Periodic Safety Checks You Should Make Outside
the Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect the tread and sidewall for
cuts and cracks. Check the wheel nuts for tightness.
Check the tires (including spare) for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid, or
brake fluid leaks are suspected, the cause should be
located and corrected immediately.2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 77

WARNING!
A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal
operating conditions. This can cause a fire if you
drive slowly or park over flammable substances such
as dry plants or wood or cardboard, etc. This could
result in death or serious injury to the driver, occu-
pants or others.
22. Tire Pressure Monitoring Telltale Light Each tire, including the spare (if provided),
should be checked monthly, when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving
on a significantly under-inflated 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.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
184 UNDERSTANDING YOUR INSTRUMENT PANEL
Page 186 of 450

maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the sys-
tem may not be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur for a variety
of reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the
TPMS malfunction telltale after replacing one or moretires or wheels on your vehicle, to ensure that the
replacement or alternate tires and wheels allow the TPMS
to continue to function properly.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can, or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.

STARTING AND OPERATING 247
Page 261 of 450

WARNING!
Always engage the parking brake when powering
down the vehicle if the “SVC 4WD Warning Light” is
illuminated. Not engaging the parking brake may
allow the vehicle to roll, which may cause personal
injury.
NOTE: Do not attempt to make a shift while only the
front or rear wheels are spinning. The NV233/243 trans-
fer case is not equipped with a synchronizer and there-
fore the front and rear driveshaft speeds must be equal
for the shift to take place. Shifting while only the front or
rear wheels are spinning can cause damage to the trans-
fer case. When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the 2WD or
4WD LOCK positions at a given road speed. Take care
not to overspeed the engine and do not exceed 25 mph
(40 km/h).
Proper operation of four-wheel drive vehicles depends
on tires of equal size, type and circumference on each
wheel. Any difference in tire size can cause damage to the
transfer case.
Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.

3. Replace tires when tread wear indicators first become
visible.
4. Keep tires properly inflated.
5. Maintain sufficient distance between your vehicle and
the car in front of you to avoid a collision in a sudden
stop.
DRIVING THROUGH WATER
Driving through water more than a few inches/
centimeters deep will require extra caution to ensure
safety and prevent damage to your vehicle.
Flowing/Rising Water
WARNING!
Do not drive on or across a road or path where water
is flowing and/or rising (as in storm run-off). Flow-
ing water can wear away the road or path’s surface
and cause your vehicle to sink into deeper water.
Furthermore, flowing and/or rising water can carry
your vehicle away swiftly. Failure to follow this
warning may result in injuries that are serious or
fatal to you, your passengers, and others around you.
Shallow Standing Water
Although your vehicle is capable of driving through
shallow standing water, consider the following Caution
and Warning before doing so.

STARTING AND OPERATING 265
Page 273 of 450
WARNING!
Pumping of the Anti-Lock Brakes will diminish their
effectiveness and may lead to an accident. Pumping
makes the stopping distance longer. Just press firmly
on your brake pedal when you need to slow down or
stop.
WARNING!
•Anti-Lock Brake Systems (ABS) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase braking or steering
efficiency beyond that afforded by the condition
of the vehicle brakes and tires or the traction
afforded.(Continued)
WARNING! (Continued)
•The ABS cannot prevent accidents, including
those resulting from excessive speed in turns,
following another vehicle too closely, or hydro-
planing. Only a safe, attentive, and skillful driver
can prevent accidents.
•The capabilities of an ABS-equipped vehicle must
never be exploited in a reckless or dangerous
manner, which could jeopardize the user’s safety
or the safety of others.
