CAUTION
■When using the rear view monitor system
The rear view monitor system is a supplemental device intended to assist
the driver when backing up. When backing up, be sure to visually check all
around the vehicle both directly and using the mirrors before proceeding.
Observe the following precautions to avoid an accident that could result in
death or serious injuries.
● Never depend on the rear view monitor system entirely when backing up.
The image and the position of the guide lines displayed on the screen may
differ from the actual state.
Use caution, just as you would when backing up any vehicle.
● Be sure to back up slowly, depressing the brake pedal to control vehicle
speed.
● The instructions given are only guide lines.
When and how much to turn the steering wheel will vary according to traf-
fic conditions, road surface conditions, vehicle condition, etc. when park-
ing. It is necessary to be fully aware of this before using the rear view
monitor system.
● When parking, be sure to check that the parking space will accommodate
your vehicle before maneuvering into it.
● Do not use the rear view monitor system in the following cases:
• On icy or slick road surfaces, or in snow
• When using tire chains or emergency tires
• When the tailgate is not closed completely
• On roads that are not flat or straight, such as curves or slopes.
● In low temperatures, the screen may darken or the image may become
faint. The image could distort when the vehicle is moving, or you may
become unable to see the image on the screen. Be sure to visually check
all around the vehicle both directly and using the mirrors before proceed-
ing.
● If the tire sizes are changed, the position of the fixed guide lines displayed
on the screen may change.
● The camera uses a special lens. The distances between objects and
pedestrians that appear in the image displayed on the screen will differ
from the actual distances. ( →P. 216)

2404-5. Using the driving support systems
■Reactivation of the TRAC/VSC/A-T RAC/Trailer Sway Control systems
Even after the TRAC/VSC/A-TRAC/Trailer Sway Control systems have been
turned off, turning the engine switch off and then on again will automatically
reactivate the TRAC/VSC/A-TRAC/Trailer Sway Control systems.
■ Reactivation of the TRAC system linked to vehicle speed
When only the TRAC system is turned off, the TRAC system will turn on
when vehicle speed increases. However, when both TRAC/VSC systems are
turned off, the systems will not turn on even when vehicle speed increases.
■ If the brake system overheats
TRAC or A-TRAC will cease operation, and the slip indicator will change from
flashing to being on continuously to alert the driver. Stop the vehicle in a safe
place. (There is no problem with continuing normal driving.)
■ Shifting to “4L”
VSC and Trailer Sway Control are automatically turned off.
CAUTION
■The ABS does not operate effectively when
● The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on wet or slick roads.
■ Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the
following situations:
● 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 surfaces
■ TRAC or A-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 or A-TRAC system is operating.
Drive the vehicle carefully in conditions where stability and power may be
lost.

Winter driving tips
●Use fluids that are appropriate to the prevailing outside tempera-
tures. • Engine oil
• Engine coolant
• Washer fluid
● Have a service technician ins pect the condition of the battery.
● Have the vehicle fitted with four snow tires or purchase a set of tire
chains for the rear tires.
Ensure that all tires are the same size and brand, and that chains match
the size of the tires.
Perform the following accordin g to the driving conditions:
● Do not try to forcibly open a window or move a wiper that is frozen.
Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to prevent it from freezing.
● To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
● Check for and remove any excess ice or snow that may have accu-
mulated on the exterior lights, vehicle’s roof, chassis, around the
tires or on the brakes.
● Remove any snow or mud from the bottom of your shoes before
getting in the vehicle.
Accelerate the vehicle slowly, keep a safe distance between you and
the vehicle ahead, and drive at a reduced speed suitable to road con-
ditions.
Carry out the necessary preparations and inspections before
driving the vehicle in winter. Al ways drive the vehicle in a man-
ner appropriate to the prevailing weather conditions.

Regulations regarding the use of tire chains vary depending on loca-
tion and type of road. Always check local regulations before installing
chains.
■ Tire chain installation
Observe the following precautions when installing and removing chains:
●Install and remove tire chains in a safe location.
● Install tire chains on the rear tires. Do not install tire chains on the front tires.
● Install tire chains on rear tires as tightly as possible. Retighten chai\
ns after
driving 1/4 ⎯ 1/2 mile (0.5 ⎯ 1.0 km).
● Install tire chains following the instructions provided with the tire ch\
ains.
Regulations on the use of tire chains
CAUTION
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or
serious injury.
● Use tires of the specified size.
● Maintain the recommended level of air pressure.
● Do not drive in excess of 75 mph (120 km/h), regardless of the type of
snow tires being used.
● Use snow tires on all, not just some wheels.
● 4WD models: Do not mix tires of different makes, models, tread patterns
or treadwear.
■ Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the vehicle being unable to be driven safely,
and may cause death or serious injury.
● Do not drive in excess of the speed limit specified for the tire chains being
used, or 30 mph (50 km/h), whichever is lower.
● Avoid driving on bumpy road surfaces or over potholes.
● Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden engine braking.
● Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.

2484-6. Driving tips
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow tires from Toyota dealers or legiti-
mate tire retailers.
This is because the removal and attachment of snow tires affects the opera-
tion of the tire pressure warning valves and transmitters.
■ Fitting tire chains
The tire pressure warning valves and transmitters may not function correctly
when tire chains are fitted.

4307-3. Do-it-yourself maintenance
■Tire types
●Summer tires
Summer tires are high-speed performance tires best suited to highway
driving under dry conditions. Since summer tires do not have the same
traction performance as snow tires, summer tires are inadequate for
driving on snow-covered or icy ro ads. For driving on snow-covered
roads or icy roads, the use of snow tires is recommended. When install-
ing snow tires, be sure to replace all four tires.
●All season tires
All season tires are designed to provide better traction in snow and to
be adequate for driving in most winter conditions as well as for use
year-round. All season tires, however, do not have adequate traction
performance compared with snow tires in heavy or loose snow. Also, all
season tires fall short in acceleration and handling performance com-
pared with summer tires in highway driving.
●Snow tires
For driving on snow-covered roads or icy roads, we recommend using
snow tires. If you need snow tires, select tires of the same size, con-
struction and load capacity as the or iginally installed tires. Since your
vehicle has radial tires as original equipment, make sure your snow
tires also have radial construction. Do not install studded tires without
first checking local regulations fo r possible restrictions. Snow tires
should be installed on all wheels. ( →P. 245)
■If the tread on snow tires wears down below 0.16 in. (4 mm)
The effectiveness of the tire s as snow tires is lost.
■Situations in which the tire pressure warning system may not oper-
ate properly
●In the following cases, the tire pr essure warning system may not operate
properly.
• If non-genuine Toyota wheels are used.
• A tire has been replaced with a tire that is not an OE (Original Equip- ment) tire.
• A tire has been replaced with a tire that is not of the specified size.
• Tire chains, etc., are equipped.
• An auxiliary-supported run- flat tire is equipped.
• If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on the vehicle, particularly around the wheels or wheel housings.
• If the tire inflation pressure is extremely higher than the specified
level.

4988-2. Steps to take in an emergency
Confirm it is not loose after
tightening:Push and pull the tire
Try rotating
Visually check to ensure tire is
not hung on surrounding parts.
If looseness or misassembly exists, repeat step and step .
Repeat step , any time the ti re is lowered or disturbed.
Stow the tools and jack securely.
■The temporary spare tire
●The temporary spare tire is identified by the label “TEMPORARY USE
ONLY” on the disc wheel.
Use the temporary spare tire temporarily, and only in an emergency.
●Make sure to check the tire inflation pressure of the temporary spare
tire. ( →P. 526)
■After completing the tire change
The tire pressure warning system must be reset. ( →P. 428)
■When reinstalling the wheel ornament (on some models)
→P. 4 3 8
■When using the temporary spare tire
As the temporary spare tire is not equipped with the tire pressure warning
valve and transmitter, low inflation pressure of the spare tire will not be
indicated by the tire pressure warning system. Also, if you replace the
temporary spare tire after the tire pressure warning light comes on, the
light remains on.
■If you have a flat rear tire on a road covered with snow or ice
Install the temporary spare tire on one of the front wheels of the vehicle.
Perform the following steps and fit tire chains to the rear tires:
Replace a front tire with the temporary spare tire.
Replace the flat rear tire with the tire removed from the front of the
vehicle.
Fit tire chains to the rear tires.
