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

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.

CAUTION!

Do not attempt to push or tow your vehicle to get it

started. Vehicles equipped with an automatic trans-
mission 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.

To prevent damage to the starter, do not continu-

ously crank the engine for more than 15 seconds at
a time. Wait 10 to 15 seconds before trying again.

After Starting
The idle speed is controlled automatically and it will

decrease as the engine warms up.
