Starting the Engine
Starting in Cold Weather at High
Altitude (Above 8,000 feet/
2,400 meters)

weather. The thinner air found at
high altitude above 8,000 feet
(2,400 meters) adds to the problem.
Use the following procedure:

Driving
1. Turn off all electrical accessories
to reduce the drain on the battery.
2. Push the accelerator pedal half-
way to the floor and hold it there
while starting the engine. Do not
hold the ignition key in START
(III) for more than 15 seconds.
When the engine starts, release
the accelerator pedal gradually as
the engine speeds up and smooths
out.
3. If the engine fails to start in step 2,
push the accelerator pedal to the
floor and hold it there while you
try to start the engine for no more
than 15 seconds. If the engine
does not start, return to step 2.
