GARAGE DOOR OPENER
LIMITATIONS
Canadian radio-frequency laws require
transmitter signals to time-out (or quit) after
several seconds – which may not be long
enough for HomeLink to pick up the signal.
U.S. gate operators time-out in the same
manner.
Note: If programming a garage door opener
or gate operator, it is advised to unplug the
device during the “cycling” process to
prevent possible overheating. PROGRAMMING THE GARAGE
DOOR OPENER TO YOUR HAND-
HELD TRANSMITTER
This process is to program your in-vehicle
HomeLink function button with your
hand-held transmitter.
Note:
The programming steps below assume
you will be programming HomeLink that was
not previously programmed. If your
HomeLink was previously programmed, you
may need to erase your HomeLink buttons.
See
Clearing the Garage Door Opener
(page 176). 1. With your vehicle parked outside of the
garage, switch your ignition to the on
position, but do not start your vehicle.
2. Press and release one of the three HomeLink function buttons that you
would like to program.
3. Hold your hand-held garage door transmitter 1–3 in (2–8 cm) away from the
HomeLink button you want to program.
4. Press and hold the hand-held transmitter
button you want to program while
watching the indicator light on HomeLink.
Continue to hold the hand-held button
until the HomeLink indicator light flashes
rapidly or is continuously on.

Gate Operator / Canadian
Programming
Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit) after
several seconds of transmission – which may
not be long enough for HomeLink to pick up
the signal during programming. Similar to
this Canadian law, some U.S. gate operators
“time-out” in the same manner.
Note:
If programming a garage door opener
or gate operator, it is advised to unplug the
device during the “cycling” process to
prevent possible overheating.
1. Press and release, every two seconds, your hand-held transmitter until the
HomeLink indicator light changes to a
rapidly blinking or continuously on light.
2. Release the hand-held transmitter button.

Make sure that you allow sufficient distance
between your vehicle and other vehicles for
stopping. On ice and snow, you should drive
more slowly than usual. In emergency
stopping situations, steadily apply the brake.
Your vehicle has a four wheel anti-lock brake
system, do not pump the brake pedal. See
Anti-Lock Braking System Limitations (page
218
).
Note: If your vehicle gets stuck driving on
snow and ice, it may be rocked out by
shifting between forward and reverse gears,
stopping between shifts in a steady pattern.
Press lightly on the accelerator in each gear. Note:
Do not rock your vehicle if the engine
is not at normal operating temperature, as
damage to the transmission may occur.
Note: Do not rock your vehicle for more than
a minute, as damage to the transmission
and tires may occur or the engine may
overheat.

ELECTRIC POWER STEERING
Electric Power Steering Precautions
WARNING: The electric power
steering system has diagnostic checks that
continuously monitor the system. If a fault
is detected, a message displays in the
information display. Stop your vehicle as
soon as it is safe to do so. Switch the vehicle off. After at least 10 seconds, switch
the vehicle on and watch the information
display for a steering system warning
message. If a steering system warning
message returns, have the system checked
as soon as possible.
WARNING:
If the system detects an
error, you may not feel a difference in the
steering, however a serious condition may
exist. Have your vehicle checked as soon
as possible. Failure to do so may result in
loss of steering control. Adapt your speed and driving behavior
according to reduced steering assist.
Extreme continuous steering may increase
the effort to steer. This occurs to prevent
internal overheating and damage to the
steering system. If this occurs, you will not
lose the ability to steer your vehicle manually
nor will it cause damage to the system.
Normal steering and driving allows the
system to cool down and steering assist
returns to normal.
Note:
There is no fluid reservoir to check or
fill.

REDUCED ENGINE PERFORMANCE
WARNING: If you continue to drive
your vehicle when the engine is
overheating, the engine could stop without
warning. Failure to follow this instruction
could result in the loss of control of your
vehicle.
If the engine coolant temperature gauge
needle moves to the upper limit position, the
engine is overheating.
See What Is the
Engine Coolant Temperature Gauge (page
139).
You must only drive your vehicle for a short
distance if the engine overheats. The
distance you can travel depends on ambient
temperature, vehicle load and terrain. The
engine continues to operate with limited
power for a short period of time.
If the engine temperature continues to rise,
the fuel supply to the engine reduces. The
air conditioning switches off and the engine
cooling fan operates continually. 1. Gradually reduce your speed and stop
your vehicle as soon as it is safe to do
so.
2. Immediately switch the engine off to prevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level.
See Checking
the Coolant (page 340).
5. Have your vehicle checked as soon as possible.
COLD WEATHER PRECAUTIONS
The functional operation of some
components and systems can be affected at
temperatures below approximately
-13°F
(-25°C).
BREAKING-IN
You need to break in new tires for
approximately
300 mi (480 km). During this
time, your vehicle may exhibit some unusual
driving characteristics. DRIVING THROUGH WATER WARNING:
Do not drive through
flowing or deep water as you may lose
control of your vehicle.
Note: Driving through standing water can
cause vehicle damage.
Note: Engine damage can occur if water
enters the air filter.
Before driving through standing water, check
the depth. Never drive through water that is
higher than the bottom of the front rocker
area of your vehicle.

To top up the coolant level do the following:
1. Unscrew the cap slowly. Any pressure
escapes as you unscrew the cap.
2. Add enough prediluted coolant to reach
the correct level.
Note: We do not recommend the use of
recycled coolant.
3. Replace the coolant reservoir cap. Turn the cap clockwise until it contacts the
hard stop.
4. Check the coolant level in the coolant reservoir the next few times you drive
your vehicle. If necessary, repeat step 2.
If you have to add more than 1.1 qt (1 L) of
engine coolant per month, have your vehicle
checked as soon as possible. Operating an
engine with a low level of coolant can result
in engine overheating and possible engine
damage.
In case of emergency, you can add a large
amount of water without engine coolant in
order to reach a vehicle service location.
Service your vehicle as soon as possible. Water alone, without engine coolant, can
cause engine damage from corrosion,
overheating or freezing.
Do not use the following as a coolant
substitute, as they can cause engine damage
from overheating or freezing:
•
Alcohol.
• Methanol.
• Brine.
• Any coolant mixed with alcohol or
methanol antifreeze.
Do not add extra inhibitors or additives to
the coolant. These can be harmful and
compromise the corrosion protection of the
coolant.
Severe Climates
If you drive in extremely cold climates, you
may need to increase the coolant
concentration above 50%. Note:
A coolant concentration of 60%
provides improved freeze point protection.
Coolant concentrations above 60% decrease
the overheat protection characteristics of
the coolant and could cause engine
damage.
If you drive in extremely hot climates, you
may need to decrease the coolant
concentration to 40%.
Note: Coolant concentrations below 40%
decrease the freeze and corrosion protection
characteristics of the coolant and could
cause engine damage.
Coolant Change
Change the coolant at specific mileage
intervals. Refer to the scheduled
maintenance information.
See Normal
Scheduled Maintenance (page 463).
Note: Dispose of used coolant in the
appropriate manner.
Follow your community's regulations and
standards for recycling and disposing of
automotive fluids.
