If towing is necessary, we recommend
you to have it done by your Toyota
dealer or a commercial tow truck ser-
vice. In consultation with them, have
your vehicle towed using either (a) or
(b).
Only when you cannot receive a towing
service from a Toyota dealer or com-
mercial tow truck service, tow your ve-
hicle carefully in accordance with the
instructions given in ÐEmergency tow-
ingº on page 351 in this Section.
Proper equipment will help ensure that
your vehicle is not damaged while being
towed. Commercial operators are generally
aware of the state/provincial and local
laws pertaining to towing.
Your vehicle can be damaged if it is
towed incorrectly. Although most operators
know the correct procedure, it is possible
to make a mistake. To avoid damage to
your vehicle, make sure the following pre-
cautions are observed. If necessary, show
this page to the tow truck driver.TOWING PRECAUTIONS:
Use a safety chain system for all towing,
and abide by the state/provincial and local
laws. The wheels and axle on the ground
must be in good condition. If they are
damaged, use a towing dolly.

Generally, it is necessary to change
automatic transmission fluid only if your
vehicle is driven under one of the Special
Operating Conditions listed in your
Scheduled Maintenance Guideº or
Owner 's Manual Supplementº. When
changing the automatic transmission fluid,
use only Toyota Genuine ATF Type T- IVº
(ATF JWS3309 or NWS6500) to aid in
assuring optimum transaxle performance.
Notice: Using automatic transmission
fluid other than Toyota Genuine ATF
Type T- IVº may cause deterioration in
shift quality, locking up of your trans-
mission accompanied by vibration, and
ultimately damage the automatic trans-
mission of your vehicle.
Please contact your Toyota dealer for fur-
ther details.

If the engine is turned off when the over-
drive is off and restarted, the overdrive
will be on automatically.When the cruise control is being used,
even if you downshift the transmission by
pushing and releasing the overdrive
switch, engine braking will not be enabled
because the cruise control is not can-
celled.
For ways to decrease the vehicle speed,
see Cruise controlº on page 165 in this
Section.
(c) Normal driving
1. Start the engine as instructed in How
to start the engineº on page 318 in
Section 3. The transmission must be in
Pº or Nº.
2. With your foot holding down the brake
pedal, shift the selector lever to Dº.
When the lever is in the Dº position, the
automatic transmission system will select
the most suitable gear for running condi-
tions such as normal cruising, hill climb-
ing, hard towing, etc.
Always turn the overdrive on for better
fuel economy and quieter driving. If the
engine coolant temperature is low, the
transmission will not shift into the over-
drive gear even with the overdrive on.
CAUTION
Never put your foot on the accelera-
tor pedal while shifting.
3. Release the parking brake and brake
pedal. Depress the accelerator pedal
slowly for smooth starting.
(d) Using engine braking

the transmission as follows:
Push the overdrive switch. The O/D
OFFº indicator light will come on and
the transmission will downshift to third
gear.
Shift into the 2º position. The trans-
mission will downshift to second gear
when the vehicle speed drops down to
or lower than the following speed, and
stronger engine braking will be en-
abled.

When the cruise control is being used,
even if you downshift the transmission by
pushing and releasing the overdrive
switch, engine braking is not enabled be-
cause the cruise control is not cancelled.
For ways to decrease the vehicle speed,
see Cruise controlº on page 165 in this
Section.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to spin or
skid.
(e) Using 2º and Lº positions
The 2º and Lº positions are used for
strong engine braking as described pre-
viously.
With the selector lever in 2º or Lº, you
can start the vehicle in motion as with the
lever in Dº.
With the selector lever in 2º, the vehicle
will start in first gear and automatically
shift to second gear.
With the selector lever in Lº, the trans-
mission is engaged in first gear.
NOTICE

Be careful not to over- rev the en-
gine. Watch the tachometer to keep
engine rpm from going into the red
zone. The approximate maximum al-
lowable speed for each position is
given below for your reference:
Two- wheel drive models
2º 123 km/h (76 mph). . . . . . . . .
Lº 69 km/h (43 mph). . . . . . . . . .
Four- wheel drive models

Lº 62 km/h (38 mph). . . . . . . . . .

Do not continue hill climbing or
hard towing for a long time in the
2º or Lº position. This may cause
severe automatic transmission dam-
age from overheating. To prevent
such damage, Dº position should
be used in hill climbing or hard
towing.
(f) Backing up
1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with

In the following cases, contact your Toyota
dealer:
The warning light does not come on
after the ignition key is turned to ONº.
The warning light remains on after the
ignition key is turned to ONº.
The warning light comes on while driv-
ing.
The TRAC OFFº indicator light will come
on when the VSCº warning light comes
on even if the TRAC OFFº switch is not
pushed.The traction control system automatical-
ly helps prevent the spinning of 4
wheels when the vehicle is started or
accelerated on slippery road surfaces.
When the ignition key is turned to ONº,
the system automatically turns on.CAUTION
Under certain slippery road condi-
tions, full traction of the vehicle and
power against 4 wheels cannot be
maintained, even though the traction
control system is in operation. Do not
drive the vehicle under any speed or
maneuvering conditions which may
cause the vehicle to lose traction
control. In situations where the road
surface is covered with ice or snow,
your vehicle should be fitted with
snow tires or tire chains. Always
drive at an appropriate and cautious
speed for the present road condi-
tions.
NORMAL DRIVING MODE
Leave the system on during the ordi-
nary driving so that it can operate
when needed.
You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle
begins to move. This means that the trac-
tion control system is in the self- check
mode, but does not indicate a malfunction.
