160 STARTING AND OPERATING
STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both inside and outside mirrors, and fasten your seat belts.
WARNING!
Do not leave children or animals inside parked vehicles in hot weather. Interior heat build up may cause serious injury or death.
Manual Transmission
Apply the parking brake, place the gearshift control lever in N (Neutral) and depress the clutch pedal before starting vehicle. This vehicle is equipped with a clutch interlocking ignition system. It will not start unless the clutch pedal is pressed to the floor.
WARNING!
You or others around you could be injured if you attempt to start the engine with a manual transmission in gear — your vehicle will move. Remember, always push the clutch pedal in fully and shift into N (Neutral) before attempting to start the engine.
Automatic Transmission
Start the engine with the selector lever in the N (Neutral) or P (Park) position. Apply the brake before shifting to any driving range.
Normal Starting
Normal starting of either a cold or a warm engine is obtained without pumping or depressing the accelerator pedal. Turn the key to the START position and release when the engine starts. If the engine fails to start within 10 seconds, turn the key to the OFF position, wait 5seconds, then repeat the normal starting procedure.
STARTING AND OPERATING 161
Extreme Cold Weather (below -20°F or -29°C)
To insure reliable starting at these temperatures, use of an externally powered electric engine block heater (available from your dealer) is recommended.
If Engine Fails to Start
If the engine fails to start after you have followed the "Normal Starting" or "Extreme Cold Weather" procedures, it may be flooded. Push the accelerator pedal all the way to the floor and hold it there while cranking the engine. This should clear any excess fuel in case the engine is flooded.
CAUTION!
To prevent damage to the starter, do not crank the engine for more than 15 seconds at a time. Wait 10 to 15 seconds before trying again.
If the engine has been flooded, it may start to run, but not have enough power to continue running when the key is released. If this occurs, continue cranking with the accelerator pedal pushed all the way to the floor. Release the accelerator pedal and the key once the engine is running smoothly.
If the engine shows no sign of starting after two 15 second periods of cranking with the accelerator pedal held to the floor, the "Normal Starting" or "Extreme Cold Weather" procedures should be repeated.
162 STARTING AND OPERATING
WARNING!
Never pour fuel or other flammable liquids into the throttle body air inlet opening in an attempt to start the vehicle. This could result in a flash fire causing serious personal injury.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms engine coolant and permits quicker starts in cold weather. Connect the cord to a standard 110-115 volt AC electrical outlet with a grounded, three wire extension cord. The engine block heater cord is found under the hood clipped to the tie rodbetween the radiator grille and the dash panel.
After Starting
The idle speed will automatically decrease as the engine warms up.
CAUTION!
WARNING!
Remember to disconnect the cord before driving. Damage to the 110-115 volt AC electrical cord could cause electrocution.
Long periods of engine idling, especially at high engine speeds can cause excessive exhaust temperatures which can damage your vehicle. Do not leave your vehicle unattended with the engine running.
Use the heater when temperatures below 0°F (-18°C) are expected to last for several days.
STARTING AND OPERATING 163
TRANSMISSION SHIFTING
5-Speed Manual Overdrive Transmission
Follow the shift pattern on the gearshift knob.
NOTE: The backup lights will come on when your vehicle is in reverse gear and the ignition is in the ON position.
WARNING!
When parking your vehicle, always leave a manual transmission in first gear and apply the parking brake fully to guard against vehicle movement and possible injury or damage. Never use any gear as a substitute for the parking brake.
CAUTION!
To drive as safely as possible and to prolong the life of your manual transmission, follow these tips:
Before shifting from a forward gear into reverse, or from reverse to a forward gear, stop vehicle completely. Otherwise, transmission damage may result.
Do not operate at sustained high engine or road speeds in lower gears. Engine damage may result.
164 STARTING AND OPERATING
Do not downshift into a low gear while traveling at too high a speed for that gear. Engine, clutch, or transmission damage may result.
Do not rest your foot on the clutch pedal. This causes heat buildup and damages the clutch.
When you slow down or go up a grade, downshift as speed requires or the engine may overheat.
Never hold the vehicle stopped on a hill by using the clutch pedal. The clutch may be damaged.
During cold weather, you may experience increased effort in shifting until the transmission fluid warms up. This is normal.
Push in the clutch pedal completely when shifting. Otherwise, transmission or clutch damage may result.
When "rocking" a stuck vehicle by shifting between a forward gear and reverse, do not spin wheels faster than 15 mph (24 km/h), or drivetrain damage may result.
• The manual transmission may be equipped with a "Reverse Blocker" to prevent inadvertent shifts from 5th gear to Reverse. If you experience difficulty shifting into "Reverse", make sure that you are not inadvertently moving the shift lever toward 5th gear when shifting into "Reverse."
Recommended Manual Transmission Shifting Speeds
The "Shift Indicator Light" in the instrument cluster reminds you when to shift to the next higher gear (4.0L Only). The manufacturer recommends that you use the SIL for normal driving. The desired shift speeds are listed in the chart below.
