If it is necessary to use the above procedure to move the gearshift lever,
it is possible that a fuse has blown or the vehicle's brakelamps are not
operating properly. Refer to Fuses and relays in the Roadside
Emergencies chapter.
Do not drive your vehicle until you verify that the brakelamps
are working.
Always set the parking brake fully and make sure the gearshift is
latched in P (Park). Turn the ignition to the LOCK position and
remove the key whenever you leave your vehicle.
If the parking brake is fully released, but the brake warning lamp
remains illuminated, the brakes may not be working properly.
See your authorized dealer.
Driving with an automatic overdrive transaxle
Your automatic overdrive transaxle
provides fully automatic operation in
either (Overdrive) or D (Drive).
Driving with the gearshift lever
in (Overdrive) gives the best
fuel economy for normal driving
conditions. For manual control, start
in 1 (First) and then shift manually.
If your vehicle is equipped with a
console-mounted gearshift lever, you
must press the thumb button on the
side of the gearshift lever to move
the gearshift lever from P (Park).
To put your vehicle in gear, start the
engine, depress the brake pedal,
then move the gearshift lever out of
P (Park).
