6. To tighten the belt, push downon the child restraint, pull the
shoulder portion of the belt to
tighten the lap portion of the belt,
and feed the shoulder belt back
into the retractor. When installing
a forward-facing child restraint, it
may be helpful to use your knee
to push down on the child
restraint as you tighten the belt.
Try to pull the belt out of the
retractor to make sure the
retractor is locked. If the
retractor is not locked, repeat
Steps 5 and 6. 7. Before placing a child in the
child restraint, make sure it is
securely held in place. To check,
grasp the child restraint at the
safety belt path and attempt to
move it side-to-side and
back-and-forth. When the child
restraint is properly installed,
there should be no more than
2.5 cm (1 in) of movement.
If the vehicle is equipped with the
passenger sensing system, and
when the passenger sensing system
has turned off the front outboard
passenger frontal airbag, the off
indicator in the passenger airbag
status indicator should light and stay
lit when you start the vehicle. See
Passenger Airbag Status Indicator
on page 5-17. If a child restraint has been installed
and the on indicator is lit, see
“If the
On Indicator is Lit for a Child
Restraint” underPassenger Sensing
System on page 3-33 for more
information.
To remove the child restraint,
unbuckle the vehicle safety belt and
let it return to the stowed position.

Driving Information
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, always
keep your eyes on the road, hands
on the wheel, and mind on the drive.
.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.
.Wait until the vehicle is parked
to retrieve items that have fallen
to the floor.
.Stop or park the vehicle to tend
to children.
.Keep pets in an appropriate
carrier or restraint.
.Avoid stressful conversations
while driving, whether with a
passenger or on a cell phone.

Using heavier suspension
components to get added
durability might not change your
weight ratings. Ask your dealer
to help you load your vehicle the
right way.
If you put things inside your
vehicle—like suitcases, tools,
packages, or anything
else —they go as fast as the
vehicle goes. If you have to stop
or turn quickly, or if there is a
crash, they will keep going.
{Warning
Things you put inside the
vehicle can strike and injure
people in a sudden stop or
turn, or in a crash.
.Put things in the cargo
area of the vehicle. Try to
spread the weight evenly.
(Continued)
Warning (Continued)
.Never stack heavier
things, like suitcases,
inside the vehicle so that
some of them are above
the tops of the seats.
.Do not leave an
unsecured child restraint
in the vehicle.
.When you carry something
inside the vehicle, secure
it whenever you can.
.Do not leave a seat folded
down unless you need to.
There is also important loading
information for off-road driving in
this manual. See “Loading Your
Vehicle for Off-Road Driving”
under Off-Road Driving on
page 9-5.
Starting and
Operating
New Vehicle Break-In
Notice: The vehicle does not
need an elaborate break-in. But it

88 km/h (55 mph) or less for
the first 805 km (500 miles).
.Do not drive at any one
constant speed, fast or slow,
for the first 805 km
(500 miles). Do not make
full-throttle starts. Avoid
downshifting to brake or
slow the vehicle.
