Avoid long engine idling. If you have
a long wait and you are not in traffic,
it is better to turn off the engine and
start again later.

Avoid engine lugging or over- rev-
ving. Use a gear position suitable for
the road on which you are travelling.

Avoid continuous speeding up and
slowing down. Stop- and- go driving
wastes fuel.

Avoid unnecessary stopping and
braking. Maintain a steady pace. Try
to time the traffic signals so you only
need to stop as little as possible or
take advantage of through streets to
avoid traffic lights. Keep a proper dis-
tance from other vehicles to avoid sud-
den braking. This will also reduce wear
on your brakes.

Avoid heavy traffic or traffic jams
whenever possible.

Do not rest your foot on the brake
pedal. This causes premature wear,
overheating and poor fuel economy.

Maintain a moderate speed on high-
ways. The faster you drive, the greater
the fuel consumption. By reducing your
speed, you will cut down on fuel con-
sumption.

Keep the front wheels in proper
alignment. Avoid hitting the curb and
slow down on rough roads. Improper
alignment not only causes faster tire
wear but also puts an extra load on
the engine, which, in turn, wastes fuel.

Keep the bottom of your vehicle free
from mud, etc. This not only lessens
weight but also helps prevent corro-
sion.

Keep your vehicle tuned- up and in
top shape. A dirty air cleaner, improp-
er valve clearance, dirty plugs, dirty oil
and grease,brakes not adjusted, etc. all
lower engine performance and contrib-
ute to poor fuel economy. For longer
life of all parts and lower operating
costs, keep all maintenance work on
schedule, and if you often drive under
severe conditions, see that your vehicle
receives more frequent maintenance.
(For scheduled maintenance informa-
tion, please refer to the Scheduled
Maintenance Guideº or Owner 's Manu-
al Supplementº.)
CAUTION
Never turn off the engine to coast
down hills. Your power steering and
brake booster will not function with-
out the engine running. Also, the
emission control system operates
properly only when the engine is run-
ning.

To equalize tire wear and help ex-
tend tire life, Toyota recommends
that you rotate your tires accord-
ing to the maintenance schedule.
(For scheduled maintenance infor-
mation, please refer to the Sched-
uled Maintenance Guideº or Own-
er's Manual Supplementº.)
However, the most appropriate tim-
ing for tire rotation may vary ac-
cording to your driving habits and
road surface conditions.
See If you have a flat tireº on page
337 in Section 4 for tire change proce-
dure.When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire pres-
sure, improper wheel alignment, out-
of- balance wheels, or severe braking.
Initial adjustment of the tire pres-
sure warning system is necessary
after you have rotated your tires.
See Tire pressure warning sys-
temº on page 161 in Section 1- 7.
WHEN TO USE SNOW TIRES OR
CHAINS
Snow tires or chains are recommended
when driving on snow or ice.
On wet or dry roads, conventional tires
provide better traction than snow tires.
SNOW TIRE SELECTION
If you need snow tires, select tires of
the same size, construction and load
capacity as the originally installed tires.
Also, on four- wheel drive models, all
the tires must be the same brand and
have the same tread patterns.
Do not use tires other than those men-
tioned above. Do not install studded tires
without first checking local regulations for
possible restrictions.
CAUTION
Observe the following instructions.
Otherwise, an accident may occur re-
sulting in death or serious injuries.

Do not use snow tires other than
the manufacturer 's recommended si-
ze, as this may cause dangerous
handling characteristics resulting in
loss of control.

1 Inspect the fitting of the front fender and hood, etc., before welding, since this affects the appearance of the
finish.
2 Make sure each measurment is corect, as this parts affects the front wheel alignment. BP-18
INSTALLATION

Temporarily install the new parts and measure each part of the new parts in accordance with the body dimension
diagram. (See the body dimension diagram)

Inspect the fitting of the related parts around the new parts before welding. This affects the appearance of the
finish.

After welding, apply the polyurethane foam to the corresponding parts.

After welding, apply body sealer and under-coating to the corresponding parts.

After applying the top coat layer, apply anti-rust agent to the inside of the necked section structural weld spots.

HANDLING PRECAUTIONS ON RELATED COMPONENTS
1. BRAKE SYSTEM
The brake system is one of the most important safety components. Always follow the directions and
notes given in brake (32) section of the repair manual for the relevant model when handling brake system
parts.
NOTICE: When repairing the brake master cylinder or TRAC system, bleed the air out of the TRAC sys-
tem.
2. DRIVE TRAIN AND CHASSIS
The drive train and chassis are components that can have great effects on the running performance and
vibration resistance of the vehicle. After installing components in the sections listed in the table below,
perform alignments to ensure correct mounting angles and dimensions. Particularly accurate repair of
the body must also be done to ensure correct alignment.
HINT: Correct procedures and special tools are required for alignment. Always follow the directions giv-
en in the repair manual for the relevant model during alignment and section DI of this section.

3. COMPONENTS ADJACENT TO THE BODY PANELS
Various types of component parts are mounted directly on or adjacently to the body panels. Strictly ob-
serve the following precautions to prevent damaging these components and the body panels during han-
dling.

Before repairing the body panels, remove their components or apply protective covers over the com-
ponents.

Before prying components off using a screwdriver or a scraper, etc., attach protective tape to the tool
tip or blade to prevent damaging the components and the body paint.

Before removing components from the outer surface of the body, attach protective tape to the body to
ensure no damage to painted areas.
HINT: Apply touch-up paint to any damaged paint surfaces.

Before drilling or cutting sections, make sure that there are no wires, etc. on the reverse side.
4. ECU (ELECTRONIC CONTROL UNIT)
Many ECUs are mounted in this vehicle.
Take the following precautions during body repair to prevent damage to the ECUs.

Before starting electric welding operations, disconnect the negative (-) terminal cable from the bat-
tery.
When the negative (-) terminal cable is disconnected from the battery, memory of the clock and audio
systems will be cancelled. So before starting work, make a record of the contents memorized by each
memory system. Then when work is finished, reset the clock and audio systems as before.
When the vehicle has tilt and telescopic steering, power seat and outside rear view mirror, which are
all equipped with memory function, it is not possible to make a record of the memory contents.
So when the operation is finished, it will be necessary to explain this fact to the customer, and request
the customer to adjust the features and reset the memory.

Do not expose the ECUs to ambient temperatures above 80C (176F).
NOTICE: If it is possible the ambient temperature may reach 80C (176F) or more, remove the ECUs
from the vehicle before starting work.

Be careful not to drop the ECUs and not to apply physical shocks to them.
