STARTING
Positions of the ignition
1. ACCESSORY, allows the electrical
accessories such as the radio to
operate while the engine is not
running.
2. LOCK, locks the steering wheel,
automatic transmission gearshift
lever and allows key removal. For
vehicle equipped with a manual
transmission, you must depress the
ignition release lever to release the
key.
3. OFF, shuts off the engine and all accessories without locking the
steering wheel. This position also allows the automatic transmission shift
lever to be moved from the P (Park) position without the brake pedal
being depressed.
When the key is in the ignition OFF position, the automatic
transmission shift lever can be moved from the P (Park) position
without the brake pedal depressed. To avoid unwanted vehicle
movement, always set the parking brake.
4. ON, all electrical circuits operational. Warning lights illuminated. Key
position when driving.
5. START, cranks the engine. Release the key as soon as the engine
starts.
Preparing to start your vehicle
Engine starting is controlled by the powertrain control system. This
system meets all Canadian Interference-Causing Equipment standard
requirements regulating the impulse electrical field strength of radio
noise.
When starting a fuel-injected engine, don’t press the accelerator before
or during starting. Only use the accelerator when you have difficulty
starting the engine. For more information on starting the vehicle, refer to
Starting the enginein this chapter.

BRAKES
Occasional brake noise is normal. If a metal-to-metal, continuous grinding
or continuous squeal sound is present, the brake linings may be worn-out
and should be inspected by a qualified service technician. If the vehicle
has continuous vibration or shudder in the steering wheel while braking,
the vehicle should be inspected by a qualified service technician.
Four-wheel anti-lock brake system (ABS) (if equipped)
Your vehicle may be equipped with an Anti-lock Braking System (ABS).
This system helps you maintain steering control during emergency stops
by keeping the brakes from locking. Noise from the ABS pump motor
and brake pedal pulsation may be observed during ABS braking; any
pulsation or mechanical noise you may feel or hear is normal.
ABS warning lamp
ABS
TheABSlamp in the instrument cluster momentarily illuminates when
the ignition is turned to ON. If the light does not illuminate during start
up, remains on or flashes, the ABS may be disabled and may need to be
serviced.
Even when the ABS is disabled,
normal braking is still effective. (If
your BRAKE warning lamp
illuminates with the parking brake
released, have your brake system serviced immediately.)
Using ABS
When hard braking is required, apply continuous force on the brake
pedal; do not pump the brake pedal since this will reduce the
effectiveness of the ABS and will increase your vehicle’s stopping
distance. The ABS will be activated immediately, allowing you to retain
full steering control during hard braking and on slippery surfaces.
However, the ABS does not decrease stopping distance.
