After entering the vehicle during a remote start, insertand turn the key to ON/RUN to drive the vehicle.
If the vehicle is left running it will automatically shut offafter 10 minutes unless a time extension has been done.
To manually shut off a remote start:
•Aim the RKE transmitter at the vehicle and press
the remote start button until the parking lampsturn off.
•Turn on the hazard warning flashers.
•Turn the ignition switch on and then off.
The remote vehicle start feature provides two separatestarts, each with 10 minutes of engine running, or itprovides one start with 10 minutes of engine running thatmay be extended 10 more minutes. If you press andrelease the transmitter lock button and then press andhold the remote start button on the RKE transmitteragain before the first 10 minutes of engine running timehas expired, 10 minutes are added to the remainingminutes. For example, if the lock button and thenthe remote start buttons are pressed again afterfive minutes of the engine run time, 10 minutes areadded and you now have 15 minutes of engine running.The added ten minutes are considered a secondremote vehicle start.
Once two remote starts or a single start with a timeextension have been used, the vehicle must be startedwith the ignition key before you can use the remotestart feature again.
The remote vehicle start feature will not operate if thekey is in the ignition, the hood is not closed, or if there isan emission control system malfunction.
The engine will turn off during a remote vehicle start ifthe coolant temperature gets too high, or the oil pressureis too low.
Your vehicle was shipped from the factory with theremote vehicle start system enabled. The system maybe disabled through the Driver Information Center (DIC).See “REMOTE START” underDIC VehicleCustomization on page 4-80for additional information.
SeeEngine Exhaust on page 3-34for important safetyinformation when using remote start in a closed garage.

Engine Coolant Heater
The engine coolant heater can provide easier startingand better fuel economy during engine warm-up in coldweather conditions at or below 0°F (!18°C). Vehicleswith an engine coolant heater should be pluggedin at least four hours before starting.
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 sideof the engine, behind the transmission dipstick/fluidfill location and next to the engine.
3. Plug it into a normal, grounded 110-volt AC outlet.
{WARNING:
Plugging the cord into an ungrounded outlet could
cause an electrical shock. Also, the wrong kind of
extension cord could overheat and cause a fire.
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 andstore the cord as it was before to keep it awayfrom moving engine parts and prevent damage.
The length of time the heater should remain plugged independs on several factors. Ask a dealer/retailer inthe area where you will be parking the vehicle for thebest advice on this.

Engine Coolant Temperature Gage
This gage shows theengine coolanttemperature.
It indicates when the engine has warmed up and if thecooling system is operating properly. If the gagepointer moves into the shaded area, the engine coolantis too hot and the engine coolant temperature warninglight comes on. SeeEngine Overheating on page 6-27for more information.
Tire Pressure Light
For vehicles with a tire pressure monitoring system, thislight comes on briefly when the engine is started. Itprovides information about tire pressures and the TirePressure Monitoring System.
When the Light is On Steady
This indicates that one or more of the tires aresignificantly underinflated.
A tire pressure message in the Driver InformationCenter (DIC), can accompany the light. SeeDriverInformation Center (DIC) on page 4-61for moreinformation. Stop and check the tires as soon as it issafe to do so. If underinflated, inflate to the properpressure. SeeInflation - Tire Pressure on page 6-54formore information.
