DOES YOUR VEHICLE NEED
REPAIRING?
Be on the alert for changes in performance and sounds, and
visual tip-offs that indicate service is needed. Some important
clues are:
Engine missing, stumbling, or pinging
Appreciable loss of power
Strange engine noises
A fluid leak under the vehicle (However, water dripping from
the air conditioning after use is normal.)
Change in exhaust sound (This may indicate a dangerous
carbon monoxide leak. Drive with the windows open and
have the exhaust system checked immediately.)
Flat-looking tires, excessive tire squeal when cornering,
uneven tire wear
Vehicle pulls to one side when driving straight on a level
road
Strange noises related to suspension movement
Loss of brake effectiveness, spongy feeling brake pedal,
pedal almost touches floors, vehicle pulls to one side when
braking
Engine coolant temperature continually higher than normalIf you notice any of these clues, take your vehicle to your Lexus
dealer as soon as possible. It probably needs adjustment or
repair.
CAUTION
Do not continue driving with the vehicle unchecked. It
could result in serious vehicle damage and possibly
personal injury.

Synthetic Leather Areas (Dash)
The synthetic leather areas may be easily cleaned with a
mild soap or detergent and water.First vacuum over the upholstery to remove loose dirt. Then,
using a sponge or soft cloth, apply the soap solution to the
synthetic leather. After allowing it to soak in for a few minutes
to loosen the dirt, remove the dirt and wipe off the soap with a
clean damp cloth. If all the dirt does not come off, repeat the
procedure. Commercial foaming-type cleaners are also
available which work well. Follow the manufacturer's
instructions.
NOTICE
Do not use solvent, thinner, gasoline or window cleaner
on the interior.
Carpets, Windows and Seat Belts
Begin by vacuuming thoroughly to remove as much dirt as
possible. Several types of foam cleaners are available; some
are in aerosol cans and others are powders or liquids which
you mix with water to produce a foam. To shampoo the
carpets, use a sponge or brush to apply the foam. Rub in
overlapping circles. Do not apply water Ð the best results are
obtained by keeping the carpet as dry as possible. Read the
shampoo instructions and follow them closely.The seat belts may be cleaned with mild soap and water or
with lukewarm water.
Use a cloth or sponge. As you are cleaning, check the belts for
excessive wear, fraying or cuts.
