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. SeeClimate Control System on
page 3-23for additional information.
Laws in some local 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.
/(Remote Vehicle Start):This button will be on the
RKE transmitter if you have remote start.
An increased range of operation is provided with the RKE
transmitter that has the remote vehicle start button. The
vehicle can be started from approximately 197 feet (60 m)
away. However, the operating range may be less while
the engine is running and you will need to be closer to
your vehicle to turn it off than you were to turn it on.
Do not use the remote start feature if your vehicle is low
on fuel. Your vehicle may run out of fuel.

If this light is on and not ashing, the TCS and
potentially the ESC system have been disabled. Check
your DIC messaging to determine which feature(s) is
no longer functioning and whether it is because of
the driver turning off the feature(s), or the system may
not be working properly and your vehicle requires
service. If the TCS is disabled, wheel spin will not be
limited. If the ESC system is disabled, the system
will not aid in maintaining vehicle directional control. In
either case, adjust your driving accordingly.
If the light is on and ashing, the TCS or the ESC
system is actively working. Check the DIC messaging
for details to determine which system is working. If
the LOW TRACTION message appears, the system is
limiting wheel spin. If the ESC ACTIVE message
appears, the system is aiding in maintaining vehicle
directional control.
SeeElectronic Stability Control (ESC) on page 4-10and
Traction Control System (TCS) on page 4-6for more
information.
SeeDIC Warnings and Messages on page 3-48for
more information on the messages associated with this
light.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 5-26for more information.
Notice:Driving with the engine coolant temperature
warning light on could cause your vehicle to
overheat. SeeEngine Overheating on page 5-26.

Engine Coolant Temperature Gage
Your vehicle has an
engine coolant temperature
gage. With the ignition
turned to RUN, this gage
shows the engine
coolant temperature.
If the gage pointer moves into the red area, your 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.
SeeEngine Overheating on page 5-26.
Tire Pressure Light
Your vehicle may have a
tire pressure light.
This light comes on briey when the engine is started

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
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 your vehicle. Frequent
stops are very important to allow the engine and
transmission to cool.
When towing under severe conditions such as hot
ambient temperatures or steep grades, your 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. SeeDIC Warnings
and Messages on page 3-48DIC Warnings and
Messages for more information.
Reduce speed and shift to a lower gearbeforeyou 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.Pay attention to the engine coolant gage. If the indicator
is in the red area, turn off the air conditioning to
reduce engine load. SeeEngine Overheating on
page 5-26.
Parking on Hills
{CAUTION:
You really should not park your vehicle, with a
trailer attached, on a hill. If something goes
wrong, your rig could start to move. People
can be injured, and both your vehicle and the
trailer can be damaged.
But if you ever have to park your rig on a hill, here is
how to do it:
1. Apply your regular brakes, but do not shift into
PARK (P) for an automatic transmission, or into
gear for a manual transmission. When parking
uphill, turn your wheels away from the curb. When
parking downhill, turn your wheels into the curb.
2. Have someone place chocks under the trailer
wheels.
4-41

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 your
parking brake, and then shift into PARK (P) for
an automatic transmission or REVERSE (R) for a
manual transmission.
5. Release the regular brakes.
When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
Start your 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
Your vehicle will need service more often when you are
pulling a trailer. SeeScheduled Maintenance on
page 6-4for more on this. Things that are especially
important in trailer operation are automatic transmission
uid (do not overll), engine oil, drive belt, cooling
system and brake system.
Each of these is covered in this manual, and the Index
will help you nd them quickly. If you are trailering,
it is a good idea to review this information before you
start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. SeeEngine Overheating on
page 5-26.
