Remote Vehicle Start
Your vehicle may have a remote start feature. This
feature allows you to start the engine from outside the
vehicle. It may also start the vehicle’s heating or air
conditioning systems. When you start your vehicle using
the remote start feature, the climate control system
will come on and adjust the interior to the temperature
settings that you left it set to when you turned the
vehicle off.
Laws in some communities may restrict the use of
remote starters. For example, some laws may require a
person using remote start to have the vehicle in view
when doing so. Check local regulations for any
requirements on remote starting of vehicles.
Do not use the remote start feature if your vehicle is low
on fuel. Your vehicle may run out of fuel.
The remote start feature provides two separate starts
per ignition cycle, each with 10 minutes of engine
running time.
After your vehicle’s engine has been started two times
using the remote vehicle start button, the vehicle’s
ignition switch must be turned to ON/RUN and then back
to LOCK/OFF using the key before the remote start
procedure can be used again. SeeIgnition Positions on
page 3-19 for information regarding the ignition
positions on your vehicle. If your vehicle has the remote start feature, the RKE
transmitter functions will have an increased range
of operation. However, the range may be less while the
vehicle is running.
There are other conditions which can affect the
performance of the transmitter, see
Remote Keyless
Entry (RKE) System on page 3-3 for additional
information.
/(Remote Start): This button will be on the RKE
transmitter if you have remote start.
To start the vehicle using the remote start feature, do
the following:
1. Aim the transmitter at the vehicle.
2. Press and release
Q, then immediately press and
hold
/until the vehicle’s turn signal lamps flash.
When the vehicle starts, the parking lamps will turn
on and remain on while the engine is running.
The vehicle’s doors will be locked.
3. If it is the first remote start since the vehicle has been driven, repeat these steps, while the engine
is running, to extend the time by 10 minutes for the
engine to continue to run.
After entering the vehicle after a remote start, insert and
turn the key to ON/RUN to drive the vehicle.

Ashtray(s) and Cigarette Lighter
The vehicle may have an ashtray and cigarette lighter.
To use the lighter, located on the instrument panel
below the climate controls, push it in all the way and
let go. When it is ready, it will pop back out by itself.
Notice:Holding a cigarette lighter in while it is
heating will not allow the lighter to back away from
the heating element when it is hot. Damage from
overheating may occur to the lighter or heating
element, or a fuse could be blown. Do not hold a
cigarette lighter in while it is heating. Do not use
equipment exceeding maximum amperage rating
of 15 amperes.
To clean the center console ashtray, remove the entire
ashtray and empty it.
Notice: If papers, pins, or other ammable items
are put in the ashtray, hot cigarettes or other
smoking materials could ignite them and possibly
damage the vehicle. Never put ammable items
in the ashtray.

Engine Coolant Temperature
Warning Light
This light comes on briefly
while starting the vehicle.
If it does not, have the vehicle serviced by the
dealer/retailer. If the system is working normally
the indicator light goes off.
Notice: Driving with the engine coolant temperature
warning light on could cause the vehicle to overheat.
See Engine Overheating on page 6-27 . The vehicle’s
engine could be damaged, and it might not be
covered by the vehicle warranty. Never drive with
the engine coolant temperature warning light on.
The engine coolant temperature warning light comes on
when the engine has overheated.
If this happens pull over and turn off the engine as soon
as possible. See Engine Overheating on page 6-27
for more information.
Tire Pressure Light
For vehicles with a tire
pressure monitoring
system, this light comes
on briefly when the engine
is started. It provides
information about tire
pressures and the Tire
Pressure Monitoring
System.
When the Light is On Steady
This indicates that one or more of the tires are
significantly underinflated.
A tire pressure message in the Driver Information
Center (DIC), can accompany the light. See Driver
Information Center (DIC) on page 4-35 for more
information. Stop and check the tires as soon as it is safe
to do so. If underinflated, inflate to the proper pressure.
See Ination - Tire Pressure on page 6-55 for more
information.

Turn Signals When Towing a Trailer
The arrows on the instrument panel flash whenever
signaling a turn or lane change. Properly hooked up, the
trailer lamps also flash, telling other drivers the vehicle
is turning, changing lanes or stopping.
When towing a trailer, the arrows on the instrument
panel flash for turns even if the bulbs on the trailer are
burned out. For this reason you may think other
drivers are seeing the signal when they are not. It is
important to check occasionally to be sure the
trailer bulbs are still working.
Driving on Grades
Notice:Do not tow on steep continuous grades
exceeding 6 miles (9.6 km). Extended, higher
than normal engine and transmission temperatures
may result and damage the vehicle. Frequent
stops are very important to allow the engine and
transmission to cool.
Reduce speed and shift to a lower gear beforestarting
down a long or steep downgrade. If the transmission is
not shifted down, the brakes might have to be used so
much that they would get hot and no longer work well.
On a long uphill grade, shift down and reduce the
vehicle’s speed to around 45 mph (70 km/h) to reduce
the possibility of the engine and the transmission
overheating. Vehicles can tow in D (Drive). Shift the transmission to
a lower gear if the transmission shifts too often under
heavy loads and/or hilly conditions.
Pay attention to the engine coolant gage. If the indicator
is in the red area, turn off the air conditioning to reduce
engine load. See
Engine Overheating on page 6-27 .
When towing under severe conditions such as hot
ambient temperatures or steep grades, the vehicle may
experience more transmission shifting. A COOLING
MODE ON message may also appear in the DIC. This
alerts the driver that the shifting mode is in progress
and is aiding engine cooling. See DIC Warnings
and Messages on page 4-38 DIC Warnings and
Messages for more information.Parking on Hills
{WARNING:
Parking the vehicle on a hill with the trailer
attached can be dangerous. If something goes
wrong, the rig could start to move. People can be
injured, and both the vehicle and the trailer can be
damaged. When possible, always park the rig on a
flat surface.
5-38

If parking the rig on a hill:1. Press the brake pedal, but do not shift into P (Park) yet for an automatic transmission, or into gear for a
manual transmission. Turn the wheels into the
curb if facing downhill or into traffic if facing uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply the parking brake, and then shift into P (Park) for an automatic
transmission or R (Reverse) for a manual
transmission.
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply the regular brakes and hold the pedal down while you:
•Start the engine.
•Shift into a gear.
•Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
The vehicle needs service more often when pulling a
trailer. See Scheduled Maintenance on page 7-3
for more on this. Things that are especially important in
trailer operation are automatic transmission fluid (do
not overfill), engine oil, drive belt, cooling system
and brake system.
Each of these is covered in this manual, and the Index
will help to find them quickly. When trailering, it is a good
idea to review this information before starting the trip.
Check periodically to see that all hitch nuts and bolts are
tight.
Engine Cooling When Trailer Towing
The cooling system may temporarily overheat during
severe operating conditions. See Engine Overheating on
page 6-27.
Towing a Trailer (Manual
Transmission)
Do not tow a trailer if the vehicle is equipped with a
manual transmission.

{WARNING:
Heater and radiator hoses, and other engine parts,
can be very hot. Do not touch them. If you do, you
can be burned.
Do not run the engine if there is a leak. If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
If there seems to be no leak, with the engine on, check
to see if the electric engine cooling fan is running. If
the engine is overheating, the fan should be running. If
it is not, your vehicle needs service. Notice:
Engine damage from running the engine
without coolant is not covered by the warranty.
Notice: Using coolant other than DEX-COOL
®can
cause premature engine, heater core, or radiator
corrosion. In addition, the engine coolant could
require changing sooner, at 50 000 km (30,000 miles)
or 24 months, whichever occurs rst. Any repairs
would not be covered by the vehicle warranty.
Always use DEX-COOL
®(silicate-free) coolant in the
vehicle.
