Section 2 Features and Controls
2-1

The engine will shut off automatically after 10 minutes,
unless a time extension has been done or the
vehicle’s key is inserted into the ignition switch and
turned to ON/RUN.
To manually shut off a remote start, do any of the
following.
Aim the RKE transmitter at the vehicle and press
and release the remote start button.
Turn on the hazard warning ashers.
Turn the ignition switch out of LOCK/OFF position
and then back to LOCK/OFF.
After the engine has been started two times, or one
time with a time extension, the vehicle’s ignition must be
turned to ON/RUN using the key before the remote
start procedure can be used again. SeeIgnition
Positions on page 2-22for information regarding the
ignition positions on your vehicle.
The remote vehicle start feature will not operate if any
of the follow occur:
The remote start system is disabled through the DIC.
The vehicle’s key is in the ignition.
The vehicle’s hood is open.
The hazard warning ashers are on.
The check engine light is on. SeeMalfunction
Indicator Lamp on page 3-39.
The engine coolant temperature is too high.
The oil pressure is low.
Two remote vehicle starts, or one start with a time
extension, have already been provided for that
ignition cycle.
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/retailer to add the
manufacturer’s remote vehicle start feature.
If your vehicle has the remote start ready feature, your
RKE 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/retailer 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/retailer in the area where you will be
parking your vehicle. The dealer/retailer can give you
the best advice for that particular area.

If the light stays on, or comes on when you are driving
a SERVICE STABILITRAK message will appear in
the DIC. This indicates that there may be a problem with
the Electronic Stability Control (ESC) system and your
vehicle may need service. When this warning light
is on and the SERVICE STABILITRAK message
appears on the DIC, the ESC system will not assist you
in controlling the vehicle. Adjust your driving accordingly.
When the system is active, the light will ash while
the system is assisting you in controlling the vehicle.
You may also feel or hear the system working.
This is normal.
