The remote vehicle start feature provides two separate
starts, each with 10 minutes of engine running, or it
provides one start with 10 minutes of engine running
that may be extended 10 more minutes. If the transmitter
lock button is pressed and released and then the
remote start button is pressed and held again before
the rst 10 minutes of engine running time has expired,
10 minutes are added to the remaining minutes.
For example, if the lock button and then the remote
start buttons are pressed again after ve minutes of the
engine run time, 10 minutes are added and you now
have 15 minutes of engine running. The added ten
minutes are considered a second remote vehicle start.
Once two remote starts or a single start with a time
extension have been used, the vehicle must be started
normally before the remote start feature can be used
again.
The remote start feature does not operate if any of the
following occur:
The ignition is in any position other than LOCK/OFF.
A keyless access transmitter is inside the vehicle.
The hood is open.
There is an emission control system malfunction.
The remote start feature is not enabled. See
“Remote Start” underDIC Vehicle Customization on
page 3-72.
The engine turns off during a remote vehicle start if the
coolant temperature gets too high, or the oil pressure
is too low.
This vehicle was shipped from the factory with the
remote vehicle start system enabled. The system may
be disabled through the Driver Information Center (DIC).
See “Remote Start” underDIC Vehicle Customization
on page 3-72for additional information.
If this vehicle has the remote start feature, the RKE
transmitter functions 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, seeRemote Keyless
Entry (RKE) System on page 2-5orKeyless Access
System on page 2-8for additional information.
SeeEngine Exhaust on page 2-50for important safety
information when using remote start in a closed garage.

Engine Coolant Heater
Vehicles with the engine coolant heater can use this
option 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 near the driver side strut
tower.
Remove the plastic cap to access the plug.
3. Plug it 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.
Contact your dealer/retailer for information on how
long to use the heater in your particular area.

Engine Oil Low Add Oil
If the vehicle has an oil level sensor, this message
displays if the oil level in the vehicle is low. Check the
oil level and correct it as necessary. You may need to let
the vehicle cool or warm up and cycle the ignition to
be sure this message clears.
This message clears itself after 10 seconds, until the
next ignition cycle. SeeEngine Oil on page 5-18
for additional information.
Engine Overheated Idle 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. Do not increase the engine speed above
normal idling speed. SeeEngine Overheating
on page 5-37for more information.
This message displays when the engine coolant
temperature is too hot. Stop and allow the vehicle to
idle until it cools down. SeeEngine Coolant

Turn Signals When Towing a Trailer
The arrows on the instrument panel ash whenever
signaling a turn or lane change. Properly hooked up, the
trailer lamps also ash, telling other drivers the vehicle
is turning, changing lanes or stopping.
When towing a trailer, the arrows on the instrument
panel ash 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.
The vehicle has bulb warning lights. When a trailer
lighting system is plugged into the vehicle’s lighting
system, its bulb warning lights may not let the driver
know if one of the lamps goes out. So, when the a trailer
lighting system plugged in, be sure to check the
vehicle and trailer lamps from time to time to be sure
they are all working. Once the trailer lamps are
disconnected, the bulb warning lights can again let the
driver know that one of the vehicle lamps is out.
Driving On Grades
Reduce speed and shift to a lower gearbeforestarting
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. For vehicles with a
manual transmission, it is better not to use the
highest gear.
When towing at high altitude on steep uphill grades,
consider the following: Engine coolant will boil at a lower
temperature than at normal altitudes. If the engine is
turned off immediately after towing at high altitude
on steep uphill grades, the vehicle may show signs
similar to engine overheating. To avoid this, let
the engine run while parked, preferably on level ground,
with the automatic transmission in P (Park) or the
manual transmission in N (Neutral) for a few minutes
before turning the engine off. If the overheat warning
comes on, seeEngine Overheating on page 5-37.
