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.

{ WarningTaking your eyes off the road too
long or too often could cause a
crash resulting in injury or death.
Focus your attention on driving.
Refer to the infotainment manual for
more information on using that
system and the navigation system,
if equipped, including pairing and
using a cell phone.
Defensive Driving Defensive driving means “ always
expect the unexpected. ” The first
step in driving defensively is to wear
the seat belt. See Seat Belts 0 54 .
.
Assume that other road users
(pedestrians, bicyclists, and
other drivers) are going to be
careless and make mistakes.
Anticipate what they might do
and be ready. .
Allow enough following distance
between you and the driver in
front of you.
.
Focus on the task of driving.
Drunk Driving Death and injury associated with
drinking and driving is a global
tragedy.
{ WarningDrinking and then driving is very
dangerous. Your reflexes,
perceptions, attentiveness, and
judgment can be affected by even
a small amount of alcohol. You
can have a serious — or even
fatal — collision if you drive after
drinking.
Do not drink and drive or ride with
a driver who has been drinking.

Driving and Operating 169Defensive drivers avoid most skids
by taking reasonable care suited to
existing conditions, and by not
overdriving those conditions. But
skids are always possible.
If the vehicle starts to slide, follow
these suggestions:
.
Ease your foot off the
accelerator pedal and steer the
way you want the vehicle to go.
The vehicle may straighten out.
Be ready for a second skid if it
occurs.
.
Slow down and adjust your
driving according to weather
conditions. Stopping distance
can be longer and vehicle
control can be affected when
traction is reduced by water,
snow, ice, gravel, or other
material on the road. Learn to
recognize warning clues — such
as enough water, ice, or packed
snow on the road to make a
mirrored surface — and slow
down when you have any doubt. .
Try to avoid sudden steering,
acceleration, or braking,
including reducing vehicle speed
by shifting to a lower gear. Any
sudden changes could cause
the tires to slide.
Remember: Antilock brakes help
avoid only the braking skid.
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 warranty 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. { WarningWhen 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.

170 Driving and Operating 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.
CautionOperating 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.
(Continued) Warning (Continued) .
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
0 177 .
Environmental Concerns
.
Always use established trails,
roads, and areas that have been
set aside for public off-road
recreational driving and 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 0 189 .
Driving on Hills Driving safely on hills requires good
judgment and an understanding of
what the vehicle can and cannot do.
{ WarningMany 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.
