Some fuel stations, particularly those inhigh altitude areas, offer fuels posted asregular unleaded gasoline with an octanerating below 87. The use of these fuelscould result in engine damage that will notbe covered by the vehicle warranty.
For best overall vehicle and engineperformance, premium fuel with an octanerating of 91 or higher is recommended. Theperformance gained by using premium fuelis most noticeable in hot weather as wellas other conditions, for example whentowing a trailer. See Towing (page 219).
Do not be concerned if the enginesometimes knocks lightly. However, if theengine knocks heavily while using fuel withthe recommended octane rating, contactan authorized dealer to prevent any enginedamage.
We recommend Top Tier detergentgasolines, where available to help minimizeengine deposits and maintain optimalvehicle and engine performance. Foradditional information, refer towww.toptiergas.com.
Note:Use of any fuel for which the vehiclewas not designed can impair the emissioncontrol system, cause loss of vehicleperformance, and cause damage to theengine which may not be covered by thevehicle Warranty.
Do not use:
•Diesel fuel.
•Fuels containing kerosene or paraffin.
•Fuel containing more than 15% ethanolor E85 fuel.
•Fuels containing methanol.
•Fuels containing metallic-basedadditives, including manganese-basedcompounds.
•Fuels containing the octane boosteradditive, methylcyclopentadienylmanganese tricarbonyl (MMT).
•Leaded fuel, using leaded fuel isprohibited by law.
The use of fuels with metallic compoundssuch as methylcyclopentadienylmanganese tricarbonyl (commonly knownas MMT), which is a manganese-basedfuel additive, will impair engineperformance and affect the emissioncontrol system.
FUEL FILLER FUNNEL
LOCATION
The fuel filler funnel is under the luggagecompartment floor covering.
RUNNING OUT OF FUEL
Running out of fuel can cause damage notcovered by the vehicle Warranty.
If your vehicle runs out of fuel:
•Add a minimum of 1.3 gal (5 L) of fuelto restart the engine.
•You may need to switch the ignitionfrom off to on several times afterrefueling to allow the fuel system topump the fuel from the tank to theengine. When restarting, cranking timetakes a few seconds longer thannormal.
Note:If your vehicle is on a steep slope,more fuel may be required.

GENERAL INFORMATION
Note: Occasional brake noise is normal. Ifa metal-to-metal, continuous grinding orcontinuous squeal sound is present, thebrake linings may be worn-out and anauthorized dealer should check them. If thevehicle has continuous vibration or shudderin the steering wheel while braking, anauthorized dealer should check your vehicle.
Note: Brake dust may accumulate on thewheels, even under normal drivingconditions. Some dust is inevitable as thebrakes wear and does not contribute tobrake noise. See Cleaning the Wheels(page 298).
Wet brakes result in reduced brakingefficiency. Gently press the brake pedal afew times when driving from a car wash orstanding water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedalbecomes stuck or entrapped, apply steadyand firm pressure to the brake pedal toslow the vehicle and reduce engine power.If you experience this condition, apply thebrakes and bring your vehicle to a safestop. Move the transmission to park (P),switch the engine off and apply the parkingbrake. Inspect the accelerator pedal forany interference. If none are found and thecondition persists, have your vehicle towedto the nearest authorized dealer.
Emergency Brake Assist
Emergency brake assist detects when youbrake heavily by measuring the rate atwhich you press the brake pedal. Itprovides maximum braking efficiency aslong as you press the pedal. Emergencybrake assist can reduce stopping distancesin critical situations.
Note:Depending on applicable laws andregulations in the country for which yourvehicle was originally built, your brake lampscould flash during heavy braking. Followingthis, your hazard lights may also flash whenyour vehicle comes to a stop.
Anti-lock Brake System
This system helps you maintain steeringcontrol during emergency stops by keepingthe brakes from locking.
This lamp momentarilyilluminates when you switch theignition on. If the light does notilluminate during start up, remains on orflashes, the anti-lock braking system maybe disabled. Have the system checked byan authorized dealer. If the anti-lock brakesystem is disabled, normal braking is stilleffective.
See Warning Lamps and Indicators(page 93).
Note:Indicators vary depending on region.
This lamp also illuminatesmomentarily when you switchthe ignition on to confirm thelamp is functional. If it does notilluminate when you switch theignition on, or begins to flash atany time, have the system checked by anauthorized dealer. If the brake warninglamp illuminates with the parking brakereleased, have the system checkedimmediately.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
The anti-lock brake system does noteliminate the risks when:
•You drive too closely to the vehicle infront of you.
•Your vehicle is hydroplaning.

HILL START ASSIST
WARNING: The system does notreplace the parking brake. When youleave your vehicle, always apply theparking brake and shift the transmissioninto park (P) for automatic transmissionor first gear for manual transmission.
WARNING: You must remain inyour vehicle when the system turns on.At all times, you are responsible forcontrolling your vehicle, supervising thesystem and intervening, if required.Failure to take care may result in the lossof control of your vehicle, seriouspersonal injury or death.
WARNING: The system will turnoff if a malfunction is apparent. Failureto take care may result in the loss ofcontrol of your vehicle, serious personalinjury or death.
The system makes it easier to pull awaywhen your vehicle is on a slope without theneed to use the parking brake.
When the system activates, your vehicleremains stationary on a slope for a fewseconds after you release the brake pedal.This allows you time to move your footfrom the brake to the accelerator pedal.The brakes release when the engine hasdeveloped sufficient torque to prevent yourvehicle from rolling down the slope. Thisis an advantage when pulling away on aslope, for example from a car park ramp,traffic lights or when reversing uphill intoa parking space.
The system activates on any slope thatcauses your vehicle to roll.
Note: There is no warning lamp to indicatethe system is either on or off.
Using Hill Start Assist
1.Press the brake pedal to bring yourvehicle to a complete standstill. Keepthe brake pedal pressed and shift intofirst gear when facing uphill or reverse(R) when facing downhill.
2.The system activates if the sensorsdetect that your vehicle is on a slope.
3.When you remove your foot from thebrake pedal, your vehicle remains onthe slope without rolling away for a fewseconds. This hold time increases if youare in the process of driving off.
4.Pull away in the normal manner.
