Your vehicle can climb a 16 inch (40.6 cm) vertical step.
Step climbing is best done by approaching the step at
an angle rather than straight on.

Brake and Accelerator Operation
Techniques for Off-Road Driving

For logs, walls, rocks, severe ditches,
hills, sand, etc.

1. Bring the vehicle to a complete stop. Do not rev

the engine.

2. Select the proper transmission and transfer

case gear range; usually FIRST (1) gear,
Four-Wheel-Low Lock for such obstacles.

3. If wheel spin is experienced, maintain steady

throttle, with your foot off the brake pedal, to
allow the Traction Control System (TCS) to control
the wheel spin. TCS will not operate if the brakes
are applied, even slightly.

4. If wheel spin cannot be controlled by the system,

fully press the brake pedal with your left foot so
all wheel spin is halted.

5. Back away from the obstacle so that a new

approach can be tried.

6. As the first wheel crosses the obstacle, be prepared

to alternate the brake and accelerator pedal to
maintain control and avoid tire drop-off from
obstacles. Repeat this process for the other wheels.
