MIST:Turn the band to MIST for a single wiping cycle.
Hold it until the windshield wipers start. Then let it
go. The windshield wipers will stop after one wipe.
If more wipes are needed, hold the band on
MIST longer.
Be sure to clear ice and snow from the windshield wiper
blades before using them. If they are frozen to the
windshield, carefully loosen or thaw them. If the blades
do become worn or damaged, get new blades or
blade inserts. SeeWindshield Wiper Blade Replacement
on page 5-52.
Heavy snow or ice can overload the wipers. A circuit
breaker will stop them until the motor cools. Clear away
snow or ice to prevent an overload.Windshield Washer
J(Windshield Washer):A paddle with the word
PUSH on it is located at the top of the multifunction
lever. Push on the paddle to spray washer uid on the
windshield. The wipers will run for several sweeps
and then either stop or return to the preset speed.
SeeWindshield Washer Fluid on page 5-35.
{CAUTION:
In freezing weather, do not use your washer
until the windshield is warmed. Otherwise the
washer uid can form ice on the windshield,
blocking your vision.
The LOW WASH light on
the instrument panel
cluster will come on when
the uid level is low.

1. Move the cruise control switch to ON.
2. Accelerate to the desired speed.
3. Push in the SET button at the end of the
multifunction lever and release it. The CRUISE light
on the instrument panel cluster will come on.
4. Take your foot off the accelerator pedal.
Resuming a Set Speed
If the cruise control is set at a desired speed and
the brakes are applied, the cruise control turns off.
But it does not need to be reset.
Once the vehicle is going about 25 mph (40 km/h) or
more, move the cruise control switch from ON to
R/A (Resume/Accelerate) briey. The vehicle will
accelerate to the previous chosen speed and stay there.
Increasing Speed While Using
Cruise Control
There are two ways to go to a higher speed:
Use the accelerator pedal to get to the higher
speed. Push in the SET button, then release
the button and the accelerator pedal. The vehicle
will now cruise at the higher speed.
Move the cruise switch from ON to R/A. Hold it
there until the vehicle accelerates to the desired
speed, then release the switch. To increase
the speed in very small amounts, move the switch
to R/A briey and then release it. Each time
this is done, the vehicle will go about 1 mph
(1.6 km/h) faster.
The accelerate feature will only work after the cruise
control speed is set, by pushing the SET button.

Speedometer and Odometer
The speedometer shows the vehicle’s speed in both
miles per hour (mph) and kilometers per hour (km/h).
The odometer shows how far the vehicle has been
driven in either miles (used in the United States) or in
kilometers (used in Canada).
The vehicle has a tamper-resistant odometer. If ERROR
is displayed, this indicates someone has probably
tampered with it and the numbers may not be accurate.
You may wonder what happens if the vehicle needs
a new odometer installed. If the new one can be set to
the mileage total of the old odometer, then that will
be done. But if it cannot, then it will be set at zero and a
label must be put on the driver’s door to show the old
mileage reading when the new odometer was installed.
Trip Odometer
The trip odometer tells how far the vehicle has been
driven since it was last reset. To set the trip odometer to
zero, press the button on the right side of the instrument
panel cluster.
The trip/select reset button will go back and forth
between the odometer and the trip odometer if the
button is pressed and released within 1.5 seconds.If the button is pressed and held for longer than
1.5 seconds while in the trip odometer mode, it will be
reset to zero. If the button is pressed and held for longer
than 1.5 seconds while in the odometer mode, it will
have no effect.
Safety Belt Reminder Light
When the ignition key is turned to RUN or START,
a chime will come on for several seconds to remind
occupants to fasten their safety belts.
The safety belt light will
also come on and stay on
for several seconds, then it
will ash for several more.
If the driver’s belt is already buckled, neither the chime
nor the light will come on.
3-30

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 the vehicle is being driven,
pull off the road and stop carefully. The pedal may
be harder to push, or it may go closer to the oor. It may
take longer to stop. If the light is still on, have the
vehicle towed for service. SeeTowing Your Vehicle on
page 4-36.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light is
on. Driving with the brake system warning light
on can lead to an accident. If the light is still
on after you have pulled off the road and
stopped carefully, have the vehicle towed
for service.
Anti-Lock Brake System
Warning Light
If the vehicle has anti-lock brakes, this warning light will
come on for a few seconds when the ignition key is
turned to RUN. If the anti-lock brake system warning light
stays on longer than normal after the engine has been
started, turn the ignition off. Or, if the light comes on and
stays on while the vehicle is being driven, stop as soon as
possible and turn the ignition off. Then start the engine
again to reset the system. If the light still stays on, or
comes on again while driving, the anti-lock brake system
needs service. If the light is on and the regular brake
system warning light is not on, the vehicle still has brakes,
but it does not have anti-lock brakes.
The anti-lock brake system warning light will come on
briey when the ignition key is turned to RUN. This is
normal. If the light does not come on then, have it xed
so it will be ready to warn you if there is a problem.United States

Tire Pressure Light
The vehicle may have a
tire pressure monitor that
indicates a large change
in the pressure in one tire.
The system stores the tire pressures of the vehicle’s
properly inated tires. The LOW TIRE light will come on
if the pressure in one tire becomes 12 psi (83 kPa)
lower than the other three tires. The LOW TIRE light will
not come on if the pressure in more than one tire is
low, if the system is not yet calibrated, or if the vehicle
is moving faster than 70 mph (110 km/h).
When the LOW TIRE light comes on, stop as soon as
possible and check all the tires for damage. If a tire
is at, seeIf a Tire Goes Flat on page 5-69. Also check
the tire pressure in all four tires as soon as possible.
SeeInation - Tire Pressure on page 5-60.
The light will stay on, while the ignition is on, until the
system is reset. SeeTire Pressure Monitor System
on page 5-61.
Malfunction Indicator Lamp
Service Engine Soon Light
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition, and emission
control systems.
This system is called OBD II (On-Board Diagnostics
Second Generation) and is intended to assure that
emissions are at acceptable levels for the life of
the vehicle, helping to produce a cleaner environment.
The SERVICE ENGINE SOON light comes on and
a chime will sound to indicate that there is a problem
and service is required. Malfunctions often will be
indicated by the system before any problem is apparent.
This may prevent more serious damage to your
vehicle. This system is also designed to assist
your service technician in correctly diagnosing
any malfunction.

Security Light
The SECURITY light will
come on when the key is
turned to START, and
will stay on until the
vehicle starts.
It will also ash if the ignition key is too dirty or wet for
the PASS-Key
®II system to read the resistor pellet.
SeePASS-Key®II on page 2-16.
If the resistor pellet is damaged or missing, the light
will come on.
Cruise Control Light
The CRUISE light comes
on whenever the cruise
control is set. See “Cruise
Control” underTurn
Signal/Multifunction Lever
on page 3-7.
Low Washer Fluid Warning Light
If the LOW WASH light
comes on when the
windshield washer paddle
is used, this indicates
that the uid is low
in the windshield
washer reservoir.
The light will also come on briey when the ignition is
turned on to show that it is working properly.
