WARNING LIGHTS AND CHIMES
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause expensive repairs. A warning light may
illuminate when a problem exists with one of your vehicle’s functions.
Many lights will illuminate when you start your vehicle to make sure the
bulb works.If any light remains on after starting the vehicle, have
the respective system inspected immediately.
Service engine soon
Your vehicle is equipped with a
computer that monitors the engine’s
emission control system. This
system is commonly known as the
On Board Diagnostics System
(OBD). This OBD system protects
the environment by ensuring that your vehicle continues to meet
government emission standards. The OBD system also assists the service
technician in properly servicing your vehicle.
TheService Engine Soonindicator light illuminates when the ignition is
first turned to the ON position to check the bulb. If it comes on after the
engine is started, one of the engine’s emission control systems may be
malfunctioning. The light may illuminate without a driveability concern
being noted. The vehicle will usually be drivable and will not require
towing.

5. Turn the key to 4 (ON) without
turning the key to 5 (START).
If there is difficulty in turning the
key, firmly rotate the steering wheel
left and right until the key turns
freely. This condition may occur
when:
•front wheels are turned
•front wheel is against the curb
•steering wheel is turned when getting in or out of the vehicle
Make sure the corresponding lights illuminate or illuminate briefly. If a
light fails to illuminate, have the vehicle serviced.
•If the driver’s safety belt is fastened, the
light may not illuminate.
Starting the engine
Note:Whenever you start your vehicle, release the key as soon as the
engine starts. Excessive cranking could damage the starter.
1. Turn the key to 5 (START)
without pressing the accelerator
pedal and release as soon as the
engine starts. The key will return to
4 (ON).
2. If the temperature is above –12°
C (10° F) and the engine does not
start within five seconds on the first
try, turn the key to OFF, wait 10
seconds and try again.

3. If the temperature is below -12° C (10° F) and the engine does not
start in 15 seconds on the first try, turn the key OFF and wait 10
seconds and try again. If the engine does not start in two attempts, press
the accelerator pedal all the way to floor and hold. Turn the key to
START position.
4. When the engine starts, release the key, then release the accelerator
pedal gradually as the engine speeds up.
5. After idling for a few seconds, apply the brake and release the parking
brake.
Using the engine block heater (if equipped)
An engine block heater warms the engine coolant, which improves
starting, warms up the engine faster and allows the heater-defroster
system to respond quickly. Use of an engine block heater is strongly
recommended if you live in a region where temperatures reach -23° C
(-10° F) or below.
For best results, plug the heater in at least three hours before starting
the vehicle. Using the heater for longer than three hours will not harm
the engine, so the heater can be plugged in the night before starting the
vehicle.
To prevent electrical shock, do not use your heater with
ungrounded electrical systems or two-pronged (cheater)
adapters.
Guarding against exhaust fumes
Although odorless and colorless, carbon monoxide is present in exhaust
fumes. Take precautions to avoid its dangerous effects.
If you ever smell exhaust fumes of any kind inside your vehicle,
have your dealer inspect and fix your vehicle immediately. Do
not drive if you smell exhaust fumes. These fumes are harmful and
could kill you.
Have the exhaust and body ventilation systems checked whenever:
•the vehicle is raised for service
•the sound of the exhaust system changes
•the vehicle has been damaged in a collision

Hydraulic brake booster system (Hydroboost or Hydromax)
The Hydroboost and Hydromax systems receive fluid pressure from the
power steering pump to provide power assist during braking.
The Hydromax booster receives backup pressure from the reserve
system electric pump whenever the fluid in the power steering system is
not flowing. When the engine is OFF, the pump will turn on if the brake
pedal is applied, or if the ignition is turned to the ON position.
The sound of the pump operating may be heard by the driver, but this is
a normal characteristic of the system.
The reserve system provides reduced braking power, so the vehicle
should be operated under these conditions with caution, and only to seek
service repair and remove the vehicle from the roadway.
For Hydromax-equipped vehicles operating under normal conditions, the
noise of the fluid flowing through the booster may be heard whenever
the brake is applied. This condition is normal. Vehicle service is not
required.
If braking performance or pedal response becomes very poor, even when
the pedal is strongly depressed, it may indicate the presence of air in the
hydraulic system or leakage of fluid. Stop the vehicle safely as soon as
possible and seek service immediately.
ABS warning lamp
ABS
TheABSwarning lamp in the instrument cluster momentarily illuminates
when the ignition is turned to the ON position. If the light remains on
after the vehicle is started, continues to flash or fails to illuminate, have
the system serviced immediately. With the ABS light on, the anti-lock
brake system is disabled and normal braking is still effective unless the
brake warning light also remains illuminated.
With the ABS light on, the anti-lock
brake system is disabled and normal
braking is still effective unless the
brake warning light also remains
illuminated with parking brake
released. (If your brake warning lamp illuminates, have your vehicle
serviced immediately.)

Each time the vehicle is started, the transmission will automatically
return to normal overdrive mode.
Every time the vehicle is shut off and restarted, you must press the
transmission control switch to cancel overdrive operation if driving in
overdrive is not desired.
2 (Second)
Use 2 (Second) to start-up on
slippery roads or to provide
additional engine braking on
downgrades.
1 (First)
Use 1 (Low) to provide maximum
engine braking on steep
downgrades. Upshifts can be made
by shifting to 2 (Second) or to
(Overdrive). Selecting 1 (Low) at
higher speeds causes the transmission to shift to a lower gear, and will
shift to 1 (Low) after vehicle decelerates to the proper speed.
Forced Downshifts
To gain acceleration in
(Overdrive) or Drive (O/D OFF) when
passing another vehicle, push the accelerator to the floor. The
transmission will downshift to the appropriate gear: third, second or first
gear.
DRIVING THROUGH WATER
Do not drive quickly through standing water, especially if the depth is
unknown. Traction or brake capability may be limited and if the ignition
system gets wet, your engine may stall. Water may also enter your
engine’s air intake and severely damage your engine.
If driving through deep or standing water is unavoidable, proceed very
slowly. Never drive through water that is higher than the bottom of the
hubs (for trucks) or the bottom of the wheel rims (for cars).
Once through the water, always try the brakes. Wet brakes do not stop
the vehicle as effectively as dry brakes. Drying can be improved by
moving your vehicle slowly while applying light pressure on the brake
pedal.

the engine must relearn its idle and fuel trim strategy for optimum
driveability and performance. To begin this process:
1. With the vehicle at a complete stop, set the parking brake.
2. Put the gearshift in P (Park), turn off all accessories and start the
engine.
3. Run the engine until it reaches normal operating temperature.
4. Allow the engine to idle for at least one minute.
5. Turn the A/C on and allow the engine to idle for at least one minute.
6. With your foot on the brake pedal and with the A/C on, put the
vehicle in D (Drive) and allow the engine to idle for at least one minute.
7. Drive the vehicle to complete the relearning process.
•The vehicle may need to be driven 16 km (10 miles) or more to
relearn the idle and fuel trim strategy.
•If you do not allow the engine to relearn its idle trim, the idle
quality of your vehicle may be adversely affected until the idle
trim is eventually relearned.
If the battery has been disconnected or a new battery has been installed,
the clock and the preset radio stations must be reset once the battery is
reconnected.
•Always dispose of automotive
batteries in a responsible manner.
Follow your local authorized
standards for disposal. Call your
local authorized recycling center
to find out more about recycling
automotive batteries.
