Off-Road Driving This off-road guide is meant to provide advice for when you drive your vehicle off paved roads. Also, see Braking on page 4-6. Off-road driving can be great fun. But it does have some definite hazards. The greatest of these is the terrain itself. "Off-roading" means you have left the great North American road system behind. Traffic lanes are not marked. Curves are not banked. There are no road signs. Surfaces can be slippery, rough, uphill or downhill. In short, you have gone right back to nature. Off-road driving involves some new skills. And that is why it is very important that you read this guide. You will find many driving tips and suggestions. These will help make your off-road driving safer and more enjoyable. Be sure you read all the information about your four-wheel-drive vehicle in this manual. Is there enough fuel? Is the spare tire fully inflated? Are the fluid levels up where they should be? What are the local laws that apply to off-roading where you will be driving? If you do not know, you should check with law enforcement people in the area. Will you be on someone's private land? If so, be sure to get the necessary permission. Removable Side Steps Your vehicle may be equipped with removable side steps. Remove the steps prior to off roading to give your vehicle more ground clearance and to prevent damage to the vehicle from the side steps dragging and/or catching on obstacles. Notice: Do not drive off road with the side steps attached to your vehicle. You can damage the side steps and/or your vehicle's frame if they get caught or drag against an obstacle. This damage would not be covered by your vehicle's warranty. Always remove the side steps prior to any off road driving. Before You Go Off-Roading There are some things to do before you go out. For example, be sure to have all necessary maintenance and service work done. Check to make sure all underbody shields are properly attached. Make sure any equipment you may need (first aid kit, cell phone, flashlight, etc.) is securely stored in the vehicle. 4-16

Off-Road Driving

This off-road guide is meant to provide advice for when

you drive your vehicle off paved roads. Also, see

Braking on page 4-6

Off-road driving can be great fun. But it does have

some definite hazards. The greatest of these is

the terrain itself.

“Off-roading” means you have left the great North

American road system behind. Traffic lanes are not

marked. Curves are not banked. There are no

road signs. Surfaces can be slippery, rough, uphill or

downhill. In short, you have gone right back to nature.

Off-road driving involves some new skills. And that is

why it is very important that you read this guide. You will

find many driving tips and suggestions. These will help

make your off-road driving safer and more enjoyable.

Before You Go Off-Roading

There are some things to do before you go out. For

example, be sure to have all necessary maintenance

and service work done. Check to make sure all

underbody shields are properly attached. Make sure any

equipment you may need (first aid kit, cell phone,

flashlight, etc.) is securely stored in the vehicle.

Be sure you read all the information about your

four-wheel-drive vehicle in this manual. Is there enough

fuel? Is the spare tire fully inflated? Are the fluid

levels up where they should be? What are the local

laws that apply to off-roading where you will be driving?

If you do not know, you should check with law

enforcement people in the area. Will you be on

someone’s private land? If so, be sure to get the

necessary permission.

Removable Side Steps

Your vehicle may be equipped with removable

side steps.

Remove the steps prior to off roading to give your

vehicle more ground clearance and to prevent damage

to the vehicle from the side steps dragging and/or

catching on obstacles.

Notice:

Do not drive off road with the side steps

attached to your vehicle. You can damage the side

steps and/or your vehicle’s frame if they get caught

or drag against an obstacle. This damage would not

be covered by your vehicle’s warranty. Always

remove the side steps prior to any off road driving.
