5-20 Instruments and Controls
the battery has recently been
replaced or if the battery has run
down. The diagnostic system is
designed to evaluate critical
emission control systems during
normal driving. This can take
several days of routine driving.
If this has been done and the
vehicle still does not pass the
inspection for lack of OBD II
system readiness, your dealer/
retailer can prepare the vehicle
for inspection.
Brake System Warning
Light
This vehicle's hydraulic brake
system is divided into two parts.
If one part is not working, the other
part can still work and stop the
vehicle. For good braking both parts
need to be working.
If the warning light comes on, there
is a brake problem. Have the brake
system inspected right away.
United StatesCanada
This light should come on briefly
when the ignition key is turned to
ON/RUN. If it does not come on
then, have it fixed so it will be ready
to warn if there is a problem.
This light may also come on due to
low brake fluid. See Brakes
on
page 10‑22for more information.
When the ignition is on, the brake
system warning light will also come
on when the parking brake is set.
The light will stay on if the parking
brake does not release fully. If it
stays on after the parking brake is
fully released, it means there is a
brake problem. If the light comes on while driving,
pull off the road and stop carefully.
Make sure the parking brake is fully
released. The pedal may be harder
to push or, the pedal may go closer
to the floor. It may take longer to
stop. If the light is still on, have the
vehicle towed for service. See
Towing the Vehicle on page 10‑83.
{WARNING
The brake system might not be
working properly if the brake
system warning light is on.
Driving with the brake system
warning light on can lead to a
crash. If the light is still on after
the vehicle has been pulled off
the road and carefully stopped,
have the vehicle towed for
service.

SERVICE TIRE MONITOR
SYSTEM
On vehicles with the Tire Pressure
Monitor System (TPMS), this
message displays if a part on the
TPMS is not working properly. The
tire pressure light also flashes and
then remains on during the same
ignition cycle. See Tire Pressure
Light
on page 5‑22. Several
conditions may cause this message
to appear. See Tire Pressure
Monitor Operation
on page 10‑46for
more information. If the warning
comes on and stays on, there may
be a problem with the TPMS. See
your dealer/retailer.
TIRE LEARNING ACTIVE
This message displays when the
Tire Pressure Monitor System
(TPMS) is re-learning the tire
positions on your vehicle. The tire
positions must be re-learned after
rotating the tires or after replacing a
tire or sensor. See Tire Rotation
on
page 10‑49, Tire Pressure Monitor
Systemon page 10‑44, and Tire
Pressureon page 10‑43for more
information.
Transmission Messages
ALL WHEEL DRIVE OFF
If your vehicle has the All-Wheel
Drive (AWD) system, this message
displays when there is a compact
spare tire on the vehicle, when the
Antilock Brake System (ABS)
warning light comes on, or when the
rear differential fluid is overheating.
This message turns off when the
differential fluid cools. The AWD system is disabled until
the compact spare tire is replaced
by a full-size tire. If the warning
message is still on after putting on
the full-size tire, you need to reset
the warning message. To reset the
warning message, turn the ignition
off and then back on again after
30 seconds. If the message stays
on, see your dealer/retailer right
away. See
All-Wheel Drive
on
page 9‑25for more information.
SERVICE ALL WHEEL DRIVE
If your vehicle has the All-Wheel
Drive (AWD) system, this message
displays if there is a problem with
this system. If this message
appears, stop as soon as possible
and turn off the vehicle. Restart the
vehicle after 30 seconds and check
for the message on the DIC display.
If the message is still displayed or
appears again when you begin
driving, the AWD system needs
service. See your dealer/retailer.

Hydroplaning
Hydroplaning is dangerous. Water
can build up under your vehicle's
tires so they actually ride on the
water. This can happen if the road is
wet enough and you are going fast
enough. When your vehicle is
hydroplaning, it has little or no
contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is to
slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping
equipment in good shape.
.Keep the windshield washer fluid
reservoir filled.
.Have good tires with proper
tread depth. SeeTireson
page 10‑37.
.Turn off cruise control.
Highway Hypnosis
Always be alert and pay attention to
your surroundings while driving.
If you become tired or sleepy, find a
safe place to park your vehicle
and rest.
Other driving tips include:
.Keep the vehicle well ventilated.
.Keep interior temperature cool.
.Keep your eyes moving —scan
the road ahead and to the sides.
.Check the rearview mirror and
vehicle instruments often.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. Tips for
driving in these conditions include:
.Keep the vehicle serviced and in
good shape.
.Check all fluid levels and brakes,
tires, cooling system, and
transmission.
.Going down steep or long hills,
shift to a lower gear.
{WARNING
If you do not shift down, the
brakes could get so hot that they
would not work well. You would
then have poor braking or even
none going down a hill. You could
crash. Shift down to let the engine
assist the brakes on a steep
downhill slope.

9-30 Driving and Operating
Cruise Control
With cruise control, a speed of
about 40 km/h (25 mph) or more can
be maintained without keeping your
foot on the accelerator. Cruise
control does not work at speeds
below about 40 km/h (25 mph).
When the brakes are applied, the
cruise control is disengaged.
{WARNING
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. So, do not use
the cruise control on winding
roads or in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
The cruise control buttons are
located on left side of the steering
wheel.
T(On/Off):Press to turn cruise
control on and off. The indicator
comes on when cruise control is on.
+ RES (Resume/Accelerate):
Press to make the vehicle
accelerate or resume to a previously
set speed.
SET– :Press to set the speed or
make the vehicle decelerate.
[(Cancel): Press to cancel cruise
control. Setting Cruise Control
Cruise control will not work if the
parking brake is set, or if the master
cylinder brake fluid level is low.
The cruise control light on the
instrument panel cluster comes on
after the cruise control has been set
to the desired speed.
{WARNING
If you leave your cruise control on
when you are not using cruise,
you might hit a button and go into
cruise when you do not want to.
You could be startled and even
lose control. Keep the cruise
control switch off until you want to
use cruise control.
1. Press the
Ibutton.
2. Get up to the speed desired.

3. Drive slowly until the trailer isclear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer
Towing
The vehicle needs service more
often when pulling a trailer. See this
manual's Maintenance Schedule or
Index for more information. Things
that are especially important in
trailer operation are automatic
transmission fluid, engine oil, axle
lubricant, belts, cooling system and
brake system. Inspect these before
and during the trip.
Check periodically to see that all
hitch nuts and bolts are tight.
Engine Cooling When Trailer
Towing
The cooling system may temporarily
overheat during severe operating
conditions. See Engine Overheating
on page 10‑18.
Trailer Towing
Three important considerations
have to do with weight:
.The weight of the trailer
.The weight of the trailer tongue
.The total weight on the vehicle's
tires
Weight of the Trailer
How heavy can a trailer safely be?
Speed, altitude, road grades,
outside temperature, special
equipment, and the amount of
tongue weight the vehicle can carry
must be considered. See “Weight of
the Trailer Tongue” later in this
section for more information.
Maximum trailer weight is calculated
assuming only the driver is in the
tow vehicle and it has all the
required trailering equipment.
The weight of additional optional
equipment, passengers and cargo in
the tow vehicle must be subtracted
from the maximum trailer weight.
