SPEED CONTROL
When engaged, the Speed Control takes over accelerator
operations at speeds greater than 25 mph (40 km/h).
The Speed Control buttons are located on the right side of
the steering wheel.NOTE:
In order to ensure proper operation, the Speed
Control System has been designed to shut down if multiple
Speed Control functions are operated at the same time. If
this occurs, the Speed Control System can be reactivated by
pushing the on/off button and resetting the desired vehicle
set speed.
To Activate
Push the on/off button to activate the Speed Control. The
cruise indicator light in the instrument cluster display will
illuminate. To turn the system off, push the on/off button
a second time. The cruise indicator light will turn 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 accidentally set the system or
cause it to go faster than you want. You could lose
control and have an accident. Always leave the system
off when you are not using it.
Speed Control Buttons
1 — On/Off
2 — RES +/Resume/Accel
3 — SET –/Set Speed/Decel
4 — CAN/Cancel 170 STARTING AND OPERATING

Metric Speed (km/h)
•Pushing the SET (-) button once will result in a 1 km/h
decrease in set speed. Each subsequent tap of the button
results in a decrease of 1 km/h.
• If the button is continually pushed, the set speed will
continue to decrease until the button is released, then the
new set speed will be established.
To Accelerate For Passing
Press the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
Using Speed Control On Hills
The transmission may downshift on hills to maintain the
vehicle set speed.
NOTE: The Speed Control system maintains speed up and
down hills. A slight speed change on moderate hills is
normal.
On steep hills, a greater speed loss or gain may occur so it
may be preferable to drive without Speed Control.
WARNING!
Speed Control can be dangerous where the system
cannot maintain a constant speed. Your vehicle could
go too fast for the conditions, and you could lose
control and have an accident. Do not use Speed Control
in heavy traffic or on roads that are winding, icy,
snow-covered or slippery.
To Resume Speed
To resume a previously set speed, push the RES (+) button
and release. Resume can be used at any speed above
20 mph (32 km/h) up to the maximum speed of 100 mph
(160 km/h).
To Deactivate
A soft tap on the brake pedal, pushing the CANC button,
or normal brake pressure while slowing the vehicle will
deactivate the Speed Control without erasing the set speed
from memory.
Pushing the on/off button or turning the ignition switch
OFF erases the set speed from memory.
172 STARTING AND OPERATING

While audible signals are emitted, the audio system is
muted.
The audible signal is turned off immediately if the distance
increases. The tone cycle remains constant if the distance
measured by the inner sensors is constant. If this condition
occurs for the external sensors, the signal is turned off after
three seconds (stopping warnings during maneuvers par-
allel to walls).
ParkSense Rear Park Assist Failure Indications
A malfunction of the ParkSense sensors or system is
indicated, during REVERSE gear engagement, by the in-
strument panel warning icon.The warning icon is illuminated and a message is
displayed on the instrument cluster display (if
equipped). Refer to “Warning Lights And Mes-
sages” in “Getting To Know Your Instrument
Panel” for further information.
The sensors and wiring are tested continuously when the
ignition is in the ON/RUN position. Failures are indicated
immediately if they occur when the system is on.
Even if the system is able to identify that a specific sensor
is in failure condition, the instrument cluster display shall
indicate that the ParkSense system is unavailable, without reference to the sensor in failure condition. If even a single
sensor fails, the entire system must be disabled. The system
is turned off automatically.
Cleaning The ParkSense Rear Park Assist System
Clean the ParkSense sensors with water, car wash soap and
a soft cloth. Do not use rough or hard cloths. In washing
stations, clean sensors quickly while keeping the vapor
jet/high pressure washing nozzles at least 4 inches (10 cm)
from the sensors. Do not scratch or poke the sensors.
Otherwise, you could damage the sensors.
ParkSense Rear Park Assist System Usage
Precautions
NOTE:
•
Ensure that the outer surface and the underside of the
rear bumper is clean and clear of snow, ice, mud, dirt or
other obstruction to keep the ParkSense Rear Park Assist
system operating properly.
• Jackhammers, large trucks, and other vibrations could
affect the performance of the ParkSense system.
• Clean the ParkSense sensors regularly, taking care not to
scratch or damage them. The sensors must not be
covered with ice, snow, slush, mud, dirt or debris.

2. Remove the fuel cap by rotating it counterclockwise.
3. Fully insert the gasoline nozzle into the filler pipe.
4. Fill the vehicle with fuel.
NOTE:When the fuel nozzle “clicks” or shuts off, the fuel
tank is full.
5. Remove gasoline nozzle, reinstall fuel cap and close fuel filler door.WARNING!
•Never have any smoking materials lit in or near the
vehicle when the gas cap is removed or the tank is
being filled.
• Never add fuel when the engine is running. This is
in violation of most state and federal fire regulations
and may cause the MIL to turn on.
• A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on the
ground while filling.
CAUTION!
• Damage to the fuel system or emissions control
system could result from using an improper fuel
tank filler tube cap. A poorly fitting cap could let
impurities into the fuel system and may cause the
“Malfunction Indicator Light (MIL)” to turn on, due
to fuel vapors escaping from the system.
• To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.

Flowing/Rising Water
WARNING!
Do not drive on or across a road or path where water is
flowing and/or rising (as in storm run-off). Flowing
water can wear away the road or path’s surface and
cause your vehicle to sink into deeper water. Further-
more, flowing and/or rising water can carry your ve-
hicle away swiftly. Failure to follow this warning may
result in injuries that are serious or fatal to you, your
passengers, and others around you.
Shallow Standing Water
Although your vehicle is capable of driving through shal-
low standing water, consider the following Cautions and
Warnings before doing so.
WARNING!
•Driving through standing water limits your vehicle’s
traction capabilities. Do not exceed 5 mph (8 km/h)
when driving through standing water.
(Continued)
WARNING! (Continued)
•Driving through standing water limits your vehicle’s
braking capabilities, which increases stopping dis-
tances. Therefore, after driving through standing
water, drive slowly and lightly press on the brake
pedal several times to dry the brakes.
• Failure to follow these warnings may result in inju-
ries that are serious or fatal to you, your passengers,
and others around you.
CAUTION!
• Always check the depth of the standing water before
driving through it. Never drive through standing
water that is deeper than the bottom of the tire rims
mounted on the vehicle.
• Determine the condition of the road or the path that
is under water and if there are any obstacles in the
way before driving through the standing water.
• Do not exceed 5 mph (8 km/h) when driving through
standing water. This will minimize wave effects.
