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.
Fast Idle System
If equipped, this feature is availableonly with cruise control. The manualfast idle switch is operated using thecruise control buttons on the leftside of the steering wheel.
This system can be used toincrease engine idle speedwhenever the following conditionsare met:
.The parking brake is set.
.The brake pedal is not pressed.
.The vehicle must not be movingand the accelerator must not bepressed.
To c o n t r o l t h e f a s t i d l e :

The engine coolant heater canprovide easier starting and betterfuel economy during enginewarm-up in cold weather conditionsat or below✓18 °C (0 °F). Vehicleswith an engine coolant heatershould be plugged in at least fourhours before starting. An internalthermostat in the plug end of thecord may exist which will preventengine coolant heater operation attemperatures above✓18 °C (0 °F).

Driving and Operating 181
Warning (Continued)
It is dangerous to get out of the
vehicle if the shift lever is not fully
in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the
engine is running. If you have left
the engine running, the vehicle
can move suddenly. You or others
could be injured. To be sure the
vehicle will not move, even when
you are on fairly level ground,
always set the parking brake and
move the shift lever to P (Park).
SeeShifting Into Park0180.
If you are towing a trailer, see
Driving Characteristics and
To w i n g T i p s0202.
If you have to leave the vehicle withthe engine running, be sure thevehicle is in P (Park) and theparking brake is firmly set. After theshift lever is moved into P (Park),hold the regular brake pedal down.Then, see if you can move the shiftlever away from P (Park) without
first pulling it toward you. If you can,it means that the shift lever was notfully locked into P (Park).
Torque Lock
If you are parking on a hill and youdo not shift the transmission intoP(Park) properly, the weight of thevehicle can put too much force onthe parking pawl in thetransmission. It might be difficult topull the shift lever out of P (Park).This is called torque lock. Toprevent torque lock, set the parkingbrake and then shift into P (Park)properly before you leave the driverseat. To find out how, seeShiftingInto Park0180.
When you are ready to drive, movethe shift lever out of P (Park) beforereleasing the parking brake.
If torque lock does occur, you mightneed to have another vehicle pushyours a little uphill to take some ofthe pressure from the parking pawlin the transmission. Then youshould be able to pull the shift leverout of P (Park).
Shifting out of Park
The vehicle has an automatictransmission shift lock controlsystem. You have to fully apply thebrakes before you can shift fromP(Park) when the ignition is in ON/RUN or ACC/ACCESSORY. SeeAutomatic Transmission0183.
The shift lock control system isdesigned to:
.Prevent the ignition key frombeing removed unless the shiftlever is in P (Park).
.Prevent movement of the shiftlever out of P (Park), unless theignition is in ON/RUN or ACC/ACCESSORY and the regularbrake pedal is applied.
The shift lock control system isalways functional except in the caseof a dead battery or low voltage(less than 9 V) battery.
If the vehicle has an unchargedbattery or a battery with low voltage,try charging or jump starting thebattery. SeeJump Starting - NorthAmerica0282.
