3. Start the vehicle.
If it is necessary to use the above procedure to move the gearshift, it is
possible that a fuse has blown or the vehicle’s brakelamps are not
operating properly. Refer toFuses and relaysin theRoadside
emergencieschapter.
Do not drive your vehicle until you verify that the brakelamps
are working.
If your vehicle gets stuck in mud or snow it may be rocked out by
shifting from forward and reverse gears, stopping between shifts, in a
steady pattern. Press lightly on the accelerator in each gear.
Do not rock the vehicle for more than a few minutes. The
transmission and tires may be damaged or the engine may
overheat.
Always set the parking brake fully and make sure the gearshift is
latched in P (Park). Turn off the ignition 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 dealer or a qualified service technician.

CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
Tire change procedure
Preparing to change the tire
To prevent the vehicle from moving when you change a tire, be
sure the parking brake is set, then block (in both directions) the
wheel that is diagonally opposite (other side and end of the vehicle) to
the tire being changed.
1. Park on a level surface.
2. Activate the warning flashers.
3. Place the gearshift in P (Park).
