Maintenance

Exhaust pipe and muffler
Visually inspect the exhaust pipes,
muffler and hangers for cracks, dete-
rioration, or damage. Start the
engine and listen carefully for any
exhaust gas leakage. Tighten con-
nections or replace parts as neces-
sary.
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 engine
off, check for excessive free-play in
the steering wheel.
Check the linkage for bends or dam-
age. 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.
Air conditioning refrigerant
Check the air conditioning lines and
connections for leakage and dam-
age.When checking engine oil, engine
coolant, brake fluid, and washer fluid,
always be sure to clean the area
around any filler plug, drain plug, or
dipstick before checking or draining
any lubricant or fluid. This is espe-
cially important in dusty or sandy
areas and when the vehicle is used
on unpaved roads. Cleaning the plug
and dipstick areas will prevent dirt
and grit from entering the engine and
other mechanisms that could be
damaged.

Maintenance
Taking care of leather seats
Vacuum the seat periodically to
remove dust and sand on the seat.
It will prevent abrasion or damage of
the leather and maintain its quality.
Wipe the natural leather seat cover
often with dry or soft cloth.
Sufficient use of a leather protec-
tive may prevent abrasion of the
cover and helps maintain the color.
Be sure to read the instructions
and consult a specialist when
using leather coating or protective
agents.
Leather with bright colors(beige,
cream beige) is easily contaminat-
ed and clear in appearance. Clean
the seats frequently.
Avoid wiping with wet cloth. It may
cause the surface to crack.
Cleaning the leather seats
Remove all contaminations instant-
ly. Refer to instructions below for
removal of each contaminant.
Cosmetic products(sunscreen,
foundation, etc.)
- Apply cleansing cream on a cloth
and wipe the contaminated point.
Wipe off the cream with a wet
cloth and remove water with a dry
cloth.
Beverages(coffee, soft drink, etc.)
- Apply a small amount of neutral
detergent and wipe until contami-
nations do not smear.
Oil
- Remove oil instantly with
absorbable cloth and wipe with
stain remover for natural leather
only.
Chewing gum
- Harden the gum with ice and
remove gradually.CAUTION - Electrical
components
Never allow water or other liq-
uids to come in contact with
electrical/electronic compo-
nents inside the vehicle as this
may damage them.
CAUTION - Leather
When cleaning leather products
(steering wheel, seats etc.), use
neutral detergents or low alco-
hol content solutions. If you use
high alcohol content solutions
or acid/alkaline detergents, the
color of the leather may fade or
the surface may get stripped off.
