If the gearshift lever cannot be moved from P (Park) with the brake
pedal depressed, 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.
If your vehicle gets stuck in mud or snow it may be rocked out by
shifting between forward and reverse gears, stopping between shifts, in a
steady pattern. Press lightly on the accelerator in each gear.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transaxle may occur.
Do not rock the vehicle for more than a few minutes or damage
to the transaxle and tires may occur 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.
Driving with an automatic overdrive transaxle with column
gearshift and O/D off switch
Your automatic transaxle electronically controls the shift feel by using an
adaptive learning strategy. This feature is designed to optimize shift
smoothness. It is normal for your transaxle to shift firmly during the first
few hundred kilometers (miles) of operation until the adaptive strategy
has been learned. The adaptive learning strategy is maintained by power
from the battery. When the battery is disconnected or a new battery is
installed, the transaxle must relearn its adaptive strategy. Optimal
shifting will resume within a few hundred kilometers (miles) of
operation.
