Introduction

Pull the release lever to release the
brake. Driving with the parking
brake on will cause the brakes to
wear out quickly and reduce fuel
economy.
STEERING
Your vehicle is equipped with power steering. Power steering uses energy
from the engine to help steer the vehicle.
To prevent damage to the power steering pump:
•Never hold the steering wheel to the extreme right or the extreme left
for more than a few seconds when the engine is running.
•Do not operate the vehicle with a low power steering pump fluid level
(below the MIN mark on the reservoir).
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, the condition could be caused by any of
the following:
•underinflated tire(s) on any wheel(s)
•uneven vehicle loading
•high crown in center of road
•high crosswinds
•wheels out of alignment
•loose or worn suspension components

Speed sensitive steering
The steering in your vehicle is speed sensitive. At high speeds, steering
assist will decrease to improve steering feel.
If the amount of effort required to steer your vehicle changes while
driving at a constant vehicle speed, have the power steering system
checked by your dealer or a qualified service technician.
AIR SUSPENSION SYSTEM (IF EQUIPPED)
The air suspension system is designed to improve ride, handling and
general vehicle performance for static, on and off-road driving conditions.
•The load leveling feature of the air suspension automatically keeps the
vehicle at a constant level if a load is added or removed from the
vehicle.
•The height adjustment feature automatically controls the vehicle
height over a range of approximately 5 cm (2 inches) based on vehicle
speed, ignition position and selection of two or four-wheel drive
modes.
•The air suspension automatically puts the vehicle at its lowest height
when ignition is OFF to provide easy entry and exit. When ever a door
is opened (including the liftgate) the system memorizes and maintains
the height of the vehicle until all doors are closed or until vehicle
exceeds 16km/h (10mph).
•The air suspension system raises the vehicle to its normal ride
position when the ignition is turned on, all doors are closed and the
transmission is shifted into gear.
•In 4WD Low the air suspension system will not move to its lowest
height. In 4WD Low, the air suspension system raises the vehicle
above the normal ride height at speeds below 40 km/h (25 mph) to
improve ground clearance. In 4WD Low, do not exceed 56 km/h
(35 mph).
•When the vehicle is in motion, the air suspension system will adjust
the vehicle’s height according to ground clearance and speed to
maximize ride comfort.
•It is normal to occasionally hear a buzz or clicking from the vehicle’s
air suspension system when the ignition is turned off. The system
stays energized for 40 minutes after the ignition is turned off to
compensate for any load changes made after the vehicle is parked.

Passenger compartment fuse panel
The fuse panel is located below and to the left of the steering wheel by
the brake pedal. Remove the panel cover to access the fuses.
To remove a fuse use the fuse puller tool provided on the fuse panel
cover.

CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.

What you should know about fail-safe cooling
If the engine coolant supply is depleted, this feature allows the vehicle to
be driven temporarily before incremental component damage is incurred.
The“fail-safe”distance depends on ambient temperatures, vehicle load
and terrain.
How fail-safe cooling works
If the engine begins to overheat:
•the engine coolant temperature
gauge will move to the red (hot)
area.
•the
and thesymbol
will illuminate.
•theService Engine Soon
indicator light will illuminate.
If the engine reaches a preset over-temperature condition, the engine
will automatically switch to alternating cylinder operation. Each disabled
cylinder acts as an air pump and cools the engine.
When this occurs the vehicle will still operate. However:
•the engine power will be limited.
•the air conditioning system will be disabled.
Continued operation will increase the engine temperature:
•the engine will completely shut down.
•steering and braking effort will increase.
Once the engine temperature cools, the engine can be re-started. Take
your vehicle to a service facility as soon as possible to minimize engine
damage.
When fail-safe mode is activated
You have limited engine power when in the fail-safe mode, so drive the
vehicle with caution. The vehicle will not be able to maintain high speed
operation and the engine will run rough. Remember that the engine is
capable of completely shutting down automatically to prevent engine
damage, therefore:
1. Pull off the road as soon as safely possible and turn off the engine.
2. Arrange for the vehicle to be taken to a service facility.
