6. Connect the red positive (+)
cable to the positive (+) terminal
of the dead battery.
Use a remote positive (+)
terminal if the vehicle has one.7. Do not let the other end
touch metal. Connect it to the
positive (+) terminal of the good
battery. Use a remote positive (+)
terminal if the vehicle has one.
8. Now connect the black
negative (−) cable to the
negative (−) terminal of the
good battery. Use a remote
negative (−) terminal if the
vehicle has one.
Do not let the other end touch
anything until the next step.
The other end of the negative (−)
cable does not go to the dead
battery. It goes to a heavy,
unpainted metal engine part, or to
a remote negative (−) terminal on
the vehicle with the dead battery.9. Connect the other end of the
negative (−) cable at least
18 inches (45 cm) away from
the dead battery, but not near
engine parts that move.
The electrical connection is just
as good there, and the chance
of sparks getting back to the
battery is much less.
Your vehicle has a remote
negative (−) terminal for this
purpose.

10. Now start the vehicle with the
good battery and run the
engine for a while.
11. Try to start the vehicle that had
the dead battery. If it will not
start after a few tries, it probably
needs service.
Notice:If the jumper cables
are connected or removed in the
wrong order, electrical shorting
may occur and damage the
vehicle. The repairs would not be
covered by your warranty. Always
connect and remove the jumper
cables in the correct order,
making sure that the cables do not
touch each other or other metal.A. Heavy, Unpainted Metal Engine

from both vehicles, do the following:
1. Disconnect the black negative (−)
cable from the vehicle that had
the dead battery.
2. Disconnect the black negative (−)
cable from the vehicle with the
good battery.
3. Disconnect the red positive (+)
cable from the vehicle with the
good battery.
4. Disconnect the red positive (+)

All-Wheel Drive
It is recommended that the all-wheel
drive lubricants be checked and
lled by the dealer/retailer.
When to Check Lubricant
Refer to the Maintenance Schedule
to determine how often to check
the lubricant. SeeScheduled
Maintenance on page 6-3.
Headlamp Aiming
Headlamp aim has been preset at
the factory and should need no
further adjustment.
However, if your vehicle is damaged
in a crash, the headlamp aim may
be affected. Aim adjustment to
the low-beam headlamps may be
necessary if oncoming drivers ash
their high-beam headlamps at
you (for vertical aim).
If the headlamps need to be
re-aimed, it is recommended that
you take the vehicle to your
dealer/retailer for service.
Bulb Replacement
For the proper type of replacement
bulbs, seeReplacement Bulbs
on page 5-34.
For any bulb changing procedure
not listed in this section, contact
your dealer/retailer.
Halogen Bulbs
{CAUTION
Halogen bulbs have pressurized
gas inside and can burst if you
drop or scratch the bulb. You or
others could be injured. Be sure
to read and follow the instructions
on the bulb package.

3. Install the new wiper blade and
make sure the wiper blade
locks into place.
For the proper size and type see
Maintenance Replacement Parts on
page 6-14.
Backglass Wiper Blade
To replace the backglass wiper
blade:
1. Pull the wiper blade assembly
away from the backglass.
The backglass wiper blade will
not lock in a vertical position
so care should be used when
pulling it away from the vehicle.
2. Rotate the wiper blade assembly,
hold the wiper arm in position,
and push the blade away
from the wiper arm.
3. Replace the wiper blade.
4. Return the wiper arm and blade
assembly to the rest position on
the glass.
Tires
Your new vehicle comes with
high-quality tires made by a
leading tire manufacturer.
If you ever have questions about
your tire warranty and where to
obtain service, see your vehicle
Warranty booklet for details.
For additional information refer
to the tire manufacturer.
{CAUTION
Poorly maintained and
improperly used tires are
dangerous.
Overloading your
vehicle’s tires can cause
overheating as a result
of too much exing. You
could have an air-out and
a serious accident. See
Loading the Vehicle on
page 4-16.
(Continued)
CAUTION (Continued)
Underinated tires pose
the same danger as
overloaded tires. The
resulting accident could
cause serious injury.
Check all tires frequently to
maintain the recommended
pressure. Tire pressure
should be checked when
your vehicle’s tires are
cold. SeeInflation - Tire
Pressure on page 5-41.
Overinated tires are more
likely to be cut, punctured,
or broken by a sudden
impact — such as when
you hit a pothole. Keep
tires at the recommended
pressure.
Worn, old tires can cause
accidents. If the tire’s tread
is badly worn, or if your
vehicle’s tires have been
damaged, replace them.

aspect ratio is 60, as shown in
item C of the illustration, it would
mean that the tire’s sidewall is
60 percent as high as it is wide.
(D) Construction Code
:A letter
