gradients by depressing the accelerator.
The clutch may overheat if you hold the vehicle
stationary on uphill gradients by depressing the
accelerator pedal. If the clutch overheats, a

Rocking the vehicle free
Shifting back and forth between transmission
positions h and k can help to free up the
vehicle if it gets stuck in mud or snow. The vehi-
cle's engine management system limits the
speed to a maximum of 5 mph (9 km/h) when
shifting back and forth. To shift repeatedly
between transmission positions h and k,
move the DIRECT SELECT lever up and down
past the point of resistance.
