WARNING!

Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
axle cannot be started this way. Unburned fuel could
enter the catalytic converter and once the engine has
started, ignite and damage the converter and vehicle.
If the vehicle has a discharged battery, booster cables
may be used to obtain a start from another vehicle.
This type of start can be dangerous if done improp-
erly, so follow the procedure carefully. See Section 6
of this manual for jump-starting instructions.

Extremely Cold Weather (Below

Ϫ

20°F Or

Ϫ

29°C)

To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater (avail-
able from your authorized dealer) is recommended.

If Engine Fails to Start

If the engine fails to start after you have followed the
“Normal Starting” procedure, it may be flooded. Push
the accelerator pedal all the way to the floor and hold it
there. Crank the engine for no more than 15 seconds. This
should clear any excess fuel in case the engine is flooded.
Leave the ignition key in the ON position, release the
accelerator pedal and repeat the “Normal Starting” pro-
cedure.

WARNING!

Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.
