2-8. Driving Tips
■Use snow tires on all four wheels
Do not go faster than 75 mph (120 km/h) while driving with snow
tires. Inflate snow tires 30 kPa (0.3 kgf/cm
2, 4.3 psi) more than rec-
ommended on the tire pressure label (driver’s door frame), but
never more than the maximum cold-tire pressure shown on the
tires.
The vehicle is originally equipped with all season radials designed
to be used all year around. In so me extreme climates you may find
it necessary to replace them with snow tires during the winter
months to further improve traction on snow and ice covered roads.
Check local regulations before using tire chains.
Install the chains on the front tires only.
Do not use chains on the rear tires.
Please consult your Toyota dealer.
■Installing the chains If your vehicle is equipped with wheel covers remove them, oth-
erwise the chain bands will scratch them.
Secure the chains on the front tires as tightly as possible.
Always follow the chain manufacturer’s instructions.
Retighten the chains after driv ing 1/4—1/2 mile (1/2—1 km).
If your vehicle is equipped with the tire pressure monitoring system, the
system may not function correctly when using tire chains.
Snow Tires
WARNING
■Use only the same size and type tires (snow, radial, or non-radial)
on all four wheels
Using tires different in size or type is dangerous. Your vehicle’s handling
could be greatly affected and result in an accident.
NOTICE
Check local regulations before using studded tires.

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.

When Driving
If the Smart City Brake Support
(SCBS) is operating, the indicator
light (red) flashes.
WARNING
■Do not modify the suspension
If the vehicle height or inclination is changed, the system will not be able to
correctly detect vehicles ahead. This will result in the Smart City Brake Sup-
port (SCBS) system not operating norma lly or mistakenly operating, which
could cause a serious accident.
■ Turn off the Smart City Brake Support (SCBS) when the vehicle is run-
ning on a chassis roller or being towed
Turn off the Smart City Brake Support (SCBS) system to prevent mistaken
operation when the vehicle is running on a chassis roller or being towed.
Refer to Stopping The Smart City Brake Support (SCBS) System Operation
on P. 210.
NOTICE
●When driving off-road in areas where there is grass or forage, it is recom-
mended that the Smart City Brake Support (SCBS) system be turned off.
● Always use tires for all wheels that are of the specified size, and the same
manufacturer, brand, and tread pattern. In addition, do not use tires with
significantly different wear patterns on the same vehicle as the Smart City
Brake Support (SCBS) system may not operate normally.

2193-12. Tire Pressure Monitoring System
3
When Driving
Because this system detects slight ch anges in tire conditions, the timing
of the warning may be faster or slower in the following cases:
●The size, manufacturer, or the type of tires is different from the specifica-
tion.
●The size, manufacturer, or the type of a tire is different from the others,
or the level of tire wear is excessively different between them.
●A run-flat tire, studless tire, snow tire, or tire chains are used.
●An emergency tire is used (The tire pressure monitoring system warning
light may flash and then continue illuminating).
●A tire is repaired using the emergency flat tire repair kit.
●The tire pressure is excessively hi gher than the specified pressure, or
the tire pressure is suddenly lowered for some reason such as a tire
burst during driving.
●The vehicle speed is lower than about 9.3 mph (15 km/h) (including
when the vehicle is stopped), or t he drive period is shorter than 5 min-
utes.
●The vehicle is driven on an extremely rough road or a slippery, icy road.
●Hard steering and rapid acceleration/deceleration are repeated such as
during aggressive driving on a winding road.
●Load on the vehicle is applied to a tire such as by loading heavy luggage
to one side of the vehicle.
●System initialization has not been im plemented with the specified tire
pressure.

3-12. Tire Pressure Monitoring System
NOTICE
●Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation pressure
label. (If your vehicle has tires of a different size than the size indicated
on the vehicle placard or tire inflation pressure label, you should deter-
mine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires is significantly under-
inflated. Accordingly, when the low tire pressure telltale illuminates,
you should stop and check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to tire failure. Under-infla-
tion also reduces fuel efficiency and tire tread life, and may affect the
vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire mainte-
nance, and it is th e driver’s responsibility to maintain correct tire pres-
sure, even if under-inflation has not reached the level to trigger
illumination of the TPMS lo w tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indica-
tor to indicate when the system is not operating properly.
The TPMS malfunction indicator is combined with the low tire pressure
telltale. When the system detects a malfunction, the telltale will flash
for approximately one minute and then remain continuously illumi-
nated. This sequence will continue upon subsequent vehicle start-ups
as long as the malfunction exists. When the malfunction indicator is
illuminated, the system ma y not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may occur for a variety of
reasons, including the installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to continue to function prop-
erly.
●To avoid false readings, the system samples for a little while before
indicating a problem. As a result it will not instantaneo usly register a
rapid tire deflation or blow out.

Maintenance and Care
Tires
Inspect all tire pressures monthly (including the spare) when the tires
are cold. Maintain recommended pressures for the best ride, han-
dling, and minimum tire wear.
Refer to the spec ification charts
(→P. 5 5 8).
With tire pressure monitoring system:
After adjusting the tire pressure, init ialization of the tire pressure mon-
itoring system is necessary to make the system operate normally.
Refer to Tire Pressure Monitoring System Initialization on P. 221.
For reasons of proper performance, safety, and better fuel econ-
omy, always maintain recommended tire inflation pressures and
stay within the recommended load limits and weight distribu-
tion.
WARNING
■Using Different Tire Types
Driving your vehicle with different ty pes of tires is dangerous. It could
cause poor handling and poor braking; leading to loss of control.
Except for the limited use of the temporary spare tire, use only the same
type tires (radial, bias-belted, bias-type) on all four wheels.
■Using Wrong-Sized Tires
Using any other tire size than what is specified for the vehicle (→P. 558)
is dangerous. It could seriously affect ride, handling, ground clearance,
tire clearance, and speedometer ca libration. This could cause you to
have an accident. Use only tires that are the correct size specified for
the vehicle.

If Trouble Arises
Changing a Flat Tire
Park on a level surface off the right-of-way and firmly set the park-
ing brake.
Put a vehicle with an automatic transaxle in Park (P), a manual
transaxle in Reverse (R) or 1, and turn off the engine.
Turn on the hazard warning flasher.
Have everyone get out of the vehicle and away from the vehicle
and traffic.
Remove the jack, tool, and spare tire ( →P. 477).
Block the wheel diagonally
opposite the flat tire. When
blocking a wheel, place a tire
block both in front and behind
the tire.
When blocking a tire, use rocks
or wood blocks of sufficient size if
possible to hold the tire in place.
●If the following occurs wh ile driving, it could indicate a flat tire.
• Steering becomes difficult.
• The vehicle begins to vibrate excessively.
• The vehicle pulls in one direction.
●Make sure the jack is well lubricated before using it.
If you have a flat tire, drive slowly to a level spot that is well off
the road and out of the way of traffic to change the tire.
Stopping in traffic or on the shoulder of a busy road is danger-
ous.
