9-38 Driving and Operating
Drive Systems
All-Wheel Drive
With this feature, engine power is
always sent to all four wheels. It is
fully automatic, and adjusts itself as
needed for road conditions.
When using a compact spare tire on
an AWD vehicle, the system
automatically detects the compact
spare and disables AWD. To restore
AWD operation and prevent
excessive wear on system, replace
the compact spare with a full-size
tire as soon as possible. See
Compact Spare Tire
on page 10‑73for more information.
Brakes
Antilock Brake
System (ABS)
This vehicle has the Antilock Brake
System (ABS), an advanced
electronic braking system that helps
prevent a braking skid.
When the engine is started and the
vehicle begins to drive away, ABS
checks itself. A momentary motor or
clicking noise might be heard while
this test is going on, and it might
even be noticed that the brake
pedal moves a little. This is normal.
If there is a problem with ABS, this
warning light stays on. SeeAntilock
Brake System (ABS) Warning Light
on page 5‑19. If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to
avoid a sudden obstacle, a
computer senses that the wheels
are slowing down. If one of the
wheels is about to stop rolling, the
computer will separately work the
brakes at each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
the driver steer around the obstacle
while braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.

2. Push the release lever (B) todisengage the hook and push
the wiper arm (A) out of the
blade (C).
3. Push the new wiper blade securely on the wiper arm until
you hear the release lever click
into place.
4. Return the wiper arm and blade assembly to the rest position on
the windshield. To replace the rear wiper blade:
1. Lift the rear wiper arm (A) from
the window.
2. Turn the bottom edge of the blade assembly (B) slightly away
from the underside of the
wiper arm.
3. Apply downward pressure to the blade assembly and remove
from the wiper arm.
4. Install the new wiper blade.
5. Return the wiper arm and blade assembly to the rest position on
the window.
Headlamp Aiming
The headlamp aiming system has
been preset at the factory.
If the vehicle is damaged in an
accident, the aim of the headlamps
may be affected and adjustment
may be necessary.
It is recommended that a dealer/
retailer adjust the headlamps.
To re-aim the headlamps yourself,
use the following procedure.
The vehicle should be properly
prepared as follows:
.The vehicle should be placed so
the headlamps are 7.6 m (25 ft)
from a light colored wall.
.The vehicle must have all
four tires on a level surface
which is level all the way to
the wall.

Wheels and Tires
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.
{WARNING
Poorly maintained and improperly
used tires are dangerous.
.Overloading your tires can
cause overheating as a result
of too much flexing. You
could have an air-out and a
serious accident. SeeVehicle
Load Limits on page 9‑22.
.Underinflated 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
tires are cold. See Tire
Pressure on page 10‑50.
(Continued)
WARNING (Continued)
.Overinflated 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 your tread is
badly worn, or if your tires
have been damaged,
replace them.

Tire Pressure
Tires need the correct amount
of air pressure to operate
effectively.
Notice:Do not let anyone tell
you that under‐inflation or
over‐inflation is all right. It is
not. If your tires do not have
enough air (under‐inflation),
you can get the following:
.Too much flexing
.Too much heat
.Tire overloading
.Premature or
irregular wear
.Poor handling
.Reduced fuel economy If your tires have too much air
(over‐inflation), you can get
the following:
.Unusual wear
.Poor handling
.Rough ride
.Needless damage from
road hazards
A vehicle specific Tire and
Loading Information label is
attached to your vehicle.
This label shows your vehicle's
original equipment tires and the
correct inflation pressures for
your tires when they are cold. The recommended cold tire
inflation pressure, shown on the
label, is the minimum amount of
air pressure needed to support
your vehicle's maximum load
carrying capacity.
For additional information
regarding how much weight
your vehicle can carry, and an
example of the Tire and Loading
Information label, see
Vehicle
Load Limits
on page 9‑22.
How you load your vehicle
affects vehicle handling and ride
comfort. Never load your vehicle
with more weight than it was
designed to carry.

Vehicle Care 10-51
When to Check
Check your tires once a month
or more. Do not forget to
check the compact spare tire,
if the vehicle has one. The
compact spare should be at
60 psi (420 kPa). For additional
information regarding the
compact spare tire, see
Compact Spare Tire
on
page 10‑73
.
How to Check
Use a good quality pocket-type
gage to check tire pressure.
You cannot tell if your tires are
properly inflated simply by
looking at them. Radial tires
may look properly inflated even
when they are under‐inflated. Check the tire's inflation
pressure when the tires are
cold. Cold means your vehicle
has been sitting for at least
three hours or driven no more
than 1.6 km (1 mile).
Remove the valve cap from the
tire valve stem. Press the tire
gage firmly onto the valve to get
a pressure measurement. If the
cold tire inflation pressure
matches the recommended
pressure on the Tire and
Loading Information label, no
further adjustment is necessary.
If the inflation pressure is low,
add air until you reach the
recommended amount.
If you overfill the tire, release air
by pushing on the metal stem
in the center of the tire valve.
Re‐check the tire pressure with
the tire gage.
Be sure to put the valve caps
back on the valve stems.
They help prevent leaks by
keeping out dirt and moisture.
