.Poor fuel quality can causeinefficient engine operation andpoor driveability, which may goaway once the engine is warmedup. If this occurs, change thefuel brand. It may require at
least one full tank of the properfuel to turn the light off. SeeFuel0198.
If the light remains on, see yourdealer.
Emissions Inspection and
Maintenance Programs
If the vehicle requires an EmissionsInspection/Maintenance test, thetest equipment will likely connect tothe vehicle's Data LinkConnector (DLC).
The DLC is under the instrumentpanel to the left of the steeringwheel. Connecting devices that arenot used to perform an EmissionsInspection/Maintenance test or toservice the vehicle may affectvehicle operation. SeeAdd-OnElectrical Equipment0212.Seeyour dealer if assistance is needed.
The vehicle may not passinspection if:
.The light is on when the engineis running.
.The light does not come onwhen the ignition is in ON/RUNwhile the engine is off.
.Critical emission control systemshave not been completelydiagnosed.

This display shows the currentdistance traveled in eitherkilometers (km) or miles (mi) sincethe last reset for each trip odometer.Both trip odometers can be used atthe same time.
Each trip odometer can be reset to
zero separately by pressingVwhile
the desired trip odometer isdisplayed.
The trip odometer has a featurecalled the retro-active reset. Thiscan be used to set the trip odometerto the number of kilometers (miles)driven since the ignition was last
turned on. This can be used if thetrip odometer is not reset at thebeginning of the trip.
To u s e t h e r e t r o - a c t i v e r e s e t f e a t u r e ,
press and holdVfor at least
four seconds. The trip odometer willdisplay the number ofkilometers (km) or miles (mi) drivensince the ignition was last turned onand the vehicle was moving. Oncethe vehicle begins moving, the tripodometer will accumulate mileage.For example, if the vehicle wasdriven 8 km (5 miles) before it isstarted again, and then theretro-active reset feature isactivated, the display will show 8 km(5 miles). As the vehicle beginsmoving, the display will thenincrease to 8.1 km (5.1 miles),8.2 km (5.2 miles), etc.
If the retro-active reset feature isactivated after the vehicle is started,but before it begins moving, thedisplay will show the number ofkilometers (km) or miles (mi) thatwere driven during the last ignitioncycle.
Fuel Range
Press3until FUEL RANGE
displays. This display shows theapproximate number of remainingkilometers (km) or miles (mi) thevehicle can be driven withoutrefueling. The display will showLOW if the fuel level is low.
The fuel range estimate is based onan average of the fuel economyover recent driving history and theamount of fuel remaining in the fueltank. This estimate will change ifdriving conditions change. Forexample, if driving in traffic andmaking frequent stops, this displaymay read one number, but if thevehicle is driven on a freeway, thenumber may change even thoughthe same amount of fuel is in thefuel tank. This is because differentdriving conditions produce differentfuel economies. Generally, freewaydriving produces better fueleconomy than city driving.
If the vehicle is low on fuel, theFUEL LEVEL LOW message will bedisplayed. SeeFuel SystemMessages011 5.

.Allow greater following distanceand watch for slippery spots. Icypatches can occur on otherwiseclear roads in shaded areas.The surface of a curve or anoverpass can remain icy whenthe surrounding roads are clear.Avoid sudden steeringmaneuvers and braking whileon ice.
.Turn off cruise control.
Blizzard Conditions
Stop the vehicle in a safe place andsignal for help. Stay with the vehicleunless there is help nearby.If possible, use RoadsideAssistance. SeeRoadsideAssistance Program0316.Togethelp and keep everyone in thevehicle safe:
.Turn on the hazard warningflashers.
.Tie a red cloth to an outsidemirror.
{Warning
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
carbon monoxide (CO), which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle is stuck in snow:
.Clear snow from the base ofthe vehicle, especially anyblocking the exhaust pipe.
.Open a window about 5 cm(2 in) on the vehicle sidethat is away from the wind,to bring in fresh air.
.Fully open the air outlets onor under the instrumentpanel.
.Adjust the climate controlsystem to circulate the airinside the vehicle and set

Certification/Tire Label
AvehiclespecificCertification/
Tire label is attached to the
center pillar (B-pillar). The label
may show the size of the
vehicle's original tires and the
inflation pressures needed to
obtain the gross weight capacity
of the vehicle. This is called
Gross Vehicle Weight Rating
(GVWR). The GVWR includes
the weight of the vehicle, all
occupants, fuel, and cargo.
The Certification/Tire label also
may show the maximum weights
for the front and rear axles,
called Gross Axle Weight Rating
(GAWR). To find out the actual
loads on the front and rear
axles, you need to go to a weigh
station and weigh the vehicle.

178 Driving and Operating
Operate the engine andtransmission gently to allow theoil to warm up and lubricate allmoving parts.
When the Low Fuel warninglamp is on and the FUELLEVEL LOW message isdisplayed in the DriverInformation Center (DIC), theComputer-Controlled CrankingSystem is disabled to preventpossible vehicle componentdamage. When this happens,hold the ignition switch in theSTART position to continueengine cranking.
Caution
Cranking the engine for long
periods of time, by returning the
ignition to the START position
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not startafter 5-10 seconds, especiallyin very cold weather (below✓18 °C or 0 °F), it could beflooded with too muchgasoline. Try pushing theaccelerator pedal all the way tothe floor and holding it there asyou hold the key in START forup to 15 seconds. Wait at least15 seconds between each try,to allow the cranking motor tocool down. When the enginestarts, let go of the key andaccelerator. If the vehicle startsbriefly but then stops again, dothe same thing. This clears theextra gasoline from the engine.Do not race the engineimmediately after starting it.Operate the engine andtransmission gently until the oilwarms up and lubricates allmoving parts.
