check the level. It should be
between the upper and lower
marks.
If it is near or below the lower mark,
see on page . Look at the coolant level in the
radiator reserve tank. Make sure it is
between the MAX and MIN lines. If
it is below the MIN line, see

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.When the low tire pressure indicator
is on, one or more of your tires is
signif icantly underinf lated. You
should stop and check your tires as
soon as possible, and inf late them to
the proper pressure as indicated on
the vehicle’s tire inf ormation placard.
If you think you can saf ely drive a
short distance to a service station,
proceed slowly, and inf late the tire to
the recommended pressure shown
on the driver’s doorjamb.
If the tire is f lat, or if the tire
pressure is too low to continue
driving, replace the tire with the
compact spare tire (see page ).
If you cannot make the low tire
pressure indicator go out af ter
inf lating the tires to the specif ied
values, have your dealer check the
system as soon as possible.Driving on a signif icantly under-
inf lated tire causes the tire to
overheat and can lead to tire failure.
Under-inf lation also reduces f uel
efficiency and tire tread life, and may
af f ect the vehicle’s handling and
stopping ability.
Becausetirepressurevariesby
temperature and other conditions,
the low tire pressure indicator may
come on unexpectedly.
Each tire has its own pressure
sensor (not including the spare tire).
If the air pressure of a tire becomes
signif icantly low, the sensor in that
tire immediately sends a signal that
causes the low tire pressure
indicator and the appropriate tire on
thetirepressuremonitortocomeon.

use TPMS specif ic wheels. It is
recommended that you always have
your tires serviced by your dealer or
a qualif ied technician.
After you replace the flat tire with

Before you leave the pavement, be
sure to do all scheduled maintenance
and service, and inspect your vehicle
f or any problems. Pay special
attention to the condition of the tires,
and check the tire pressures.
After you return to the pavement,
caref ully inspect your vehicle to
make sure there is no damage that
could make driving it unsaf e.
Recheck the condition of the tires
and the tire pressures.
The route presents limits (too steep
or bumpy roads). You have limits
(driving skill and comfort). And your
vehicle has limits (traction, stability,
and power).
Driving of f -highway can be
hazardous if you f ail to recognize
limits and take the proper
precautions.
To avoid loss of control or rollover,
be sure to f ollow all precautions and
recommendations.
Be sure to store cargo properly
and do not exceed your cargo load
limits (see page and ).
Be aware that a heavy load can
reduce ground clearance and your
ability to clear obstacles.
Whenever you drive, make sure
you and your passengers always
wear seat belts.
Keep your speed low, and never
go faster than the conditions allow.
It’s up to you to continually assess
the situation and drive within the
limits. 191217

The banks and surf ace under the
water provide good traction. The
water may hide hazards such as
rocks, holes, or mud.
Bef ore driving through water, stop,
get out if necessary, and make sure
that:
If you decide it is saf e to drive
through water, choose a suitable
speed, and proceed without shif ting,
changing speeds, stopping, or
shutting of f the engine.
Do not try to cross water at high
speeds, as this may cause severe
damage to the cooling system or
result in loss of control.
After driving through water, test
your brakes. If they got wet, gently
‘‘pump’’ them while driving slowly
until they operate normally.
If the water is deeper than the wheel
hubs, some additional service may
be required. This service is not
covered by your warranties.
The water is not f lowing too f ast.
Deep rushing water can sweep you
downstream. Even very shallow
rushingwatercanwashthe
ground f rom under your tires and
cause you to lose traction and
possibly roll over.
The banks are sloped so you can
drive out.
The water is not deep enough to
cover your wheel hubs, axles, or
exhaust pipe. You could stall and
not be able to restart your engine.
The water can also damage
important vehicle components. If you get stuck, and cannot get
unstuck with the VTM-4 system,
engage the VTM-4 Lock (see page
), and carefully try to go in the
direction (f orward or reverse) that
you think will get you unstuck. Do
notspinthetiresathighspeeds.It
will not help you get out and may
cause damage to the transmission or
VTM-4 system.
If you are still unable to f ree yourself ,
your vehicle is equipped with f ront
and rear tow hooks designed f or this
purpose (see page ). 299
