What to do in an emergency
6
Always follow these emergency tow-
ing precautions:
While depressing the brake pedal
shift to the N (Neutral) position and
turn the vehicle off. The POWER
button will be in the ACC position.
Release the parking brake.
Depress the brake pedal with more
force than normal since you will
have reduced braking perform-
ance.
More steering effort will be
required because the power steer-
ing system will be disabled.
Use a vehicle heavier than your
own to tow your vehicle.
The drivers of both vehicles should
communicate with each other fre-
quently.
Before emergency towing, check
that the hook is not broken or dam-
aged.
Fasten the towing cable or chain
securely to the hook.
Do not jerk the hook. Apply steady
and even force. Use a towing cable or chain less
than 16 feet (5 m) long. Attach a
white or red cloth (about 12 inch
(30 cm) wide) in the middle of the
cable or chain for easy visibility.
Drive carefully so the towing cable
or chain remains tight during towing.
Before towing, check the reduction
gear for fluid leaks under your vehi-
cle. If the reduction gear is leaking,
flatbed equipment or a towing dolly
must be used.Accelerate or decelerate the vehi-
cle in a slow and gradual manner
while maintaining tension on the
tow rope or chain to start or drive
the vehicle, otherwise tow hooks
and the vehicle may be damaged.
To avoid damage to your vehicle
and vehicle components when
towing:
Always pull straight ahead when
using the towing hooks. Do not
pull from the side or at a vertical
angle.
Do not use the towing hooks to
pull a vehicle out of mud, sand
or other conditions from which
the vehicle cannot be driven out
under its own power.
Limit the vehicle speed to
10 mph (15 km/h) and drive less
than 1 mile (1.5 km) when towing
to avoid serious damage to the
reduction gear.

Maintenance
While operating your vehicle:
Check for vibrations in the steering
wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead posi-
tion.
Notice if your vehicle constantly
turns slightly or "pulls" to one side
when traveling on smooth, level
road.
When decelerating with your vehi-
cle, listen and check for unusual
sounds, pulling to one side,
increased brake pedal travel or
"hard-to-push" brake pedal.
After driving your vehicle on a
regular basis check the follow-
ing:
Verify that the electronic parking
brake is engaging properly.
After you exit the vehicle check for
any signs of fluid leaks under your
vehicle (note that water dripping
from the air conditioning system is
normal).
At least monthly:
Check coolant level in the coolant
reservoir.
Check the operation of all exterior
lights, including the brake lights,
turn signals and hazard warning
flashers.
Check the inflation pressures of all
four tires and check to see the tire
tread condition and if there are any
signs of abnormal wear or dam-
age.
Check for loose wheel lug nuts.
At least twice a year:
Check radiator, heater and air con-
ditioning hoses for leaks or dam-
age.
Check windshield washer spray
and wiper operation. Clean wiper
blades with clean cloth dampened
with washer fluid.
Check headlamp alignment.
Check the seat belts for wear and
function.
At least once a year:
Clean body and door drain holes.
Lubricate door hinges and hood
hinges.
Lubricate door and hood locks and
latches.
Lubricate door rubber weather
strips.
Lubricate door checker.
Check the air conditioning system.
Inspect and lubricate reduction
gear linkage and controls.
Clean the battery and terminals.
Check the brake fluid level.

Cooling System
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Reduction Gear Fluid
Inspect the reduction gear fluid
according to the maintenance sched-
ule.
Brake Hoses and Lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.
Brake Fluid
Check brake fluid level in the brake
fluid reservoir. The level should be
between the MIN and the MAX
marks on the side of the reservoir.
Use only hydraulic brake fluid con-
forming to DOT 3 or DOT 4 specifi-
cation.
Brake Discs, Pads, Calipers
and Rotors
Check the pads for excessive wear,
discs for run out and wear, and
calipers for fluid leakage.
Suspension Mounting Bolts
Check the suspension connections
for looseness or damage. Retighten
to the specified torque.
Steering Gear Box, Linkage &
Boots/Lower Arm Ball Joint
With the vehicle stopped and the
vehicle off, check for excessive free-
play in the steering wheel. Check the
linkage for bends or damage. Check
the dust boots and ball joints for
deterioration, cracks, or damage.
Replace any damaged parts.
Drive Shafts and Boots
Check the drive shafts, boots and
clamps for cracks, deterioration, or
damage. Replace any damaged
parts and, if necessary, repack the
grease.
