Warning (Continued)
Do not leave the vehicle when the
engine is running. If you have left
the engine running, the vehicle
can move suddenly. You or others
could be injured. To be sure the
vehicle will not move, even when
you are on fairly level ground,
always set the parking brake and
move the shift lever to P (Park).
See Shifting Into Park 0 172.
Make sure the shift lever is fully in
P (Park) before starting the engine.
The vehicle has an automatic
transmission shift lock control
system. You must fully apply the
brake pedal then press the shift
lever button before you can shift
from P (Park) while the ignition is
on. If you cannot shift out of
P (Park), ease pressure on the shift
lever and push the shift lever all the
way into P (Park) as you maintain
brake application. Then move the
shift lever into another gear. See
Shifting out of Park 0 172.
R : Use this gear to back up.

get out of snow, ice, or sand without
damaging the transmission, see If

not connect with the wheels. To
