Retained Accessory Power (RAP)

Your vehicle may be equipped with a Retained

features on your vehicle to continue to work up to
10 minutes after the ignition key is turned to OFF.
Your radio, power windows and overhead console will
work when the ignition key is in RUN or ACCESSORY.
Once the key is turned from RUN to LOCK, these
features will continue to work for up to 10 minutes or
until a door is opened.

Starting Your Engine

Automatic Transmission
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won't start in any other position – that's a
safety feature. To restart when you're already moving,
use NEUTRAL (N) only. If you have a diesel engine refer
to the diesel supplement for starting procedure.
2-22
Notice: Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.

Manual Transmission

The gear selector should be in neutral and the parking
brake engaged. Hold the clutch pedal to the floor
and start the engine. Your vehicle won't start if the clutch
pedal is not all the way down – that's a safety feature.
