STARTING AND STOPPING THE
ENGINE – PRECAUTIONS
WARNING: Extended idling at high
engine speeds can produce very high
temperatures in the engine and exhaust
system, creating the risk of fire or other
damage. WARNING:
Do not park, idle or drive
your vehicle on dry grass or other dry
ground cover. The emission system heats
up the engine compartment and exhaust
system, creating the risk of fire. WARNING:
Do not start the engine
in a closed garage or in other enclosed
areas. Exhaust fumes are toxic. Always
open the garage door before you start the
engine. Failure to follow this instruction
could result in personal injury or death. WARNING:
Do not use starting fluid,
for example ether, in the air intake system.
Such fluid could cause immediate
explosive damage to the engine and
possible personal injury. WARNING: Exhaust leaks may result
in entry of harmful and potentially lethal
fumes into the passenger compartment. If
you smell exhaust fumes inside your
vehicle, have your vehicle inspected
immediately. Do not drive if you smell
exhaust fumes.
The powertrain control system meets all
Canadian interference-causing equipment
standard requirements regulating the
impulse electrical field or radio noise.
If you stop your vehicle and leave the engine
idling for long periods, we recommend that
you do one of the following:
• Open the windows at least
1 in (2.5 cm).
• Set your climate control to outside air. PUSH BUTTON IGNITION SWITCH
Switching the Ignition Off
When the ignition is on or in accessory mode,
press the push button ignition switch once
without your foot on the brake pedal.
Switching the Ignition to Accessory
Mode
When the ignition is off, press the push
button ignition switch once without your foot
on the brake pedal.
All electrical circuits and accessories are
operational and the warning lamps and
indicators illuminate.

AUTOMATIC TRANSMISSION
PRECAUTIONS
WARNING: Always fully apply the
parking brake and make sure you shift into
park (P). Failure to follow this instruction
could result in personal injury or death. WARNING:
Do not apply the brake
pedal and accelerator pedal
simultaneously. Applying both pedals
simultaneously for more than a few
seconds will limit engine performance,
which may result in difficulty maintaining
speed in traffic and could lead to serious
injury. WARNING:
When your vehicle is
stationary, keep the brake pedal fully
pressed when shifting gears. Failure to
follow this instruction could result in
personal injury, death or property damage. Note:
Do not use supplemental transmission
fluid additives, treatments, or cleaning
agents. Failure to follow this instruction could
result in vehicle damage not covered by the
vehicle warranty.
AUTOMATIC TRANSMISSION
POSITIONS
Park (P) WARNING:
Move the transmission
selector lever to park (P) only when your
vehicle is stationary.
This position locks the driveline. Come to a
complete stop before putting your vehicle
into and out of park (P).
The electric parking brake could apply when
you shift to park (P) without the brake pedal
fully pressed. The electric parking brake
applies when you shift to park (P) on large
slopes. The electric parking brake releases
with the drive away release function.
See
Electric Parking Brake (page 221). Note:
A warning tone sounds if you open the
driver door and you have not shifted the
transmission selector to park (P).
Reverse (R) WARNING:
Move the transmission
selector lever to reverse (R) only when your
vehicle is stationary and the engine is at
idle speed.
This position allows your vehicle to move
backward. Come to a complete stop before
shifting into and out of reverse (R).
Neutral (N) WARNING: In neutral (N) your vehicle
has the ability to roll freely. If you intend to
leave your vehicle, make sure you apply
the parking brake.
This position allows your vehicle to roll free.
Hold the brake pedal down when in this
position.

BRAKE PRECAUTIONS
WARNING: Driving your vehicle with
the warning lamp on is dangerous. A
significant decrease in braking
performance may occur. It may take you
longer to stop your vehicle. Have your
vehicle checked as soon as possible.
Driving extended distances with the
parking brake engaged can cause brake
failure and the risk of personal injury.
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes. ANTI-LOCK BRAKING SYSTEM
Anti-Lock Braking System Limitations
The anti-lock braking system does not
eliminate the risk of crash when:
•
You drive too closely to the vehicle in
front of you.
• Your vehicle is hydroplaning.
• You take corners too fast.
• The road surface is poor.
Note: If the system activates, the brake
pedal could pulse and could travel further.
Maintain pressure on the brake pedal.
BRAKE OVER ACCELERATOR
In the event the accelerator pedal becomes
stuck or entrapped, apply steady and firm
pressure to the brake pedal to slow the
vehicle and reduce engine power. If you
experience this condition, apply the brakes
and bring your vehicle to a safe stop. Move the transmission to park (P), switch the
engine off and apply the parking brake.
Inspect the accelerator pedal for any
interference. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.
LOCATING THE BRAKE FLUID
RESERVOIR
See
Under Hood Overview (page 334).
CHECKING THE BRAKE FLUID WARNING: Do not use any fluid other
than the recommended brake fluid as this
will reduce brake efficiency. Use of
incorrect fluid could result in the loss of
vehicle control, serious personal injury or
death.
