For example, if the lock button and then the remote
start buttons are pressed again after the vehicle
has been running for ve minutes, 10 minutes are
added, allowing the engine to run for 15 minutes.
The additional 10 minutes are considered a second
remote start.
Once two remote starts, or a single remote start with
one time extension has been done, the vehicle must be
started with the key.
After the key is removed from the ignition, the vehicle
can be started using the remote start feature again.
The vehicle cannot be started using the remote
start feature if the key is in the ignition, the hood is not
closed, or if there is an emission control system
malfunction.
Also, the engine will turn off during a remote start if the
coolant temperature gets too high or if the oil pressure
gets low.Vehicles that have the remote vehicle start feature are
shipped from the factory with the remote vehicle
start system enabled. The system may be enabled or
disabled through the DIC if your vehicle has DIC
buttons. See “REMOTE START” underDIC Vehicle
Customization (With DIC Buttons) on page 3-75
for additional information. If your vehicle does not have
DIC buttons, see your dealer/retailer to enable or
disable the remote start system.
Remote Start Ready
If your vehicle does not have the remote start feature, it
will have the remote start ready feature. This feature
allows your dealer/retailer to add the manufacturer’s
remote start feature.
See your dealer/retailer if you would like to add the
manufacturer’s remote start feature to your vehicle.

Engine Coolant Heater
The engine coolant heater, if available, can help in cold
weather conditions at or below 0°F (−18°C) for easier
starting and better fuel economy during engine warm-up.
Plug in the coolant heater at least four hours before
starting your vehicle. An internal thermostat in the
plug-end of the cord may exist which will prevent
engine coolant heater operation at temperatures
above 0°F (−18°C).
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The
cord is located on the driver’s side of the engine
compartment, it is routed around the windshield
washer uid reservoir.
3. Plug the cord into a normal, grounded 110-volt AC
outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts. If you do not, it could be
damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer/retailer in the area where you will be
parking your vehicle. The dealer/retailer can give you
the best advice for that particular area.

2. Set the driver’s and passenger’s temperature.
To nd your comfort setting, start with a 73°F (22°C)
temperature setting and allow about 20 minutes
for the system to regulate. Use the driver’s or
passenger’s temperature buttons to adjust the
temperature setting as necessary. If you choose
the temperature setting of 60°F (15°C), the system
remains at the maximum cooling setting. If you
choose the temperature setting of 90°F (32°C),
the system remains at the maximum heat setting.
Choosing either maximum setting will not cause
the vehicle to heat or cool any faster.
Do not cover the solar sensor located on the top of
the instrument panel near the windshield. This sensor
regulates air temperature based on sun load and also
turns on your vehicle’s headlamps. For more information
on the solar sensor, see “Sensors” later in this section.
To avoid blowing cold air in cold weather, the system
delays turning on the fan until warm air is available.
The length of delay depends on the engine coolant
temperature. Press the fan switch to override this delay
and change the fan to a selected speed.

Engine Coolant Temperature
Warning Light
The engine coolant
temperature warning light
will come on when the
engine has overheated.
If this happens you should pull over and turn off the
engine as soon as possible. SeeEngine Overheating
on page 5-25for more information.
Notice:Driving with the engine coolant temperature
warning light on could cause your vehicle to

be covered by your warranty. Never drive with
the engine coolant temperature warning light on.
This light will also come on briey when starting
your vehicle. If it does not, have your vehicle serviced.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
Under normal driving conditions the gage will read
210°F (100 °C) or less. If the gage pointer is near
260°F (125 °C), the engine is too hot.
It means that your engine coolant has overheated.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.

ENGINE OVERHEATED STOP ENGINE
Notice:If you drive your vehicle while the engine
is overheating, severe engine damage may occur.
If an overheat warning appears on the instrument
panel cluster and/or DIC, stop the vehicle as soon
as possible. SeeEngine Overheating on page 5-25
for more information.
This message displays and a continuous chime
sounds if the engine cooling system reaches unsafe
temperatures for operation. Stop and turn off the vehicle
as soon as it is safe to do so to avoid severe damage.
This message clears when the engine has cooled
to a safe operating temperature.
ENGINE POWER IS REDUCED
This message displays and a chime sounds when
the cooling system temperature gets too hot and the
engine further enters the engine coolant protection
mode. SeeEngine Overheating on page 5-25for
further information.
This message also displays when the vehicle’s engine
power is reduced. Reduced engine power can affect
the vehicle’s ability to accelerate. If this message is on,but there is no reduction in performance, proceed to
your destination. The performance may be reduced
the next time the vehicle is driven. The vehicle may be
driven at a reduced speed while this message is on,
but acceleration and speed may be reduced. Anytime
this message stays on, the vehicle should be taken
to your dealer/retailer for service as soon as possible.

Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal asher and/or extra wiring. Check
with your dealer/retailer. The arrows on your instrument
panel will ash whenever you signal a turn or lane
change. Properly hooked up, the trailer lamps will also
ash, telling other drivers you’re about to turn,
change lanes or stop.
When towing a trailer, the arrows on your instrument
panel will ash for turns even if the bulbs on the trailer
are burned out. Thus, you may think drivers behind
you are seeing your signal when they are not. It
is important to check occasionally to be sure the trailer
bulbs are still working.
Driving on Grades
Your vehicle is designed primarily as a passenger and
load carrying vehicle. If you tow a trailer, your vehicle
will require more frequent maintenance due to the
additional load. Because of the added load of the trailer,
your vehicle’s engine may overheat on hot days,
when going up a long or steep grade with a trailer. If the
engine coolant temperature gage indicates overheating,
turn off the air conditioning to reduce engine load,
pull off the road and stop in a safe spot.
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you do not shift
down, you might have to use your brakes so much that
they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your
speed to around 55 mph (88 km/h) to reduce the
possibility of the engine and the transmission
overheating.
