Engine Oil Pressure Gauge
Indicates engine oil pressure. The needle
should stay in the normal operating range,
between the L and H marks. If the needle
falls below the normal range, stop your
vehicle, turn off the engine and check the
engine oil level. Add oil if needed. If the oil
level is correct and the gauge displays
incorrectly, have your vehicle checked by
an authorized dealer.
Engine Coolant Temperature
Gauge WARNING:
Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap
with a thick cloth to prevent the
possibility of scalding and slowly remove
the cap. Failure to follow this instruction
could result in personal injury.
Indicates engine coolant temperature. At
normal operating temperature, the level
indicator is in the normal range. If the
engine coolant temperature exceeds the
normal range, stop your vehicle as soon as
possible, switch off the engine and let the
engine cool.
Fuel Gauge
The fuel gauge indicates about how much
fuel is in the fuel tank.
The arrow adjacent to the fuel pump
symbol indicates on which side of your
vehicle the fuel filler door is located.
Note: The fuel gauge may vary slightly
when your vehicle is moving or on a slope. Low Fuel Reminder
A low fuel level reminder displays and
sounds when the distance to empty
reaches
50 mi (80 km), 25 mi (40 km),
10 mi (20 km) and 0 mi (0 km).
Note: The low fuel reminder can appear at
different fuel gauge positions depending on
fuel economy conditions. This variation is
normal.
Distance to Empty
Indicates the approximate distance your
vehicle can travel on the fuel remaining in
the tank. Changes in driving pattern can
cause the value to not only decrease but
also increase or stay constant for periods
of time.
Configurable Gauge
Transmission Fluid Temperature Gauge
Indicates transmission fluid temperature.
At normal operating temperature, the level
indicator is in the normal range. If the
transmission fluid temperature exceeds
the normal range, stop your vehicle as soon
as possible and verify the airflow is not
restricted by snow or debris blocking
airflow through the grille.
To lower the transmission temperature
into the normal range, alter the severity of
your driving conditions. Operating the
transmission for extended periods with the
gauge in the higher than normal area may
cause internal transmission damage. If the
gauge continues to show high
temperatures, see an authorized dealer.
Voltmeter
Displays electrical system voltage.

occurring. Increased exhaust gas
temperatures could damage the catalytic
converter or other vehicle components.
Drive in a moderate fashion (avoid heavy
acceleration and deceleration) and have
your vehicle checked as soon as possible.

cranked and automatically turns off if no
malfunctions are present. However, if after
15 seconds it flashes eight times, this
indicates that your vehicle is not ready for
Inspection and Maintenance (I/M) testing.
See Emission Law (page 46).

GENERAL INFORMATION
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 can be toxic.
Always open the garage door before you
start the engine. 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.
If you disconnect the battery, your vehicle
may exhibit some unusual driving
characteristics for approximately
5 mi
(8 km) after you reconnect it. This is
because the engine management system
must realign itself with the engine. You
can disregard any unusual driving
characteristics during this period.
The powertrain control system meets all
Canadian interference-causing equipment
standard requirements regulating the
impulse electrical field or radio noise.
When you start the engine, avoid pressing
the accelerator pedal before and during
operation. Only use the accelerator pedal
when you have difficulty starting the
engine. IGNITION SWITCH
A
(accessory) - Allows the electrical
accessories, such as the radio, to operate
while the engine is not running.
Note: Do not leave the ignition key in this
position for too long. This could cause your
vehicle battery to lose charge.
B
(lock) - Locks the gearshift lever and
allows key removal.
C
(off) - The ignition is off.
Note: When you switch the ignition off and
leave your vehicle, do not leave your key in
the ignition. This could cause your vehicle
battery to lose charge.
D
(on) - All electrical circuits are
operational and the warning lamps and
indicators illuminate.
E
(start) - Cranks the engine.
STARTING A GASOLINE
ENGINE
When you start the engine, the idle speed
increases, this helps to warm up the
engine. If the engine idle speed does not
slow down automatically, have your
vehicle checked by an authorized dealer.

Before starting the engine check the
following:
•
Make sure all occupants have fastened
their safety belts.
• Make sure the headlamps and
electrical accessories are off.
• Make sure the parking brake is on.
• Make sure the transmission is in park
(P) or neutral (N).
• Turn the ignition key to the on position.
Note: Do not touch the accelerator pedal.
1. Fully press the brake pedal.
2. Turn the key to the start position to start the engine. Release the key when
the engine starts.
Note: The engine may continue cranking
for up to 15 seconds or until it starts.
Note: If you cannot start the engine on the
first try, wait for a short period and try again.
Failure to Start
If you cannot start the engine after three
attempts, wait 10 seconds and follow this
procedure:
1. Fully press the brake pedal.
2. Fully press the accelerator pedal and hold it there.
3. Start the engine.
Stopping the Engine When Your
Vehicle is Stationary
1. Shift into park (P) or neutral (N).
2. Turn the key to the off position.
3. Apply the parking brake. Stopping the Engine When Your
Vehicle is Moving WARNING: Switching off the
engine when the vehicle is still moving
will result in a loss of brake and steering
assistance. The steering will not lock, but
higher effort will be required. When the
ignition is switched off, some electrical
circuits, including air bags, warning lamps
and indicators may also be off. If the
ignition was turned off accidentally, you
can shift into neutral (N) and re-start the
engine.
1. Put the transmission into neutral (N) and use the brakes to bring your vehicle
to a safe stop.
2. When your vehicle has stopped, shift into park (P) or neutral (N) and switch
the ignition off.
3. Apply the parking brake.
Guarding Against Exhaust Fumes WARNING:
If you smell exhaust
fumes inside your vehicle, have your
vehicle checked by your authorized
dealer immediately. Do not drive your
vehicle if you smell exhaust fumes.
Carbon monoxide is present in exhaust
fumes. Take precautions to avoid its
dangerous effects.
Important Ventilating Information
If you stop your vehicle and then leave the
engine idling for long periods of time, we
recommend that you do one of the
following:
• Open the windows at least 1 in (3 cm).
• Set your climate control to outside air.
