GENERAL INFORMATION

WARNINGS

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.

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.

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.

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.

If you disconnect the battery, your vehicle
may exhibit some unusual driving
characteristics for approximately 5 miles
(8 kilometers) 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.

If your vehicle is operated in a heavy snow
storm or blowing snow conditions, the
engine air induction may become partially
clogged with snow and ice. If this occurs,
the engine may experience a significant
reduction in power output. At the earliest
opportunity, clear all the snow and ice
away from the air induction inlet.

STARTING A GASOLINE
ENGINE - 6.2L/6.8L

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.

•

Move the transmission selector lever
to position P.

•

Turn the ignition key to the on position.

Note: Do not touch the accelerator pedal.

1.

Fully depress the brake pedal.

2. Turn the key to the start position to

start your vehicle.

3. When the engine starts, release the

key, then gradually release the
accelerator pedal as the engine speed
increases.

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 depress 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.

When your vehicle has stopped, shift
into park (P) and switch the ignition
off.

2. 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) and switch the ignition
off.

3. Apply the parking brake.

Cold Weather Starting (Flexible
Fuel Vehicles Only)

The starting characteristics of all grades
of E85 ethanol make it unsuitable for use
when ambient temperatures fall below
-0°F (-18°C). Consult your fuel distributor
for the availability of winter grade ethanol.
As the outside temperature approaches
freezing, ethanol fuel distributors should
supply winter grade ethanol, the same as
with unleaded gasoline.

If summer grade ethanol is used in cold
weather conditions, -0°F (-18°C), you may
experience increased cranking times, rough
idle or hesitation until the engine has
warmed up.

You may experience a decrease in
performance when the engine is cold when
operating on E85 ethanol.
