Maneuvering
To maneuver in tight areas, e.g. when pulling into a 
parking space, control the vehicle speed by gradually 
releasing the brakes. Accelerate gently and never 
abruptly step on the accelerator.
To rock a vehicle out of soft ground (mud or snow), 
alternately shift from forward to reverse, while applying 
only slight partial throttle.
Rocking a vehicle free in this manner may cause the 
ABS malfunction indicator lamp to come on. Turn off 
and restart the engine to clear the malfunction 
indication.
Stopping
For brief stops, e.g. at traffic lights, leave the 
transmission in gear and hold vehicle with the service 
brake.
For longer stops with the engine idling, shift into “N” 
or “P” and hold the vehicle with the service brake.
When stopping the vehicle on an uphill gradient, do not 
hold it with the accelerator, use the brake. This avoids 
unnecessary transmission heat build up.
Wa r n i n g !
Getting out of your vehicle with the selector lever 
not fully engaged in position “P” is dangerous. 
Also, when parked on an incline, position “P” alone 
may not prevent your vehicle from moving, 
possibly hitting people or objects.Always set the parking brake in addition to shifting 
to position “P”.When parked on an incline, also turn front wheel 
towards the road curb.When leaving the vehicle always remove the key 
from the steering lock, and lock the vehicle. Do not 
leave children unattended in the vehicle, or with 
access to an unlocked vehicle. Children could move 
the selector lever from position “P”, which could 
result in an accident or serious injury.
