CAUTION
■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 systems will not function correctly if different tires are fit-
ted 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.
■Active Torque Control 4WD system
●The AWD system of this vehicle is intended to ensure driving stability on
normal roads. It is not designed for use in demanding situations such as
rally driving.
●Take care when driving on slippery road surfaces.

Winter driving tips
Carry out the necessary preparations and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner appropri-
ate to the prevailing weather conditions.
■Pre-winter preparations
●Use fluids that are appropriate to the prevailing outside tem-
peratures.
• Engine oil
• Engine coolant
• Washer fluid
●Have a service technician inspect the level and specific grav-
ity of battery electrolyte.
●Have the vehicle fitted with four snow tires or purchase a set
of tire chains for the front tires.
Ensure that all tires are the same size and brand, and that chains
match the size of the tires.
■Before driving the vehicle
Perform the following according 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.

Selecting tire chains
Snow chains can be mounted on 16- and 17-inch tires. They cannot
be mounted on 18-inch tires. Use the correct snow chain size when
mounting the snow chains. Chain size is regulated for each tire size.
Side chain:
0.12 in. (3 mm) in diameter
0.39 in. (10 mm) in width
1.18 in. (30 mm) in length
Cross chain:
0.16 in. (4 mm) in diameter
0.55 in. (14 mm) in width
0.98 in. (25 mm) in length
Regulations on the use of snow chains
●Regulations regarding the use of tire chains vary according to loca-
tion and type of road. Always check local regulations before install-
ing chains.
●Install the chains on the front tires.
●Retighten the chains after driving 1/4 - 1/2 mile (0.5 - 1.0 km).
■When driving the vehicle
Accelerate the vehicle slowly and drive at a reduced speed suit-
able to road conditions.
■When parking the vehicle
Park the vehicle and move the shift lever to P (automatic trans-
mission), 1 or R (manual transmission) without setting the park-
ing brake. The parking brake may freeze up, preventing it from
being released. If necessary, block the wheels to prevent inad-
vertent sliding or creeping.

156 2-5. Driving information
■Snow chain installation (vehicles with 16-inch and 17-inch tires)
Observe the following precautions when installing and removing chains.
●Install and remove tire chains in a safe location.
●Install tire chains on the front tires only. Do not install tire chains on rear
tires.
●Install tire chains following the instructions provided in the accompanying
manual.
CAUTION
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in a loss of vehicle control and cause death or
serious injury.
●Use tires of the size specified for your vehicle.
●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.
■Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failing 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 turns and braking, as use of chains may adversely affect
vehicle handling.
●Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.

Trailer towing (1.8 L 4-cylinder [2ZR-FE] engine)
Toyota does not recommend towing a trailer with your vehicle.
Toyota also does not recommend the installation of a tow hitch or
the use of a tow hitch carrier for a wheelchair, scooter, bicycle, etc.
Your Toyota is not designed for trailer towing or for the use of tow
hitch mounted carriers.

When driving
■Before towing
●Ensure that your vehicle’s tires are properly inflated. (P. 360)
●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.

Trailer towing tips
Your vehicle will handle differently when towing a trailer. In order to
avoid accident, death or serious injury, keep the following in mind
when towing:
●Before starting out, check the trailer lights and the vehicle-trailer
connections. Recheck after driving a short distance.
●Practice turning, stopping and reversing with the trailer attached in
an area away from traffic until you become accustomed to the feel
of the vehicle.
NOTICE
■When installing a trailer hitch
●Use only the position recommended by your Toyota dealer. Do not install
the trailer hitch on the bumper; this may cause body damage.
●Do not use axle-mounted hitches, as they can cause damage to the axle
housing, wheel bearings, wheels or tires.
■Brakes
Toyota recommends trailers with brakes that conform to all applicable fed-
eral and state/provincial regulations.
■Safety chain
A safety chain must always be used between the towing vehicle and the
trailer. Leave sufficient slack in the chain for turns. The chain should cross
under the trailer tongue to prevent the tongue from dropping to the ground in
the case that it becomes damaged or separated. For the correct safety chain
installation procedure, ask your Toyota dealer.
■Do not directly splice trailer lights
Directly splicing trailer lights may damage your vehicle's electrical system
and cause a malfunction.

164 2-5. Driving information
●Reversing with a trailer attached is difficult and requires practice.
Grip the bottom of the steering wheel and move your hand to the
left to move the trailer to the left. Move your hand to the right to
move the trailer to right. (This is generally opposite to reversing
without a trailer attached.) Avoid sharp or prolonged turning. Have
someone guide you when reversing to reduce the risk of an acci-
dent.
●As stopping distance is increased when towing a trailer, vehicle-to-
vehicle distance should be increased. For each 10 mph (16 km/h)
of speed, allow at least one vehicle and trailer length.
●Avoid sudden braking as you may skid, resulting in jackknifing and
loss of control. This is especially true on wet or slippery surfaces.
●Avoid jerky starts or sudden acceleration.
●Avoid jerky steering and sharp turns, and slow down before mak-
ing turns.
●Note that when making a turn, the trailer wheels will be closer than
the vehicle wheels to the inside of the turn. Compensate by making
a larger than normal turning radius.
●Crosswinds and rough roads will adversely affect handling of your
vehicle and trailer, causing sway. Periodically check the rear to
prepare for being passed by large trucks or buses, which may
cause your vehicle and trailer to sway. If swaying occurs, firmly grip
the steering wheel, reduce speed immediately but gradually, and
steer straight ahead. Never increase speed. If you make no
extreme correction with the steering or brakes, your vehicle and
trailer will stabilize.
●Take care when passing other vehicles. Passing requires consider-
able distance. After passing a vehicle, do not forget the length of
your trailer, and be sure you have plenty of room before changing
lanes.

When driving
●To maintain engine braking efficiency and charging system perfor-
mance when using engine braking, do not use 5th gear (manual
transmission), or do not put the transmission in “D” (automatic
transmission).
●Due to the added load of the trailer, your vehicle's engine may
overheat on hot days (at temperatures over 85°F [30°C]) when
driving up a long or steep grade. If the engine coolant temperature
gauge indicates overheating, immediately turn off the air condition-
ing (if in use), pull your vehicle off the road and stop in a safe spot.
(P. 433)
●Always place wheel blocks under both the vehicle and the trailer
wheels when parking. Apply the parking brake firmly, and put the
transmission in P (automatic transmission) or in 1 or R (manual
transmission). Avoid parking on a slope, but if unavoidable, do so
only after performing the following:
Apply the brakes and keep them applied.
Have someone place wheel blocks under both the vehicle and
trailer wheels.
When the wheel blocks are in place, release the brakes slowly
until the blocks absorb the load.
Apply the parking brake firmly.
Shift into 1 or R (manual transmission) or P (automatic trans-
mission) and turn off the engine.

166 2-5. Driving information
●When restarting after parking on a slope:
With the transmission in the P position (automatic transmis-
sion) or the clutch pedal (manual transmission) depressed,
start the engine. On vehicles with an automatic transmission,
be sure to keep the brake pedal pressed.
Shift into a forward gear. If reversing, shift into the R position.
Release the parking brake (also brake pedal on vehicles with
an automatic transmission), and slowly pull or back away from
the wheel blocks. Stop and apply the brakes.
Have someone retrieve the blocks.
CAUTION
■To avoid an accident
●Do not exceed 45 mph (72 km/h) or posted towing speed limit, whichever
is lower. As instability (swaying) of the towing vehicle-trailer combination
increases as speed increases, exceeding 45 mph (72 km/h) may cause
loss of control.
●Slow down and downshift before descending steep or long downhill
grades. Do not make sudden downshifts while descending steep or long
downhill grades.
●Avoid holding the brake pedal down too long or applying the brakes too
frequently. This could cause the brakes to overheat and result in reduced
braking efficiency.
●Do not tow the vehicle with the compact spare tire installed.
