Driving could be dangerous. If you
judge it to be safe, drive carefully to
the nearest service station for re-
pairs. Otherwise, have your vehicle
towed.

Pressing the brake pedal with the
engine stopped and/or low brake
fluid level may increase your stop-
ping distance and braking will re-
quire greater pedal effort as well as
greater pedal travel.

If the brake fluid level is below the

Make sure the area around the vehicle is
clear.

Check fluid levels such as engine oil, coolant,
brake and clutch fluid, window washer fluid
as frequently as possible, at least whenever
you refuel.

Check to be sure that all windows and light
lenses are clean.

Visually inspect tires for their appearance and
condition. Also check tires for proper infla-
tion.

Move the selector lever to P (Park position) or
N (Neutral position). (P preferred)
The selector lever cannot be moved out
of P and into any of the other gear
positions if the ignition key is turned to
LOCK or if the key is removed from the
switch.
The starter is designed not to operate if
the selector lever is in one of the driving
positions.
Manual transmission:
Move the gearshift lever to N (Neutral posi-
tion), and depress the clutch pedal to the
floor while starting the engine.
The starter is designed not to operate

*1:
The transfer 4LO position indicator light
may blink. Stop the vehicle. Be sure to
shift the 4WD shift switch after the auto-
matic transmission lever has been shifted
to the N position. If the indicator light
keeps blinking after the 4WD shift proce-
dure in the previous page, drive slowly
without abrupt maneuvers for a while.
Then the light will turn on or off.

Avoid making a turn or abrupt starts while
shifting to 4LO. Otherwise gears may
grind, damaging the drive system.
*2: Make sure the transfer 4LO position indicator
light turns on when you shift the 4WD shift
switch to 4LO.
The transfer case 4WD shift switch is used to
select either 2WD or 4WD depending on the
driving conditions. There are four types of drive
modes available, AUTO, 2WD, 4H and 4LO.
The 4WD shift switch electronically controls the
transfer case operation. Rotate the switch to
move between each mode, 2WD, AUTO, 4H
and 4LO.
You must push the switch in to select 4LO,
and the vehicle MUST be stationary and
the automatic transmission selector lever
is in the Nposition when changing into or
out of 4LO.
WARNING
When parking, apply the parking brake
before stopping the engine and make
sure that the 4WD shift indicator light is
on and the ATP warning light goes off.
Otherwise, the vehicle could unexpect-
edly move even if the automatic trans-
mission is in the P position.
CAUTION

Never shift the 4WD shift switch be-
tween 4LO and 4H while driving.

The 4H position provides greater
power and traction. Avoid excessive
speed, as it will cause increased fuel
consumption and higher oil tempera-
ture, and could damage drivetrain
components. Speeds over 50 MPH
(80 km/h) in 4H are not recom-
mended.

The 4LO position provides maximum
power and traction. Avoid raising ve-hicle speed excessively, as the maxi-
mum speed is approximately 30 MPH
(50 km/h).

When driving straight, shift the 4WD
shift switch to the 2WD, AUTO or 4H
position. Do not move the 4WD shift
switch when making a turn or revers-
ing.

Do not shift the 4WD shift switch
(between 2WD, AUTO and 4H) while
driving on steep downhill grades. Use
the engine brake.

Do not operate the 4WD shift switch
(between 2WD, AUTO and 4H) with
the rear wheels spinning.

Do not drive on dry hard surface
roads in the 4H or 4LO position. Driv-
ing on dry hard surfaces in 4H or 4LO
may cause unnecessary noise and
tire wear. We recommend driving in
the 2WD or AUTO position under
these conditions.

ing and driving” section for exhaust gas (carbon
monoxide).
Underbody:
The underbody is frequently exposed to corro-
sive substances such as those used on icy roads
or to control dust. It is very important to remove
these substances, otherwise rust will form on the
floor pan, frame, fuel lines and around the ex-
haust system. At the end of winter, the under-
body should be thoroughly flushed with plain
water, being careful to clean those areas where
mud and dirt may accumulate. For additional
information, see “Cleaning exterior” in the “7.
Appearance and care” section.
Fluid leaks:
Check under the vehicle for fuel, oil, water or
other fluid leaks after the vehicle has been
parked for a while. Water dripping from the air
conditioner after use is normal. If you should
notice any leaks or if gasoline fumes are evident,
check for the cause and have it corrected imme-
diately.When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions which should be closely observed.
WARNING

Park the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For a manual
transmission, move the shift lever to
Neutral. For an automatic transmis-
sion, move the selector lever to the P
(Park) position.

Be sure the ignition key is in the OFF
or LOCK position when performing
any replacement or repair.

If you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving fans
belts and any other moving parts.

It is advisable to secure or remove
any loose clothing and any jewelry,such as rings, watches, etc. before
working on your vehicle.

Always wear eye protection when-
ever you work on your vehicle.

If you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.

Never get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle,
support it with safety stands.

Keep smoking materials, flame and
sparks away from fuel and battery.

Your vehicle is equipped with an au-
tomatic engine cooling fan. It may
come on at any time without warning,
even if the ignition key is in the OFF
position and the engine is not run-
ning. To avoid injury, always discon-
nect the negative battery cable be-
fore working near the fan.
