must park your vehicle on a slope,
be sure to set the parking brake
fully. Make sure that the vehicle
does not move, and block the
wheels with chocks for added
safety. Also, leave the vehicle in
gear to further ensure that it will not
move. Leave the steering wheel
turned such that the vehicle will be
stopped by an obstruction (for
example, the curb) in the unlikely
event that it moves.
Stopping and Parking with the
Engine Running
{Warning
When parking with the engine
running, first come to a complete
stop, then firmly apply the parking
brake, then move the selector
lever to the "P" (Park) position.
Unless you take these steps, any
unintended pressure on the
accelerator pedal could cause an
accident.(Continued)
Warning (Continued)
To reduce the chance of personal
injury and/or vehicle damage due
to engine overheating, never
leave the engine idling without an
alert driver present. If the engine
should overheat, as indicated by
the engine coolant temperature
gauge, immediate action is
required to correct the condition.
Continued operation of the
engine, even for a short time, may
result in a fire. Do not engage the
exhaust brake while the engine is
idling as this may cause engine
overheating.
The diesel particulate filter (DPF)
may automatically start
regeneration when the vehicle is
stopped and parked with the
engine running. To prevent a fire,
make sure there is no flammable
material near the muffler, DPF,
and exhaust pipe. Be careful not
to get burned by hot exhaust
gases.(Continued)
Warning (Continued)
You and others could be seriously
injured.
Do Not Forget to Release the
Parking Brake
Pulling away with the parking brake
still applied can damage the brake
system.
Before pulling away, make sure the
parking brake is not set by checking
that the parking brake indicator light
is not on.
Be Sure to Have the Engine
Running When the Vehicle is
Moving
{Warning
When the engine is not running,
the power steering system does
not work so the steering wheel is
hard to turn. Also, the brake
booster does not work so there is
little braking ability. If you coast (Continued)

personal injury. Before parking
the vehicle in winter, press the
brake pedal several times in the
same way to get rid of moisture in
the brakes. Otherwise, the
moisture in the brakes may freeze
and make the vehicle immovable.
You and others could be seriously
injured.
If the vehicle must be driven on a
flooded road or is parked in an area
that becomes flooded, promptly
perform a check for the following
points:
. Effectiveness of the brakes
. Water-ingress or damage to
drum brakes, disc brakes
. Engine damage due to
water-ingress
. Shorting of electrical
components .
Oil level and degradation
(cloudiness) of the engine,
transmission, differential
. Greasing of each components
(lubrication)
Steering
Do Not Leave the Steering
Wheel Fully Turned for a
Long Time
{Warning
If you leave the steering wheel
fully turned for a long time, the oil
in the power steering oil pump will
become extremely hot. This
would cause poor lubrication, oil
tank damage and seal
deterioration, leading to power
steering oil pump damage, power
steering unit damage and power
steering hose damage. As a
result the steering wheel could
become extremely hard to turn
and a fire or other accident could
occur.
(Continued)
Warning (Continued)
You and others could be seriously
injured.
Steering Wheel
If the steering parts have excess
play or looseness or if any abnormal
condition is noted, have the steering
system checked immediately.
Driving on Wet Roads
Driving on Slippery Surface or
Driving in Bad Weather (Rain,
Icy Roads, Snowy Roads, etc.)
In bad weather, visibility is reduced
and slippery road surfaces increase
stopping distances. Drive more
slowly than you would in good
weather. Also, avoid sharp turns of
the steering wheel and hard
braking. Use engine brakes together
with the foot brakes to decelerate.
For diesel vehicles, using the
exhaust brake on a slippery road
surface could cause the tires to slip.

146 Driving and Operating
When Ice Prevents You from
Putting Your Key in the Door
or Opening the Door
If you try to force the key into the
door, you could bend it. And if you
try to pull the door open with undue
force, the rubber seal around the
door could come unstuck or become
damaged. Use warm water to melt
the ice, then quickly wipe it away
and open the door.
If the wipers, electric door mirrors,
or power windows freeze up, also
use warm water to melt the ice and
then operate the system. Otherwise,
you could damage the mechanism
and drain the battery. After that,
wipe the water away.
Before Driving in Cold Regions
Getting In and Out of the Vehicle
The step can get icy in cold regions.
Be careful not to slip when getting in
and out of the vehicle.
Before Sitting in the Driver’s Seat
Remove snow and ice from your
shoes when getting into the vehicle.
If you try to drive with snow on your shoes, your shoes would slip on the
pedals and you would not be able to
press the pedals properly, meaning
that your driving would be
inconsistent. Also, the cabin could
become more humid, causing the
glass to fog up.
Check Fuel Level
Fuel consumption increases when
tire chains are used. Determine how
much fuel you need to reach your
destination and fill up the tank in
advance. Refer to
Fuel for Diesel
Engines 0232 orFuel (Gasoline)
0 231.
Removing Snow from Glass
and Underbody
Do not use a sharp implement to
remove snow. Sharp edges could
damage rubber parts.
To maintain an adequate field of
view, use a plastic scraper to
remove snow and frost from the
glass surfaces. By using a plastic
scraper, you can remove the snow
and frost without scratching the glass. At this time, check whether
the wiper blades are frozen onto the
glass.
Also, look under the vehicle and
remove any lumps of ice that are
stuck to the underbody. Be careful
not to damage components.
Driving on Snowy or Frozen
Roads
On slippery roads, never accelerate
rapidly, brake hard, decelerate
rapidly or make sharp turns of the
steering wheel.
There is a risk of reduced grip
between the tires and road surface
and of increased braking distances.
The danger of icy road surfaces is
particularly great on bridges, in
shady places and where there are
puddles.
Keep your speed down and be sure
to use tire chains or winter tires on
snowy or frozen road surfaces.
For diesel vehicles, use engine
brakes together with the foot brakes
to decelerate. Using the exhaust
brake on a slippery road surface
could cause the tires to slip.

.Do not use a sharp implement to
remove snow. Sharp edges
could damage rubber parts.
Refer to Antilock Brake System
(ABS) 0217.
Remove snow that has stuck to the
inside of the fenders and to the
brake hoses. Otherwise, it may
damage components. After driving
on a salted road, wash the
underside of the vehicle as soon as
possible to prevent the salt from
causing rust. Spraying water under
high pressure is an effective way to
get the salt off.
After washing the vehicle, wipe the
door openings dry.
If the Vehicle Is Stuck
When Driving on Bad Roads
Freeing the Vehicle from Sand,
Mud, Snow, and Ice
If your vehicle gets stuck in sand,
mud, snow or ice, move the selector
lever from "Second" to "Reverse".
Apply a light pressure to the
accelerator pedal while the
transmission is in gear. Remove your foot from the accelerator and
press the brake pedal while shifting.
Do not race the engine. For best
traction, avoid spinning the wheels.
When you cannot avoid driving
through deep mud, using tire chains
is an effective way to avoid getting
stuck.
Do not allow wheels to spin freely in
mud, sand, snow, ice or other poor
road conditions. This free spinning
will damage the rear axle. Even
vehicles equipped with LSD (Limited
Slip Differential) have traction
limitations. If your vehicle gets stuck
and it is difficult to extricate,
immediately stop driving and have
the vehicle towed. Spinning wheels
for an extended period of time may
cause abnormal noises or
malfunction to LSD.
Do not spin wheels faster than
32 km/h (20 MPH). Damage may
result from excessive wheel
spinning, including tire, transmission
and/or rear axle malfunction.
When driving in sand or mud, avoid
hard braking, sudden acceleration
and sharp turns of the steering
wheel. Such actions could get the
vehicle stuck and make it difficult to
extricate.
After driving through deep mud: any
mud stuck to the vehicle can harm
the steering, brakes and powertrain.
Wash the vehicle and remove all
mud and other incrustation.
The vehicle speed sensors are fitted
on the wheels. When removing mud
and other incrustation, take great
care not to damage the
components.
Do not use a sharp implement to
remove mud. Sharp edges could
damage rubber parts.

with the following in mind.
The power steering system will
not work so the steering wheel
will be hard to turn. It will require
more strength than during normal
operation.
As the brake booster will no
longer be functional, brake
effectiveness will be greatly
reduced. Be sure to apply more
pressure than usual to the brake
pedal.
If the power assist steering
system goes out because the
engine has stopped or the assist
system has malfunctioned, the
vehicle can still be steered.
However, much greater effort is
needed, especially in sharp turns
or at low speeds.
You or others could be seriously
injured. When the Vehicle Breaks Down
During Driving
1. Use the hazard warning flasher any time to warn other drivers,
day or night, and pull the

track.
‐ When driving over an iron
plate or manhole lid.
ABS does not work for wheel skid
during a standing start,
acceleration and cornering which
do not involve braking. On a very
slippery icy road, tires may lose
grip and steering wheel operation
may not be able to control the
vehicle's direction, resulting in
very unstable driving. Always
drive the vehicle observing a safe
speed well matched with both
road surface and tire conditions,
and avoid sudden braking.
If powerful engine braking is
applied on a very slippery icy
road, the drive wheels may be (Continued)
Warning (Continued)
locked (the ABS then does not
work), resulting in loss of vehicle
control.
When ABS is activated, a slight
vibration (especially when the
road surface is different between
right and left wheels) and pulling
may be felt on the brake pedal
and steering wheel. In addition,
an operating sound is produced
from the ABS actuators. This
does not indicate any abnormal
condition. Stay calm and operate
the steering wheel properly.
Electronic Braking force
Distribution (EBD)
EBD is a function that uses the ABS
to distribute braking force ideally
between the front and rear wheels
in order to compensate for changes
in load conditions or any shift of the
load due to acceleration or
deceleration, thus preventing
premature locking of the rear
wheels.
{Warning
If a problem should occur with the
EBD function, the ABS warning
light and the brake system
warning light will come on
simultaneously.
The rear wheels will lock more
easily if there is a problem with
the EBD function. Have it
checked and serviced at the
nearest dealer as soon as
possible. You and others could be
seriously injured.
When the EBD operates, the brake
pedal may push back slightly or you
may hear a sound similar to that
generated by the ABS when
operational. Neither of them
indicates any abnormal condition.
