STARTING AND OPERATING 427
10. Start the engine.
11. Release the parking brake.
12. Shift the transmission into DRIVE, release the brakepedal, and check that the vehicle operates normally.
NOTE:
• Steps 3 and 4 are requirements that must be met before pushing the button to shift out of NEUTRAL (N), and must
continue to be met until the shift has been completed. If
any of these requirements are not met before pushing the
button or are no longer met during the shift, the
NEUTRAL (N) indicator light will flash continuously until
all requirements are met or until the button is released.
• The ignition must be in the ON/RUN mode for a shift to take place and for the position indicator lights to be oper -
able. If the ignition is not in the ON/RUN mode, the shift
will not take place and no position indicator lights will be
on or flashing.
• A flashing NEUTRAL (N) position indicator light indi -
cates that shift requirements have not been met.DRIVING TIPS
Driving On Slippery Surfaces
Acceleration
Rapid acceleration on snow covered, wet, or other slippery
surfaces may cause the driving wheels to pull erratically to
the right or left. This phenomenon occurs when there is a
difference in the surface traction under the rear (driving)
wheels.
Driving Through Water
Driving through water more than a few inches/centimeters
deep will require extra caution to ensure safety and prevent
damage to your vehicle.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the rear
wheels. You could lose control of the vehicle and
possibly have a collision. Accelerate slowly and carefully
whenever there is likely to be poor traction (ice, snow,
wet, mud, loose sand, etc.).5
