The manufacturer’s instructions that
come with the booster seat, state the
weight and height limitations for that
booster. Use a booster seat with a
lap-shoulder belt until the child
passes the below t test:
Sit all the way back on the seat.
Do the knees bend at the seat
edge? If yes, continue. If no,
return to the booster seat.
Buckle the lap-shoulder belt.
Does the shoulder belt rest on the
shoulder? If yes, continue. If no,
try using the rear safety belt
comfort guide. See “Rear Safety
Belt Comfort Guides” under
Lap-Shoulder Belt on page 1-20
for more information. If the
shoulder belt still does not rest on
the shoulder, then return to the
booster seat.
Does the lap belt t low and snug
on the hips, touching the thighs?
If yes, continue. If no, return to the
booster seat.
Can proper safety belt t be
maintained for the length of the
trip? If yes, continue. If no, return
to the booster seat.
Q:What is the proper way to
wear safety belts?
A:An older child should wear a
lap-shoulder belt and get the
additional restraint a shoulder belt
can provide. The shoulder belt
should not cross the face or neck.
The lap belt should t snugly
below the hips, just touching the
top of the thighs. This applies belt
force to the child’s pelvic bones in
a crash. It should never be worn
over the abdomen, which could
cause severe or even fatal
internal injuries in a crash.Also see “Rear Safety Belt Comfort
Guides” underLap-Shoulder Belt
on page 1-20.
According to accident statistics,
children and infants are safer when
properly restrained in a child
restraint system or infant restraint
system secured in a rear seating
position.
In a crash, children who are not
buckled up can strike other people
who are buckled up, or can be
thrown out of the vehicle. Older
children need to use safety belts
properly.

Engine Coolant Heater
The engine coolant heater can
provide easier starting and better
fuel economy during engine
warm-up in cold weather conditions
at or below 0°F (−18°C). Vehicles
with an engine coolant heater should
be plugged in at least four hours
before starting. An internal
thermostat in the plug-end of the
cord may exist which will prevent
engine coolant heater operation
at temperatures above 0°F (−18°C).
To Use the Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord. The cord is
located in the engine
compartment behind the
underhood fuse block on the
driver side of the vehicle.
3. Plug it into a normal, grounded
110-volt AC outlet.
{CAUTION
Plugging the cord into an
ungrounded outlet could cause an
electrical shock. Also, the wrong
kind of extension cord could
overheat and cause a re. You
could be seriously injured. Plug
the cord into a properly grounded
three-prong 110-volt AC outlet.
If the cord will not reach, use a
heavy-duty three-prong extension
cord rated for at least 15 amps.
4. Before starting the engine, be
sure to unplug and store the
cord to prevent damage.
The length of time the heater should
remain plugged in depends on
several factors. Ask a dealer/retailer
in the area where you will be
parking the vehicle for the best
advice on this.
Automatic Transmission
Operation
The automatic transmission has a
shift lever on the console.

Driving Across an Incline
An off-road trail will probably go
across the incline of a hill. To decide
whether to try to drive across the
incline, consider the following:
{CAUTION
Driving across an incline that is
too steep will make your vehicle
roll over. You could be seriously
injured or killed. If you have any
doubt about the steepness of the
incline, do not drive across it. Find
another route instead.
A hill that can be driven
straight up or down might be
too steep to drive across. When
going straight up or down a
hill, the length of the wheel
base — the distance from
the front wheels to the rear
wheels —reduces the likelihoodthe vehicle will tumble end over
end. But when driving across
an incline, the narrower
track width — the distance
between the left and right
wheels — might not prevent the
vehicle from tilting and rolling
over. Driving across an incline
puts more weight on the downhill
wheels which could cause a
downhill slide or a rollover.
Surface conditions can be a
problem. Loose gravel, muddy
spots, or even wet grass can
cause the tires to slip sideways,
downhill. If the vehicle slips
sideways, it can hit something
that will trip it — a rock, a rut,
etc. — and roll over.
Hidden obstacles can make the
steepness of the incline even
worse. If you drive across a rock
with the uphill wheels, or if the
downhill wheels drop into a rut or
depression, the vehicle can tilt
even more.
For these reasons, carefully
consider whether to try to drive
across an incline. Just because the
trail goes across the incline does
not mean you have to drive it.
The last vehicle to try it might have
rolled over.
If you feel the vehicle starting to
slide sideways, turn downhill. This
should help straighten out the
vehicle and prevent the side
slipping. The best way to prevent
this is to “walk the course” rst,
so you know what the surface is like
before driving it.
