filter should be replaced as part of
routine scheduled maintenance. See
Maintenance Schedule0395.
See your dealer regarding replacement
of the filter.
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 0395.

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.
.On AWD vehicles, use Tour Mode
when conditions permit.
.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.

(60 mph) travels 20 m (66 ft), which
could be a lot of distance in an
emergency.
Helpful braking tips to keep in mind
include:
.Keep enough distance between you
and the vehicle in front of you.
.Avoid needless heavy braking.
.Keep pace with traffic.
If the engine ever stops while the
vehicle is being driven, brake normally
but do not pump the brakes. Doing so
could make the pedal harder to push
down. If the engine stops, there will
be some power brake assist but it will
be used when the brake is applied.
Once the power assist is used up, it
can take longer to stop and the brake
pedal will be harder to push.
Steering
Electric Power Steering
Caution
To avoid damage to the steering
system, do not drive over curbs,
parking barriers, or similar objects (Continued)
Caution (Continued)
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.
The vehicle has electric power
steering. It does not have power
steering fluid. Regular maintenance is
not required.
If power steering assist is lost due to a
system malfunction, the vehicle can
be steered, but may require increased
effort. If the steering assist is used for an
extended period of time while the
vehicle is not moving, power assist
may be reduced.
If the steering wheel is turned until it
reaches the end of its travel and is
held against that position for an
extended period of time, power
steering assist may be reduced.
Normal use of the power steering
assist should return when the system
cools down.
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.

220 DRIVING AND OPERATING
Off-Road Driving
All-Wheel Drive vehicles can be used
for off-road driving. Vehicles without
All-Wheel Drive and vehicles not
equipped with All Terrain (AT) or
On-Off Road (OOR) tires must not be
driven off-road except on a level, solid
surface. To contact the tire
manufacturer for more information
about the original equipment tires, see
the Limited Warranty and Owner
Assistance Information manual.
Controlling the vehicle is the key to
successful off-road driving. One of the
best ways to control the vehicle is to
control the speed.
{Warning
When driving off-road, bouncing
and quick changes in direction can
easily throw you out of position.
This could cause you to lose control
and crash. You and your passengers
should always wear seat belts.
Before Driving 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
All-Wheel Drive vehicles in this
manual.
.Make sure all underbody shields,
if equipped, are properly attached.
.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.
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 airf low 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
0 226.

Parking on Hills
{Warning
To prevent serious injury or death,
always park your vehicle and trailer
on a level surface when possible.
When parking your vehicle and your
trailer on a hill: 1. Press the brake pedal, but do not shift into P (Park) yet. Turn the
wheels into the curb if facing
downhill or into traffic if facing
uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, gradually release the brake
pedal to allow the chocks to absorb
the load of the trailer.
4. Reapply the brake pedal. Then apply the parking brake and shift
into P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal:
.Start the engine.
.Shift into a gear.
.Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer
Towing
The vehicle needs service more often
when used to tow trailers. See
Maintenance Schedule 0395. It is
especially important to check the
transmission for fluid leaks, engine
oil, axle lubricant, belts, cooling
system, and brake system before and
during each trip.
Check periodically that all nuts and
bolts on the trailer hitch are tight.
Engine Cooling When Trailer
Towing
The cooling system may temporarily
overheat during severe operating
conditions. See Engine Overheating
0 334.
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.

causes, including an improperly or
overloaded trailer, unrestrained
cargo, improper trailer hitch
configuration, or improperly
inflated or incorrect vehicle or
trailer tires. SeeTowing Equipment
0 312 for trailer ratings and hitch
setup recommendations.
Trailer Tires
Special Trailer (ST) tires differ from
vehicle tires. Trailer tires are designed
with stiff sidewalls to help prevent
sway and to support heavy loads.
These features can make it difficult to
determine if the trailer tire pressures
are low only based on a visual
inspection.
Always check all trailer tire pressures
before each trip when the tires are
cool. Low trailer tire pressure is a
leading cause of trailer tire blowouts.
Trailer tires deteriorate over time. The
trailer tire sidewall will show the week
and year the tire was manufactured. Many trailer tire manufacturers
recommend replacing tires more than
six years old.
Overloading is another leading cause
of trailer tire blowouts. Never load the
trailer with more weight than the tires
are designed to support. The load
rating is on the trailer tire sidewall.
Always know the maximum speed
rating for the trailer tires before
driving. This may be significantly
lower than the vehicle tire speed
rating. The speed rating may be on
the trailer tire sidewall. If the speed
rating is not shown, the default trailer
tire speed rating is 105 km/h (65 mph).
