal is depressed. The transmission will
automatically re-engage upon engine restart.
During this transition, the brakes will hold
the vehicle to avoid undesired vehicle move-
ment.
Manual Transmission:
When the gear selector is in NEUTRAL, the
engine will start when the clutch pedal is
pressed. The vehicle will go into STOP/
START SYSTEM NOT READY mode until the
vehicle speed is greater than 4 mph (7 km/h).
Conditions That Will Cause The Engine To Start
Automatically While In Autostop Mode:
• The transmission gear selector is movedfrom DRIVE to REVERSE or NEUTRAL.
• To maintain cabin temperature comfort.
• HVAC is set to full defrost mode. • Battery voltage drops too low.
• Low brake vacuum (e.g. after several brake
pedal applications).
• STOP/START OFF switch is pushed.
• 4WD system is put into 4LO mode.
• The emissions system requires it.
• A STOP/START system error occurs.
• HVAC system temperature or fan speed is manually adjusted.
Conditions That Force An Application Of The
Electric Park Brake While In Autostop Mode:
• The driver door is open and brake pedal released.
• The driver door is open and the driver seat belt is unbuckled.
• The engine hood has been opened.
• A STOP/START system error occurs.
If the Electric Park Brake is applied with the
engine off, the engine may require a manual
restart and the electric park brake may re-
quire a manual release (depress brake pedal
and push Electric Park Brake switch). Refer to “Instrument Cluster Display” in “Getting
To Know Your Instrument Panel” in your Own-
er’s Manual for further information.

SPEED CONTROL
The Speed Control switches are located on
the right side of the steering wheel.
Activation
Push the on/off button to activate the Speed
Control, “CRUISE CONTROL READY” will
appear on the instrument cluster display to indicate the Speed Control is on. Push the
on/off button a second time to turn the sys-
tem off, “CRUISE CONTROL OFF” will ap-
pear on the instrument cluster display to
indicate the Speed Control is off. The system
should be turned off when not in use.
WARNING!
Leaving the Speed Control system on when
not in use is dangerous. You could acci-
dentally set the system or cause it to go
faster than you want. You could lose con-
trol and have an accident. Always leave the
system off when you are not using it.
Setting A Desired Speed
Turn the Speed Control on. When the vehicle
has reached the desired speed, push the SET
(+) or SET (-) button and release. Release the
accelerator and the vehicle will operate at the
selected speed. Once a speed has been set, a
message “CRUISE CONTROL SET TO MPH
(km/h)” will appear indicating what speed

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.

WARNING!
• Never add fuel when the engine is run-ning. This is in violation of most coun-
tries regulations and may cause the
“Malfunction Indicator Light” to turn
on.
• A fire may result if fuel is pumped into a
portable container that is inside of a
vehicle. You could be burned. Always
place fuel containers on the ground
while filling.
CAUTION!
• Damage to the fuel system or emissioncontrol system could result from using
an improper fuel filler cap. A poorly
fitting cap could let impurities into the
fuel system. Also, a poorly fitting after-
market cap can cause the “Malfunction
Indicator Light (MIL)” to illuminate, due
to fuel vapors escaping from the system.
• A poorly fitting fuel filler cap may cause
the MIL to turn on.
CAUTION!
• To avoid fuel spillage and overfilling, donot “top off” the fuel tank after filling.
• If fuel is spilled on surface on the paint,
clear it immediately to avoid damage the
paint.
