Driving Information
Driving for Better Fuel
Economy
Driving habits can affect fuel
mileage. Here are some driving tips
to get the best fuel economy
possible.
.Avoid fast starts and accelerate
smoothly.
.Brake gradually and avoid
abrupt stops.
.Avoid idling the engine for long
periods of time.
.When road and weather
conditions are appropriate, use
cruise control, if equipped.
.Always follow posted speed
limits or drive more slowly when
conditions require.
.Keep vehicle tires properly
inflated.
.Combine several trips into a
single trip.
.Replace the vehicle's tires with
the same TPC Spec number
molded into the tire's sidewall
near the size.
.Follow recommended scheduled
maintenance.

8-8 Driving and Operating
Many of the vehicle design features
that help make the vehicle more
responsive on paved roads during
poor weather conditions also help
make it better suited for off‐road use
than conventional passenger
vehicles. The vehicle does not have
features usually thought to be
necessary for extended or severe
off‐road use such as special
underbody shielding and transfer
case low gear range.
The airbag system is designed to
work properly under a wide range of
conditions, including off‐road usage.
Always wear your safety belt and
observe safe driving speeds,
especially on rough terrain.
Drinking and driving can be very
dangerous on any road and this is
certainly true for off-road driving.
At the very time you need special
alertness and driving skills, your
reflexes, perceptions, and judgmentcan be affected by even a small
amount of alcohol. You could have a
serious
—or even fatal —accident
if you drink and drive or ride with a
driver who has been drinking.
Off-roading can be great fun but has
some definite hazards. The greatest
of these is the terrain itself. When
off-road driving, traffic lanes are not
marked, curves are not banked, and
there are no road signs. Surfaces
can be slippery, rough, uphill,
or downhill.
Avoid sharp turns and abrupt
maneuvers. Failure to operate the
vehicle correctly off‐road could
result in loss of vehicle control or
vehicle rollover.
Off-roading involves some new
skills. That is why it is very
important that you read these
driving tips and suggestions to help
make off-road driving safer and
more enjoyable.Before You Go Off-Roading
.Have all necessary maintenance
and service work done.
.Make sure there is enough fuel,
that fluid levels are where they
should be, and that the spare
tire is fully inflated.
.Be sure to read all the
information about all-wheel-drive
vehicles in this manual.
.Make sure all underbody
shields, if the vehicle has them,
are properly attached.
.Know the local laws that apply to
off-roading where you will be
driving or check with law
enforcement people in the area.
.Be sure to get the necessary
permission if you will be on
private land.

Driving and Operating 8-19
.Keep your eyes moving—scan
the road ahead and to the sides.
.Check the rearview mirror and
vehicle instruments often.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. Tips for
driving in these conditions include:
.Keep the vehicle serviced and in
good shape.
.Check all fluid levels and brakes,
tires, cooling system, and
transmission.
.Going down steep or long hills,
shift to a lower gear.
{WARNING
If you do not shift down, the
brakes could get so hot that they
would not work well. You would
then have poor braking or even
none going down a hill. You could
crash. Shift down to let the engine
assist the brakes on a steep
downhill slope.
{WARNING
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. The brakes will have
to do all the work of slowing down
and they could get so hot that
(Continued)
WARNING (Continued)
they would not work well. You
would then have poor braking or
even none going down a hill. You
could crash. Always have the
engine running and the vehicle in
gear when going downhill.
.Stay in your own lane. Do not
swing wide or cut across the
center of the road. Drive at
speeds that let you stay in your
own lane.
.Top of hills: Be alert—
something could be in your lane
(stalled car, accident).
.Pay attention to special road
signs (falling rocks area, winding
roads, long grades, passing or
no-passing zones) and take
appropriate action.

Driving and Operating 8-23
{WARNING
Do not load the vehicle any
heavier than the Gross
Vehicle Weight Rating
(GVWR), or either the
maximum front or rear Gross
Axle Weight Rating (GAWR).
If you do, parts on the vehicle
can break, and it can change
the way the vehicle handles.
These could cause you to lose
control and crash. Also,
overloading can shorten the
life of the vehicle. Tire and Loading Information
Label
Label Example
A vehicle specific Tire and
Loading Information label is
attached to the vehicle's center
pillar (B-pillar). With the driver's
door open, you will find the label
attached near the door lock
post. The Tire and Loading
Information label shows the
number of occupant seating positions (A), and the maximum
vehicle capacity weight (B) in
kilograms and pounds.
The Tire and Loading
Information label also shows
the tire size of the original
equipment tires (C) and the
recommended cold tire inflation
pressures (D). For more
information on tires and inflation
see
Tires
on page 9‑45and Tire
Pressure
on page 9‑52.
There is also important loading
information on the Certification
label. It tells you the Gross
Vehicle Weight Rating (GVWR)
and the Gross Axle Weight
Rating (GAWR) for the front and
rear axle. See “Certification
Label” later in this section.

Driving and Operating 8-65
Total Weight on the
Vehicle's Tires
Inflate the vehicle's tires to the
upper limit for cold tires. These
numbers can be found on the
Certification label or seeVehicle
Load Limits
on page 8‑22for more
information. Do not go over the
GVW limit for the vehicle, or the
GAWR, including the weight of the
trailer tongue. If using a weight
distributing hitch, do not go over the
rear axle limit before applying the
weight distribution spring bars.
Towing Equipment
Hitches
Use the correct hitch equipment.
See your dealer/retailer or a hitch
dealer for assistance.
.The rear bumper on the vehicle
is not intended for hitches. Do
not attach rental hitches or other
bumper-type hitches to it. Use
only a frame-mounted hitch that
does not attach to the bumper.
.Will any holes be made in the
body of the vehicle when the
trailer hitch is installed? If there
are, seal the holes when the
hitch is removed. If the holes are
not sealed, dirt, water, and
deadly carbon monoxide (CO)
from the exhaust can get into the
vehicle. See Engine Exhaust
on
page 8‑34.
Safety Chains
Always attach chains between the
vehicle and the trailer. Cross the
safety chains under the tongue of
the trailer to help prevent the tongue
from contacting the road if it
becomes separated from the hitch.
Leave enough slack so the rig can
turn. Never allow safety chains to
drag on the ground.
Trailer Brakes
Does the trailer have its own
brakes? Be sure to read and follow
the instructions for the trailer brakes
so they are installed, adjusted and
maintained properly.
Because the vehicle has antilock
brakes, do not tap into the vehicle's
brake system. If this is done, both
brake systems will not work well,
or at all.
