When you remove the key from the
ignition switch, the steering wheel
automatically moves fully in and up.

The steering wheel then returns to
its original position when you insert
the key back in the ignition switch.
Steering wheel movement is also
controlled by the driving position
memory system (see page 168).If your vehicle's battery is
disconnected or goes dead, or the
fuse for the power tilt and telescopic
steering wheel is removed, the
power tilt and telescopic steering
wheel system needs to be reset when
you reconnect the battery or install
the fuse.
Insert the key into the ignition
switch, and remove it. The steering
wheel automatically moves fully in
and up to let you know the system is

Your vehicle's starting system has an
auto control mode. When you turn
the ignition switch to the START (III)
position, this feature keeps the
engine's starter motor running until
the engine starts. Follow these
instructions to start the engine:
1. Apply the parking brake.
2. In cold weather, turn off all
electrical accessories to reduce the
drain on the battery.
3. Make sure the shift lever is in
Park. Press on the brake pedal.4. Without touching the accelerator
pedal, turn the ignition switch to
the START (III) position, then
release the ignition switch. You do
not need to hold the ignition
switch in the START (III) position
to start the engine. Depending on
the outside temperature, the
starter motor runs for about 6 to 9
seconds until the engine starts.
If you hold the ignition switch in
the START (III) position for more
than 7 seconds, the starter motor,
depending on the outside
temperature, runs for about 10 to
25 seconds until the engine starts.
If the engine does not start, wait at
least 10 seconds before trying
again.
The immobilizer system protects your
vehicle from theft. If an improperly-
coded key (or other device) is used, the
engine's fuel system is disabled. For
more information, see page 138.
The engine is harder to start in cold
weather. Also, the thinner air found at
altitudes above 8,000 feet (2,400
meters) adds to this problem.
