Section 2 Features and Controls
2-1

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 with 10 more minutes. If you press and
release the transmitter lock button and then press and
hold the remote start button, on the remote keyless entry
transmitter, 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 provided, the vehicle must be
started normally with the ignition key to get more remote
vehicle starts.
The remote vehicle start feature will not operate 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 vehicle
start if the coolant temperature gets too high or if the oil
pressure gets low.
Vehicles equipped with 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. See “REMOTE START”
underDIC Vehicle Customization on page 3-52for
additional information.
Remote Start Ready
If your vehicle does not have the remote vehicle start
feature, it may have the remote start ready feature.
This feature allows your dealer to add the
manufacturer’s remote vehicle start feature.
If your vehicle has the remote start ready feature, your
remote keyless entry transmitter will have extended
range that will allow you to lock or unlock your vehicle
from about 195 feet (60 m) away.
See your dealer if you would like to add the
manufacturer’s remote vehicle start feature to your
vehicle.

Engine Coolant Heater
Your vehicle may have this feature. In very cold
weather, 0°F (−18°C) or colder, the engine coolant
heater can help. You will get easier starting and better
fuel economy during engine warm-up. Usually, the
coolant heater should be plugged in a minimum of four
hours prior to starting your vehicle. At temperatures
above 32°F (0°C), use of the coolant heater is not
required.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The
cord is attached to the underside of the diagonal
brace, which is located above the engine air
cleaner/lter assembly.
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.
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 in the area where you will be parking
your vehicle. The dealer can give you the best advice
for that particular area.

If it stays on, or comes on when you are driving, there
may be a problem with your traction control system
and your vehicle may need service. When this warning
light is on, the system will not limit wheel spin. Adjust
your driving accordingly.
If the traction control system warning light comes on
and stays on for an extended period of time when
the system is turned on, your vehicle needs service.
