Driving for Better Fuel Economy
Driving habits can affect fuel mileage. Here are somedriving tips to get the best fuel economy possible.
•Avoid fast starts and accelerate smoothly.
•Brake gradually and avoid abrupt stops.
•Avoid idling the engine for long periods of time.
•When road and weather conditions are appropriate,
use cruise control, if equipped.
•Always follow posted speed limits or drive more
slowly when conditions require.
•Keep vehicle tires properly inflated.
•Combine several trips into a single trip.

What Will You See After an Airbag
Inflates?
After the frontal airbags and seat-mounted side impactairbags inflate, they quickly deflate, so quickly thatsome people may not even realize an airbag inflated.Roof-rail airbags may still be at least partially inflated forsome time after they deploy. Some components ofthe airbag module may be hot for several minutes. Forlocation of the airbag modules, seeWhat Makes anAirbag Inflate? on page 2-65.
The parts of the airbag that come into contact with youmay be warm, but not too hot to touch. There maybe some smoke and dust coming from the vents in thedeflated airbags. Airbag inflation does not preventthe driver from seeing out of the windshield or beingable to steer the vehicle, nor does it prevent people fromleaving the vehicle.
{WARNING:
When an airbag inflates, there may be dust in the
air. This dust could cause breathing problems for
people with a history of asthma or other breathing
trouble. To avoid this, everyone in the vehicle
should get out as soon as it is safe to do so. If
you have breathing problems but cannot get out of
the vehicle after an airbag inflates, then get fresh
air by opening a window or a door. If you
experience breathing problems following an airbag
deployment, you should seek medical attention.
The vehicle has a feature that may automatically unlockthe doors, turn on the interior lamps and hazardwarning flashers, and shut off the fuel system after theairbags inflate. You can lock the doors, turn off theinterior lamps and hazard warning flashers by using thecontrols for those features.

{WARNING:
A crash severe enough to inflate the airbags may
have also damaged important functions in the
vehicle, such as the fuel system, brake and
steering systems, etc. Even if the vehicle appears
to be drivable after a moderate crash, there may
be concealed damage that could make it difficult
to safely operate the vehicle.
Use caution if you should attempt to restart the
engine after a crash has occurred.
In many crashes severe enough to inflate the airbag,windshields are broken by vehicle deformation.Additional windshield breakage may also occur from theright front passenger airbag.
•Airbags are designed to inflate only once. After an
airbag inflates, you will need some new parts forthe airbag system. If you do not get them, the airbagsystem will not be there to help protect you inanother crash. A new system will include airbagmodules and possibly other parts. The servicemanual for your vehicle covers the need to replaceother parts.
•The vehicle has a crash sensing and diagnostic
module which records information after a crash.SeeVehicle Data Recording and Privacy onpage 8-18andEvent Data Recorders on page 8-19.
•Let only qualified technicians work on the airbag
systems. Improper service can mean that anairbag system will not work properly. See yourdealer/retailer for service.
Passenger Sensing System
The vehicle has a passenger sensing system for theright front passenger position. The passenger airbagstatus indicator will be visible on the overhead consolewhen the vehicle is started.
The words ON and OFF, or the symbol for on and off,are visible during the system check. If you are usingremote start, if equipped, to start the vehicle froma distance, you may not see the system check.

Remote Vehicle Start
The remote vehicle starting feature allows you to startthe engine from outside of the vehicle. It also startsup the vehicle’s automatic climate control system. Whenthe remote start system is active, the climate controlsystem will heat and cool the inside of the vehicleaccording to the previous settings of the system beforeturning the vehicle off. The rear window defoggerwill be turned on by the climate control system when itis cold outside. If the vehicle has heated seats, theywill also turn on when it is cold outside. SeeHeated andVentilated Seats on page 2-5for additional information.Cooled seats are not activated during a remote start.Normal operation of the climate control system willreturn after the key is turned to ON/RUN. SeeDualClimate Control System on page 4-36.
Laws in some communities may restrict the use ofremote starters. For example, some laws may require aperson using remote start to have the vehicle in viewwhen doing so. Check local regulations for anyrequirements on remote starting of vehicles.
Do not use the remote start feature if your vehicle is lowon fuel. Your vehicle may run out of fuel.
If your vehicle has the remote start feature, the RKEtransmitter functions will have an increased rangeof operation. However, the range may be less while thevehicle is running.
There are other conditions which can affect theperformance of the transmitter, seeRemote KeylessEntry (RKE) System Operation on page 3-4foradditional information.
/(Remote Start):This button will be on the
RKE transmitter if you have remote start.
To start the vehicle using the remote start feature:
1. Aim the transmitter at the vehicle.
2. Press and release the transmitter’s lock button,then immediately press and hold the transmitter’sremote start button until the turn signal lightsflash or if the vehicle’s lights are not visible, pressand hold the remote start button for at leastfour seconds. Pressing the remote start buttonagain after the vehicle has started will turn off theignition.
When the vehicle starts, the parking lamps will turnon and remain on while the vehicle is running.The vehicle’s doors will be locked.
3. If it is the first remote start since the vehicle has beendriven, repeat these steps, while the engine is stillrunning, to extend the engine running time by10 minutes. Remote start can be extended one time.
