close to the window. If the airflow is shut
off using the sliding knobs, warm air will be
directed to the other instrument panel
vents. This is normal operation.
Operation Tips
.Clear away any ice, snow, or leaves from
air inlets at the base of the windshield
that could block the flow of air into the
vehicle.
.Clear snow off the hood to improve
visibility and help decrease moisture
drawn into the vehicle.
.Keep the path under the front seats clear
of objects to help circulate the air inside
of the vehicle more effectively.
.Hood deflectors can adversely affect the
performance of the system. Check with
your dealer before adding equipment to
the outside of the vehicle.
Maintenance
Passenger Compartment Air Filter
The passenger compartment air filter
reduces dust, pollen, and other airborne
irritants from outside air that is pulled into
the vehicle. Replace the filter periodically.
SeeMaintenance Schedule 0328. Using the climate control system without an
air filter installed is not recommended.
Water or other debris could enter the
system and result in leaks or noises. Always
install a new filter when removing the old
filter.
For more information on filter replacement,
see your dealer.
Service
All vehicles have a label underhood that
identifies the refrigerant used in the vehicle.
The refrigerant system should only be
serviced by trained and certified technicians.
The air conditioning evaporator should never
be repaired or replaced by one from a
salvage vehicle. It should only be replaced
by a new evaporator to ensure proper and
safe operation.
During service, all refrigerants should be
reclaimed with proper equipment. Venting
refrigerants directly to the atmosphere is
harmful to the environment and may also
create unsafe conditions based on
inhalation, combustion, frostbite, or other
health-based concerns.
The air conditioning system requires periodic
maintenance. See
Maintenance Schedule
0 328.

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:
.Set the climate controls to the desired
temperature after the engine is started,
or turn them off when not required.
.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.
.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.
Distracted Driving
Distraction comes in many forms and can
take your focus from the task of driving.
Exercise good judgment and do not let other
activities divert your attention away from
the road. Many local governments have
enacted laws regarding driver distraction.
Become familiar with the local laws in
your area.
To avoid distracted driving, keep your eyes
on the road, keep your hands on the
steering wheel, and focus your attention on
driving.
.Do not use a phone in demanding driving
situations. Use a hands-free method to
place or receive necessary phone calls.
.Watch the road. Do not read, take notes,
or look up information on phones or
other electronic devices.
.Designate a front seat passenger to
handle potential distractions.
.Become familiar with vehicle features
before driving, such as programming
favorite radio stations and adjusting
climate control and seat settings. Program
all trip information into any navigation
device prior to driving.

applied. Once the power assist is used up, it
can take longer to stop and the brake pedal
will be harder to push.
Steering
Caution
To avoid damage to the steering system,
do not drive over curbs, parking barriers,
or similar objects at speeds greater than
3 km/h (1 mph). Use care when driving
over other objects such as lane dividers
and speed bumps. Damage caused by
misuse of the vehicle is not covered by
the vehicle warranty.
Electric Power Steering
The vehicle is equipped with an electric
power steering system, which reduces the
amount of effort needed to steer the
vehicle. It does not have power steering
fluid. Regular maintenance is not required.
If the vehicle experiences a system
malfunction and loses power steering,
greater steering effort may be required.
Power steering assist also may be reduced if
you turn the steering wheel as far as it can
turn and hold it there with force for an
extended period of time.
See your dealer if there is a problem.
Curve Tips
.Take curves at a reasonable speed.
.Reduce speed before entering a curve.
.Maintain a reasonable steady speed
through the curve.
.Wait until the vehicle is out of the curve
before accelerating gently into the
straightaway.
Steering in Emergencies
.There are some situations when steering
around a problem may be more effective
than braking.
.Holding both sides of the steering wheel
allows you to turn 180 degrees without
removing a hand.
.The Antilock Brake System (ABS) allows
steering while braking.
Off-Road Recovery
The vehicle's right wheels can drop off the
edge of a road onto the shoulder while
driving. Follow these tips:1. Ease off the accelerator and then, if there is nothing in the way, steer the
vehicle so that it straddles the edge of
the pavement.

154 Driving and Operating
Before Driving Your Vehicle Off-Road
Have all necessary maintenance and service
work completed.
Fuel the vehicle, fill fluid levels, and check
inflation pressure in all tires, including the
spare, if equipped.
Read all the information about
four-wheel-drive vehicles in this manual.
Remove any underbody air deflector,
if equipped. Re-attach the air deflector after
off-road driving.
Know the local laws that apply to off-road
driving.
To gain more ground clearance if needed, it
may be necessary to remove the front fascia
lower air dam, if equipped. However, driving
without the air dam reduces fuel economy.
Caution
Operating the vehicle for extended
periods without the front fascia lower air
dam installed can cause improper airflow
to the engine. Reattach the front fascia
air dam after off-road driving.
Loading the Vehicle for Off-Road Driving
{Warning
.Unsecured cargo on the load floor can
be tossed about when driving over
rough terrain. You or your passengers
can be struck by flying objects. Secure
the cargo properly.
.Keep cargo in the cargo area as far
forward and as low as possible. The
heaviest things should be on the floor,
forward of the rear axle.
.Heavy loads on the roof raise the
vehicle's center of gravity, making it
more likely to roll over. You can be
seriously or fatally injured if the
vehicle rolls over. Put heavy loads
inside the cargo area, not on the roof.
For more information about loading the
vehicle, see Vehicle Load Limits 0162 and
Tires 0284.
Environmental Concerns
Always use established trails, roads, and
areas that are reserved for public off-road
recreational driving. Obey all posted
regulations. Do not damage shrubs, flowers, trees,
or grasses or disturb wildlife.
Do not park over things that burn. See
Parking over Things That Burn
0173.
Driving on Hills
Driving safely on hills requires good
judgment and an understanding of the
vehicle’s capabilities.
{Warning
Many hills are simply too steep for any
vehicle. Driving up hills can cause the
vehicle to stall. Driving down hills can
cause loss of control. Driving across hills
can cause a rollover. You could be injured
or killed. Do not drive on steep hills.
Before driving on a hill, assess the
steepness, traction, and obstructions. If the
terrain ahead cannot be seen, get out of the
vehicle and walk the hill before driving
further.
When driving on hills:
.Maintain a slow speed and keep a firm
grip on the steering wheel.
.Use headlamps even during the day to
make the vehicle more visible.

Warning (Continued)
shallow water, it can still wash away the
ground from under your tires. Traction
could be lost, and the vehicle could roll
over. Do not drive through rushing water.
Caution
Do not drive through standing water if it
is deep enough to cover the wheel hubs,
axles, or exhaust pipe. Deep water can
damage the axle and other vehicle parts.
If the standing water is not too deep, drive
through it slowly. At faster speeds, water
can get into the engine and cause it to stall.
Stalling can occur if the exhaust pipe is
under water.
Do not turn off the ignition when driving
through water. If the exhaust pipe is under
water, the engine will not start.
Always drive in the direction of waves.
Avoid oncoming vehicles as they will
increase the water depth hitting your
vehicle. Be aware of submerged obstacles as they
can damage your vehicle or cause loss of
control.
Never open the vehicle doors while in the
water.
When going through water, the brakes get
wet and it may take longer to stop. After
exiting the water, repeatedly and gently
apply the brakes to dry them off and
restore effectiveness. See
Driving on Wet
Roads 0159.
After Driving Your Vehicle Off-Road
Be sure to switch out of Off-Road Mode or
Terrain Mode on your Driver Mode Control
to return to normal driving. See Driver Mode
Control 0187.
Remove any brush or debris that has
collected on the underbody or chassis,
or under the hood. Clean the lens of the
underbody camera. These accumulations can
be a fire hazard.
After operation in mud or sand, have the
brake linings cleaned and checked. These
substances can cause glazing and uneven
braking. Check the body structure, driveline, steering,
suspension, wheels, tires, and exhaust
system for damage, and check the fuel lines
and cooling system for any leakage.
{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.
The extreme conditions of off-road driving
require more frequent maintenance service.
See "Severe Conditions Requiring More
Frequent Maintenance" and "Additional
Required Services —Severe Service" on
Maintenance Schedule 0328.

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, thisfeature 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 0328.
Locking Rear Axle
If equipped, the locking rear axle can give
the vehicle additional traction from the rear
wheels when traveling in off-road situations
such as mud, snow, steep hills, and uneven
terrain.
