3-3. Transaxle
If the selector lever will not move from P using the proper shift proce-
dure, continue to hold down the brake pedal.
Remove the shift-lock override
cover using a cloth-wrapped flat
head screwdriver.
Insert a screwdriver and push it
down.
Press and hold the lock-release
button.
Move the selector lever.
Take the vehicle to your Toyota d ealer to have the system checked.
The manual shift mode gives you the feel of driving a manual tran-
saxle vehicle by allowing you to operate the selector lever manually.
This allows you to control engine rpm and torque to the drive wheels
much like a manual transaxle when more control is desired.
To change to manual shift mode,
shift the lever from D to M.
To return to automatic shift mode, shift the lever from M to D.

3-6. ABS/TCS/DSC
Traction Control System (TCS)
The warning light turns on when the system has a malfunction.
Refer to Warning Lights on P. 157.
To turn off the TCS, press the DSC OFF switch ( →P. 197).
The Traction Control System (TCS) enhances traction and safety
by controlling engine torque and braking. When the TCS detects
driving wheel slippage, it lowers engine torque and operates the
brakes to prevent loss of traction.
This means that on a slick surface, the engine adjusts automati-
cally to provide optimum power to the drive wheels, limiting
wheel spin and loss of traction.
WARNING
■ Do not rely on the Traction Control System (TCS) as a substitute for
safe driving
The Traction Control System (TCS) cannot compensate for unsafe and
reckless driving, excessive speed, tailgating (following another vehicle too
closely), and hydroplaning (reduced tire friction and road contact because
of water on the road surface). You can still have an accident.
■ Use snow tires or tire chains and drive at reduced speeds when roads
are covered with ice and/or snow
Driving without proper traction devices on snow and/or ice-covered roads is
dangerous. The Traction Control System (TCS) alone cannot provide ade-
quate traction and you could still have an accident.

3-6. ABS/TCS/DSC
Dynamic Stability Control (DSC)
DSC operation is possible at speeds greater than 12 mph (20 km/h).
The warning light turns on when the system has a malfunction.
Refer to Warning Lights on P. 157.
The Dynamic Stability Control (DSC) automatically controls
braking and engine torque in conjunction with systems such as
ABS and TCS to help control side slip when driving on slippery
surfaces, or during sudden or e vasive maneuvering, enhancing
vehicle safety.
Refer to ABS (→ P. 193) and TCS ( →P. 194).
WARNING
■Do not rely on the Dynamic Stabilit y Control as a substitute for safe
driving
The Dynamic Stability Control (DSC) cannot compensate for unsafe and
reckless driving, excessive speed, tailgating (following another vehicle too
closely), and hydroplaning (reduced tire friction and road contact because
of water on the road surface). You can still have an accident.
NOTICE
●The DSC may not operate correctly unless the following are observed:
• Use tires of the correct size specif ied for your Toyota on all four wheels.
• Use tires of the same manufacturer, brand and tread pattern on all four wheels.
• Do not mix worn tires.
● The DSC may not operate correctly when tire chains are used or a tempo-
rary spare tire is installed because the tire diameter changes.

If your vehicle has Toyota optional antitheft wheel lug nuts, one on
each wheel will lock the tires and you must use a special key to unlock
them. This key will attach to the lug wrench. Register them with the
lock manufacturer by filling out the card provided in the glove com-
partment and mailing it in the ac companying envelope. If you lose this
key, consult your Toyota dealer or use the lock manufacturer’s order
form, which is with the registration card.
Accessory wheel locks cannot be used on steel wheels. This includes
situations when the spare tire is inst alled. If the spare tire is installed,
one of the original lug nuts (which should still be in the vehicle) must
be installed in place of the wheel lock.

Special key
■To remove an antitheft lug nutObtain the special key for the antitheft lug nut.
Place the special key on top of t he antitheft lug nut, and be sure
to hold the key square to it. If you hold the key at an angle, you
may damage both key and nut. Do not use a power impact
wrench.
Place the lug wrench on top of the key and apply pressure. Turn
the wrench counterclockwise.

If Trouble Arises
Remove dirt and grime from the
mounting surfaces of the wheel
and hub, including the hub
bolts, with a cloth.
Mount the spare tire.
Install the lug nuts with the bev-
eled edge inward; tighten them
by hand.
Turn the lug wrench counterclockwise and lower the vehicle.
Use the lug wrench to tighten
the nuts in the order shown.
If you are unsure of how tight the nuts should be, have them
inspected at your Toyota dealer.

WARNING
■Make sure the mounting surfaces of the wheel, hub and lug nuts
are clean before changing or replacing tires
When changing or replacing a tire, not removing dirt and grime from the
mounting surfaces of the wheel, hub and hub bolts is dangerous. The
lug nuts could loosen while driving and cause the tire to come off, result-
ing in an accident.
■Do not apply oil or grease to lug nuts and bolts and do not tighten
the lug nuts beyond the recommended tightening torque
Applying oil or grease to lug nuts and bolts is dangerous. The lug nuts
could loosen while driving and cause the tire to come off, resulting in an
accident. In addition, lug nuts and bolts could be damaged if tightened
more than necessary.
■Always securely and correctly tighten the lug nuts
Improperly or loosely tightened lug nuts are dangerous. The wheel
could wobble or come off. This could result in loss of vehicle control and
cause a serious accident.
■Be sure to reinstall the same nuts you removed or replace them
with metric nuts of the same configuration
Because the wheel studs and lug nuts on your Toyota have metric
threads, using a non-metric nut is dangerous. On a metric stud, it would
not secure the wheel and would damage the stud, which could cause
the wheel to slip off and cause an accident.
■Do not drive with any tires that have incorrect air pressure
Driving on tires with incorrect air pressure is dangerous. Tires with
incorrect pressure could affect handling and result in an accident. When
you check the regular tires’ air pressure, check the spare tire, too.
