VTM-4 LOCK BUTTON
Your vehicle is equipped with a
variable torque management
4-wheel-drive system (VTM-4) that
distributes engine torque to the
appropriate drive axle depending on
the available traction conditions. The
system is completely automatic,
always active, and does not require
any driver interaction.
198
If you become stuck, you can
activate the VTM-4 by pressing the
VTM-4 LOCK button while in first
(1), second (2), or reverse (R) gear
below 18 mph (30 km/h). This mode
overrides the auto system to send
maximum torque to the rear axle.
This mode is only intended for
intermittent use at low speed to free
your vehicle if it becomes stuck or
when you encounter a steep grade
with one wheel on a slippery surface.
Generally, you should first allow the
auto mode to operate to adjust for
the available traction conditions.
To Engage the VTM-4 Lock:
1. The vehicle speed must be below
18 mph (30 km/h).
2. Move the shift lever to first (1),
second (2), or reverse (R) gear.
3. Press the VTM-4 LOCK button.
The indicator in the button comes
on.
To get unstuck, apply light pressure
to the accelerator pedal. Do not spin
the front tires for more than a few
seconds. Because of the amount of
torque applied to the rear tires, they
should not spin. This is normal. If
you are not able to move the vehicle,
stop and reverse direction.
Do not use the VTM-4 LOCK button on
dry, paved roads. Driving on dry,
paved roads with VTM-4 Lock ON may
damage the rear dif f erential when
making a turn. Strange noise and
vibration can also result.

The VTM-4 Lock will temporarily
disengage when the vehicle speed
exceeds 18 mph (30 km/h). The
indicator in the button will remain on.
To Disengage the VTM-4 Lock, do
any of the following:
Press the VTM-4 LOCK button.
Move the shift lever to D.
Each tire has its own pressure
sensor. If the air pressure of a tire
becomes significantly low, the
sensor in that tire immediately sends
a signal that causes the low tire
pressure indicator and the
appropriate tire on the tire pressure
monitor to come on.
Low Tire Pressure
Indicator
When this indicator is on, one or
more of your tires is significantly
under inflated. You should stop and
check your tires as soon as possible.
If you think you can safely drive a
short distance to a service station,
proceed slowly, and inflate the tire to
the recommended pressure shown
on the driver’s doorjamb.
If the tire is flat, or if the tire
pressure is too low to continue
driving, replace the tire with the
compact spare tire.
Do not continuously spin the front tires
of your vehicle. Continuously spinning
the f ront tires can cause transmission
or rear dif f erential damage.

Driving
Turn the ignition switch to the
LOCK (0) position.
Tire Pressure Monitoring System
(TPMS)
Your vehicle is equipped with a tire
pressure monitoring system (TPMS)
that turns on every time you start the
engine and monitors the pressure in
your tires while driving.

Driving on a significantly underinflated tire causes the tire to
overheat and can lead to tire failure.
Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle’s handling and
stopping ability.
Although your tire pressure is
monitored, each tire should be
checked monthly, including the
spare.
Check the pressure with the tires
cold, after the vehicle has been
parked for at least 3 hours.
Set to the recommended inflation
pressure as specified on the vehicle
placard and in this owner’s manual
(see page 256 ).
200
Tire Pressure Monitor
The appropriate tire indicator and
low tire pressure indicator comes on
if a tire becomes significantly
underinflated. See Low Tire
Pressure Indicator on page 199 .
Tire Pressure Monitoring
System (TPMS) Indicator
This indicator comes on and stays on
if there is a problem with the tire
pressure monitoring system.
If this happens, the system will shut
off and no longer monitor tire
pressures. Have the system checked
by your dealer as soon as possible.
Changing a Tire with TPMS
If you have a flat tire, the low tire
pressure and tire monitor indicators
will come on. Replace the indicated
flat tire with the compact spare tire
(see page 265 ).
Each wheel is equipped with a tire
pressure sensor mounted inside the
tire behind the valve stem. You must
use TPMS specific wheels. It is
recommended that you always have
your tires serviced by your dealer or
qualified technician.
After you replace the flat tire with the
compact spare tire, the low tire pressure
indicator stays on. This is normal;
the system is not monitoring the spare
tire pressure. Manually check the
spare tire pressure to be sure it is
correct.
Never use a puncture-repairing agent
in a flat tire. If used, you will have to
replace the tire pressure sensor.
Have the flat tire repaired by your
dealer as soon as possible.

If the vehicle is facing uphill, turn
the front wheels away from the
curb, and set the parking brake.
If the vehicle is facing downhill,
turn the front wheels toward the
curb, and set the parking brake.
Make sure the parking brake is
fully released before driving away.
Driving with the parking brake
partially set can overheat or
damage the parking brake.
Braking System
Your vehicle is equipped with disc
brakes at all four wheels. A power
assist helps reduce the effort needed
on the brake pedal. The anti-lock
brake system (ABS) helps you retain
steering control when braking very
hard.
Resting your foot on the pedal keeps
the brakes applied lightly, builds up
heat, increases wear, and reduces
their effectiveness. It also keeps
your brake lights on all the time,
confusing drivers behind you.
Constant application of the brakes
when going down a long hill builds
up heat and reduces their effectiveness. Use the engine to assist the
brakes by taking your foot off the
accelerator and downshifting to a
lower gear.
202
Check the brakes after driving
through deep water. Apply the
brakes moderately to see if they feel
normal. If not, apply them gently and
frequently until they do. Be extra
cautious in your driving.
Braking System Design
The hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the vehicle (the left-front brake is
connected with the right-rear brake,
etc.). If one circuit should develop a
problem, you will still have braking
at two wheels.
Brake Wear Indicators
If the brake pads need replacing, you
will hear a distinctive, metallic
screeching sound when you apply
the brake pedal. If you do not have
the brake pads replaced, they will
screech all the time. It is normal for
the brakes to occasionally squeal or
squeak when you apply them.

04/12/03 16:49:23 31SJC600 0208 Anti-lock Brakes (ABS)
The anti-lock brake system (ABS)
helps prevent the brakes from
locking up, and helps you retain
steering control by pumping the
brakes rapidly, much faster than a
person can do it.
The ABS also balances the front-torear braking distribution according
to vehicle loading.
Let the ABS work for you by always
keeping firm, steady pressure on the
brake pedal. This is sometimes
referred to as ‘‘stomp and steer.’’
ABS Indicator
If the ABS indicator comes on, the
anti-lock function of the braking
system has shut down. The brakes
still work like a conventional system,
but without anti-lock. You should
have your dealer inspect your vehicle
as soon as possible.
If the indicator comes on while
driving, test the brakes as instructed
on page 280 .
CONTINUED
203
Driving
You should never pump the brake pedal.
You will feel a pulsation in the brake
pedal when the ABS activates, and
you may hear some noise. This is
normal: it is the ABS rapidly
pumping the brakes. On dry
pavement, you will need to press on
the brake pedal very hard before the
ABS activates. However, you may
feel the ABS activate immediately if
you are trying to stop on snow or ice.

If the ABS indicator and the brake
system indicator come on together
and the parking break is fully
released, the front-to-rear braking
distribution system may also shut
down.
Test your brakes as instructed on
page 280 . If the brakes feel normal,
drive slowly and have your vehicle
repaired by your dealer as soon as
possible. Avoid sudden hard braking
which could cause the rear wheels to
lock up and possibly lead to a loss of
control.
The VSA indicator will come on
along with the ABS indicator.
204
Important Safety Reminders
ABS does not reduce the time or
distance it takes to stop the
vehicle. It only helps with steering
control during braking.
ABS will not prevent a skid that
results from changing direction
abruptly, such as trying to take a
corner too fast or making a sudden
lane change. Always drive at a safe
speed for the road and weather
conditions.
ABS cannot prevent a loss of
stability. Always steer moderately
when you are braking hard. Severe
or sharp steering wheel movement
can still cause your vehicle to veer
into oncoming traffic or off the road.
A vehicle with ABS may require a
longer distance to stop on loose or
uneven surfaces, such as gravel or
snow, than a vehicle without antilock. Slow down, and allow a greater
distance between vehicles under
those conditions.
