suspension, wheels, tires, and other vehicle
systems for damage, or have these
inspections done by your dealer.
{Warning
Lifting a vehicle and getting under it to
do maintenance or repairs is dangerous
without the appropriate safety equipment
and training. If a jack is provided with
the vehicle, it is designed only for
changing a flat tire. If it is used for
anything else, you or others could be
badly injured or killed if the vehicle slips
off the jack. If a jack is provided with the
vehicle, only use it for changing a
flat tire.
Driving on Wet Roads
Rain and wet roads can reduce vehicle
traction and affect your ability to stop and
accelerate. Always drive slower in these
types of driving conditions and avoid driving
through large puddles and deep-standing or
flowing water.

Maximum vehicle speed may be limited if
the four-wheel steering system becomes
inoperable.
When towing a trailer the four-wheel
steering provides enhanced stability allowing
the trailer to follow the path of the tow
vehicle more closely, especially during lane
changes. SeeGeneral Towing Information
0 293 for more information on towing a
trailer.
Four-Wheel Steering Behavior at 0 MPH
The rear wheels may not steer to full travel
when the vehicle is stationary. Additional
travel may be achieved once the vehicle
begins to move.
Care should be taken to ensure the vehicle
path is clear of obstacles if the rear tires
steer once the vehicle is moving.
Limited-Slip Differential
If equipped, the limited-slip differential can
give more traction on snow, mud, ice, sand,
or gravel. It works like a standard axle most
of the time, but when traction is low, this
feature allows the drive wheel with the
most traction to move the vehicle. For
vehicles with the limited-slip differential, driven under severe conditions, the rear axle
fluid should be changed. See
Maintenance
Schedule 0389.
Air Suspension
If equipped, the Air Suspension feature
provides full time load leveling capability
along with the benefit of adjusting ride
height for increased convenience and
capability.
{Warning
To help avoid personal injury or death,
make sure the area underneath the
vehicle and inside the wheel wells is clear
when lowering the vehicle.
{Warning
To help avoid personal injury or death,
always select the lowest ride height for
the current driving conditions. Higher ride
heights raise the vehicle's center of
gravity, increasing the chance of a
rollover during extreme maneuvers.
{Warning
Heavy loads on the roof rack will make
the vehicle's center of gravity higher,
increasing the possibility of a rollover. To
avoid losing control of the vehicle, always
select the normal height setting and
avoid high speeds, sudden starts, sharp
turns, sudden braking, or abrupt
maneuvers when carrying cargo on the
roof rack.
Changing Ride Height
Press either “Up”or“Down” Ride Height
button to open the Ride Height menu. Select
the desired ride height from the following

before and during each trip. Check periodically that all nuts and bolts on
the trailer hitch are tight.
Trailer Towing
Caution
Towing a trailer improperly can damage
the vehicle and result in costly repairs
not covered by the vehicle warranty. To
tow a trailer correctly, follow the
directions in this section and see your
dealer for important information about
towing a trailer with the vehicle.
Trailering is different than just driving the
vehicle by itself. Trailering means changes in
handling, acceleration, braking, and
durability. Successful, safe trailering takes
correct equipment, and it has to be used
properly.
The following information has many
time-tested, important trailering tips and
safety rules. Many of these are important
for your safety and that of your passengers.
Read this section carefully before pulling a
trailer.
Trailer Weight
{Warning
Never exceed the towing capacity for
your vehicle.
Safe trailering requires monitoring the
weight, speed, altitude, road grades, outside
temperature, and how frequently the vehicle
is used to tow a trailer.
Trailer Weight Ratings
When towing a trailer, the combined weight
of the vehicle, vehicle contents, trailer, and
trailer contents must be below all of the
maximum weight ratings for the vehicle,
including:
.Gross Combined Weight Rating (GCWR)
.Gross Vehicle Weight Rating (GVWR)
.Maximum Trailer Weight Rating
.Maximum Trailer Tongue Weight Rating
.Gross Axle Weight Rating-Rear (GAWR-RR)
See “Weight-Distributing Hitch and
Adjustment” underTowing Equipment 0301
to determine if equalizer bars are required
to obtain the maximum trailer weight
rating.
