Section 2 Features and Controls
91

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.
The engine will turn off during a remote vehicle
start if the coolant temperature gets too high,
or the oil pressure is too low.
Your 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 259
for additional information.
SeeEngine Exhaust on page 130for important
safety information when using remote start
in a closed garage.
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. See your dealer if you would like to add
the manufacturer’s remote vehicle start feature
to your vehicle.
Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers, especially children, can
easily open the doors and fall out of a
moving vehicle. When a door is
locked, the handle will not open it.
You increase the chance of being
thrown out of the vehicle in a crash if
the doors are not locked. So, wear
safety belts properly and lock the
doors whenever you drive.
CAUTION: (Continued)

Engine Coolant Heater
Your vehicle may have an engine coolant heater.
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 electrical cord is located on the driver’s
side of the engine, behind the transaxle
dipstick/uid ll location and next to the
engine.
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/retailer can give you the best advice for that
particular area.

Warning Light
The engine coolant
temperature warning
light will come on when
the engine is very hot.
This light will also come on briey when the
vehicle is started.
If the light does not go out or comes on and stays
on while driving, there may be a problem with
the cooling system. Driving with engine coolant
temperature light on could cause your vehicle
to overheat, seeOverheated Engine Protection
Operating Mode on page 379. SeeEngine
Overheating on page 377andDIC Warnings and
Messages on page 246for more information.
Engine Coolant Temperature Gage
This gage shows
the engine coolant
temperature.
It indicates when the engine has warmed up and
if the cooling system is operating properly. If
the gage pointer moves into the shaded area,
the engine coolant is too hot and the engine
coolant temperature warning light will come on.
SeeEngine Overheating on page 377for
more information.
