■Daytime running light system
●To make your vehicle more visible to other drivers, the headlights turn on
automatically whenever the engine is started and the parking brake is
released.
● Compared to turning on the headlights, the daytime running light system
offers greater durability and consumes less electricity, so it can help
improve fuel economy.

■Automatic cruise control cancelation
Cruise control will stop maintaining the vehicle speed in any of the following
situations.
●Actual vehicle speed falls more than approximately 10 mph (16 km/h)
below the preset vehicle speed.

When driving
To disable TRAC and/or VSC
If the vehicle gets stuck in fresh snow or mud, TRAC and VSC may
reduce power from the engine to the wheels. You may need to turn
the system off to enable you to rock the vehicle in order to free it.
■ Turning off TRAC
Quickly push and release the
button to turn off TRAC.
The “TRAC OFF” indicator light
should come on.
Push the button again to turn the
system back on.
■Turning off TRAC and VSC
Push and hold the button while
the vehicle is stopped to turn off
TRAC and VSC.
The “TRAC OFF” indicator light
and VSC OFF indicator light
should come on.
Push the button again to turn the
system back on.
■Automatic reactivation of TRAC and VSC
Turning the “ENGINE START STOP” switch or the engine switch OFF after
turning off the TRAC and VSC systems will automatically re-enable them.
■ Automatic TRAC reactivation
If only the TRAC system is turned off, the TRAC system will turn on when
vehicle speed increases.
■ Automatic TRAC and VSC reactivation
If the TRAC and VSC systems are turned off, the systems will not turn on
even when vehicle speed increases.

168 2-4. Using other driving systems
■Sounds and vibrations caused by ABS, brake assist, VSC and TRAC
●A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indi-
cate that a malfunction has occurred in any of these systems.
● Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after ABS is activated.
• The brake pedal may move down slightly after ABS is activated.
■ If the slip indicator light comes on
There is a malfunction in the TRAC and VSC systems. Contact your Toyota
dealer and have your Toyota inspected.
■ EPS operation sound
When the steering wheel operates, a motor sound (whirring sound) may be
heard.
This does not indicate a malfunction.
■ Reduced effectiveness of EPS
The effectiveness of EPS is reduced to prevent the system from overheating
when there is frequent steering input over an extended period of time. The
steering wheel may feel heavy as a result. Should this occur, refrain from
excessive steering input or stop the vehicle and turn the engine off. The sys-
tem should return to normal within 10 minutes.
CAUTION
■ABS does not operate effectively when
●Tires with inadequate gripping ability are used (such as excessively worn
tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on the wet or slick
road.

When driving
CAUTION
■Stopping distance when ABS is operating on the wet or slick roads
ABS is not designed to shorten the vehicle's stopping distance. Always
maintain a safe distance from the vehicle in front of you in the following situ-
ations.
●When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
● When driving over roads with potholes or uneven roads
■ TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRAC system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
■ When VSC is activated
The slip indicator light flashes and a warning buzzer sounds. Always drive
carefully. Reckless driving may cause an accident. Exercise particular care
when the indicator light flashes and a buzzer sounds.
■ When TRAC and VSC are off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are systems to ensure vehicle stability and driving force, do
not turn off TRAC and VSC unless necessary.
■ Replacing tires
Make sure that all tires are of the same size, brand, tread pattern and total
load capacity. In addition, make sure that the tires are inflated to the recom-
mended tire pressure level.
The ABS and VSC system will not function correctly if different tires are fitted
on the vehicle.
Contact your Toyota dealer for further information when replacing tires or
wheels.
■ Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause the system to malfunction.

180 2-5. Driving information
■Before towing
●Ensure that your vehicle’s tires are properly inflated. ( P. 378)
● Trailer tires should be inflated according to the trailer manufacturer's rec-
ommendation.
● All trailer lights must work in order to be legal.
● Confirm all lights work each time you connect them.
● Check that your vehicle remains level when a loaded or unloaded trailer
is hitched. Do not drive if the vehicle is not level, and check for improper
tongue load, overloading, worn suspension, or other possible causes.
● Make sure the trailer cargo is securely loaded.
● Check that your rear view mirrors conform to any federal, state/provincial
or local regulations. If they do not, install rear view mirrors appropriate for
towing purposes.
■ Break-in schedule
Toyota recommends that you do not use a new vehicle or a vehicle with any
new power train components (engine, transmission, differential, wheel bear-
ings, etc.) to tow a trailer for the first 500 miles (800 km) of driving.
■ Maintenance
●If you tow a trailer, your vehicle will require more frequent maintenance
due to the additional load. (See “Scheduled Maintenance Guide” or
“Owner's Manual Supplement”.)
● Retighten the fixing bolts of the towing ball and bracket after approxi-
mately 600 miles (1000 km) of trailer towing.

When driving
CAUTION
■
To avoid accident or injury
●Do not exceed the trailer hitch assembly weight, gross vehicle weight,
gross axle weight and trailer tongue load capacities.
● Never load more weight in the back than in the front of the trailer. About
60% of the load should be in the front half of the trailer, and the remaining
40% in the rear.
■ Hitches
●If you wish to install a trailer hitch, contact your Toyota dealer.
● Use only a hitch that conforms to the total trailer weight requirement.
● Follow the directions supplied by the hitch manufacturer.
● Lubricate the hitch ball with a light coat of grease.
● Remove the trailer hitch whenever you are not towing a trailer. After
removing the hitch, seal any mounting hole in the vehicle body to prevent
entry of any substances into the vehicle.
■ When towing a trailer
●If the gross trailer weight exceeds 1000 lb. (453 kg), trailer brakes are
required. Toyota recommends trailers wi th brakes that conform to all appli-
cable federal and state/provincial regulations.
● Never tap into your vehicle's hydraulic system, as this will lower the vehi-
cle's braking effectiveness.
● Never tow a trailer without using a safety chain securely attached to both
the trailer and the vehicle. If damage occurs to the coupling unit or hitch
ball, there is danger of the trailer wandering into another lane.
