220 Driving and Operating
Warning (Continued)
‐When driving over road
joints or bumps such as
light reflectors on the road.
‐ When driving on a bumpy
road, stone-paved road or
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.

222 Driving and Operating
Inspection
Pull the parking brake lever slowly
from the fully released position while
counting the clicks produced as the
lever engages ratchet plate notches
to check that it can be raised the
proper amount and the lever is held
firmly.
If the number of notches is not
within the standard value range
below, adjust it to the standard
value. Lever stroke is 6 to 8
notches.
Number of notches before parking
brake is set when lever is pulled
slowly from released position withpull force of about 147 N (15 kgf/
33 lbs).
See
Maintenance Schedule 0345
and Additional Maintenance and
Care 0375.
Exhaust Brake
(Diesel Only)
Exhaust Brake Switch
When turned on, the system
increases the amount of power
absorbed by the engine while
coasting in gear. Whenever slowing
down the vehicle, such as on down
grades, in city traffic or approaching
stop signals, this brake system may
be used.
To turn on the exhaust brake system
while driving, pull the lever
backward. The exhaust brake
indicator light comes on. For
vehicles with the 3.0L diesel engine,
the exhaust brake will engage
automatically when the accelerator
pedal is released and vehicle speed
is above 5 km/h (3 MPH). For
vehicles with the 5.2L diesel engine,
the exhaust brake will engage

Driving and Operating 223
automatically when the accelerator
pedal is released and vehicle speed
is above 10 km/h (6.5 MPH).
The exhaust brake will disengage
when the accelerator pedal or brake
pedal is pressed. Releasing the
pedal reengages the exhaust brake.
Push the lever forward to turn the
exhaust brake off during idling.
{Warning
It is extremely dangerous to apply
the exhaust brake on slippery
roads as the tires can skid.
You and others could be seriously
injured.
Even if the selector lever is placed
in the N position, the exhaust brake
does not disengage until the engine
is warmed up if the warm-up system
is on. Conditions for Inoperable Exhaust
Brake
Under the following conditions, the
exhaust brake does not engage
even if the exhaust brake indicator
light comes on:
.
The accelerator pedal is
pressed.
. The selector lever is in the N
position.
. The vehicle is traveling at
5 km/h (3 MPH) or lower speeds.
If your vehicle is equipped with an
anti-lock brake system (ABS), the
exhaust brake may disengage
during ABS operation even when
the exhaust brake switch is in the
ON position and the exhaust brake
indicator light is on. The exhaust
brake may disengage temporarily as
the vehicle passes over a bump
even when the brake pedal is not
depressed.
It is advisable to operate the
exhaust brake when descending a
slope or when stop and go driving is
involved. The selection of transmission gears
and engine speed when operating
the brake system is important. The
exhaust brake is more effective in
the lower gears and at the higher
engine speeds. See
Exhaust Brake
Light 088.

Vehicle Care 281
Never mix the specified brake fluid
with fluids of another brand.
Be careful not to spill brake fluid
onto painted surfaces or to let it
come in contact with skin. If fluid is
spilled onto a painted surface or
comes in contact with skin, wash
away the fluid with water and
immediately wipe the area clean.
Brake fluid readily absorbs moisture.
Therefore, it is necessary to close
the brake fluid container tightly for
storage.
If the brake fluid level decreases
rapidly, there may be a problem in
the brake system or brake pads or
shoe linings may have worn out.
Have your vehicle inspected by the
nearest dealer immediately.Battery

342 Vehicle Care
Dust and loose dirt that collect on
interior fabric should be removed
often with a vacuum cleaner or soft
bristle brush. Wipe vinyl or leather
trim regularly with a clean, damp
cloth. Normal trim soils, spots or
stains can be cleaned with these
cleaners.
Remember these basic steps before
cleaning:
.Remove stains as quickly as
possible before they
become "set".
. Use a clean cloth or sponge,
and change to a clean area
often. A soft brush maybe used
if stains persist.
. Use solvent-type cleaners only
in a well ventilated area: also, do
not saturate the stained area.
. If a ring forms after spot
cleaning, clean the entire area
immediately.
. Follow specific instructions on
cleaner labels.General Cleaning of Soiled or
Water Spotted Fabric Type
Trim with Foam Type Cleaner
Vacuum the area thoroughly to
remove any loose dirt.
Always clean a whole trim panel or
section. Mask surrounding trim
along stitch or welt lines.
Use suds on a clean sponge. Do
not brush wet suede. Do not
saturate the material or rub it
harshly. Immediately after cleaning,
remove suds with a sponge and
rinse with a clean wet sponge. Wipe
off remaining residue with a slightly
damp absorbent towel or cloth.
Important —Immediately after
wiping, force-dry the fabric with an
air hose. A heat dryer or heat lamp
may be used. Use caution with a
heat dryer or lamp to help prevent
damage.
When trim materials with a sheen or
luster finish are dry, wipe the fabric
lightly with a soft, dry, clean cloth to
restore its sheen or luster. For suede, raise nap with dry scrub
brush and vacuum to remove any
final traces of residue.Spot Cleaning Fabric Type
Trim with Solvent Type Cleaner
Before trying to remove a spot or
stain from fabric, try to find out the
type and age of the spot or stain.
Some spots or stains can be
removed with water or a mild soap
solution. Spots or stains should
always be removed as soon as
possible.
Some types of stains or soilage,
such as lipstick, inks and grease,
are very difficult (sometimes
impossible) to remove completely.
When cleaning this type of stain or
soilage, be sure not to enlarge the
soiled area.
.
Gently scrape excess stain from
the trim material with a clean,
dull knife or scraper. Use very
little cleaner, light pressure, and
clean cloths (preferably
cheesecloth). Cleaning should
start at the outside of the stain
