FUEL AND REFUELING
PRECAUTIONS
WARNING: Do not overfill the fueltank. The pressure in an overfilled tankmay cause leakage and lead to fuel sprayand fire.
WARNING: The fuel system may beunder pressure. If you hear a hissing soundnear the fuel filler inlet, do not refuel untilthe sound stops. Otherwise, fuel may sprayout, which could cause serious personalinjury.
WARNING: Fuels can cause seriousinjury or death if misused or mishandled.
WARNING: Fuel may containbenzene, which is a cancer-causing agent.
WARNING: When refueling alwaysshut the engine off and never allow sparksor open flames near the fuel tank fillervalve. Never smoke or use a cell phonewhile refueling. Fuel vapor is extremelyhazardous under certain conditions. Avoidinhaling excess fumes.
WARNING: Read and follow all theinstructions on the pump island.
Follow these guidelines when refueling:
•Extinguish all smoking materials and anyopen flames before refueling yourvehicle.
•Switch the engine off before refueling.
•Automotive fuels can be harmful or fatalif swallowed. Fuel is highly toxic and ifswallowed can cause death or permanentinjury. If fuel is swallowed immediatelycall a physician, even if no symptoms areimmediately apparent. The toxic effectsof fuel may not be apparent for hours.
•Avoid inhaling fuel vapors. Inhaling fuelvapor can lead to eye and respiratorytract irritation. In severe cases, excessiveor prolonged breathing of fuel vapor cancause serious illness and permanentinjury.
•Avoid getting fuel in your eyes. If yousplash fuel in your eyes, immediatelyremove contact lenses, if worn, flush withwater for 15 minutes and seek medicalattention. Failure to seek proper medicalattention could lead to permanent injury.
•Fuels can be harmful if absorbed throughthe skin. If you splash fuel on your skin,clothing or both, promptly removecontaminated clothing and thoroughlywash your skin with soap and water.Repeated or prolonged skin contactcauses skin irritation.

COLD WEATHER PRECAUTIONS
The functional operation of somecomponents and systems can be affected attemperatures below approximately -13°F(-25°C).
DRIVING ON SNOW AND ICE
WARNING: If you are driving inslippery conditions that require tire chainsor cables, then it is critical that you drivecautiously. Keep speeds down, allow forlonger stopping distances and avoidaggressive steering to reduce the chancesof a loss of vehicle control which can leadto serious injury or death. If the rear endof your vehicle slides while cornering, steerin the direction of the slide until you regaincontrol of your vehicle.
On ice and snow, you should drive moreslowly than usual. Your vehicle has a fourwheel anti-lock brake system, do not pumpthe brake pedal. See Anti-Lock BrakingSystem Limitations (page 232).
BREAKING-IN
Your vehicle requires a break-in period. Forthe first 1,000 mi (1,600 km), avoid driving athigh speeds, heavy braking, aggressiveshifting or using your vehicle to tow. Duringthis time, your vehicle may exhibit someunusual driving characteristics.
DRIVING ECONOMICALLY
The following helps to improve fuelconsumption:
•Drive smoothly, accelerate gently andanticipate the road ahead to avoid heavybraking.
•Regularly check your tire pressures andmake sure that they are inflated to thecorrect pressure.
•Follow the recommended maintenanceschedule and carry out therecommended checks.
•Plan your journey and check the trafficbefore you set off. It is more efficient tocombine errands into a single tripwhenever possible.
•Avoid idling the engine in cold weatheror for extended periods. Start the engineonly when you are ready to set off.
•Do not carry unnecessary weight in yourvehicle as extra weight wastes fuel.
•Do not add unnecessary accessories tothe exterior of your vehicle, for examplerunning boards. If you use a roof rack,remember to fold it down or remove itwhen not in use.
•Do not shift into neutral when you arebraking or when your vehicle is slowingdown.
•Shut all windows when driving at highspeeds.
•Switch off all electric systems when notin use, for example air conditioning. Makesure that you unplug any accessoriesfrom the auxiliary power points when notin use.
