Driving assist systems
When VSC and TRAC are operating
If the vehicle is in danger of slip-
ping or the front wheels spin, the
indicator flashes to indicate that
VSC/TRAC have been engaged.
To help enhance driving safety and performance, the following sys-
tems operate automatically in res ponse to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heavi ly when operating the vehicle.
■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface.
■Brake assist
Generates an increased level of braking force after the brake pedal is
depressed, when the system detects a panic stop situation.
■VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces.
■TRAC (Traction Control)
Maintains drive power and prevents the front wheels from spinning
when starting the vehicle or accelerating on slippery roads.
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel.

When driving
■When the “TRAC OFF” indicator light comes on even if the VSC OFF
switch has not been pressed
TRAC cannot be operated. Contact your Toyota dealer.
■ 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 is operated, a motor sound (whirring sound) may
be heard. This does not indicate a malfunction.
■ Reduced effectiveness of the EPS system
The effectiveness of the EPS system 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 EPS system 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
■Storage precautions
Observe the following precautions.
Failing to do so may result in death or serious injury.
●To prevent cargo and luggage from sliding forward during braking, do
not stack anything in the enlarged trunk. Keep cargo and luggage low,
as close to the floor as possible.
●Never allow anyone to ride in the enlarged trunk. It is not designed for
passengers. They should ride in their seats with their seat belts prop-
erly fastened. Otherwise, they are much more likely to suffer death or
serious bodily injury, in the event of sudden braking, sudden swerving
or an accident.
●Do not place cargo or luggage in or on the following locations as the
item may get under the clutch, brake or accelerator pedal and prevent
the pedals from being depressed properly, block the driver’s vision, or
hit the driver or passengers, causing an accident.
• Driver’s feet
• Front passenger or rear seats (when stacking items)
• Package tray
• Instrument panel
• Dashboard
●Secure all items in the occupant compartment, as they may shift and
injure someone during sudden braking, sudden swerving or an acci-
dent.
■Capacity and distribution
●Do not exceed the maximum axle weight rating or the total vehicle
weight rating.
●Even if the total load of occupant's weight and the cargo load is less
than the total load capacity, do not apply the load unevenly.
Improper loading may cause deterioration of steering or braking con-
trol which may cause death or serious injury.

Vehicle load limits
■Total load capacity and seating capacity
These details are also described on the tire and loading information
label. (P. 376)
CAUTION
■Overloading the vehicle
Do not overload the vehicle.
It may not only cause damage to the ti res, but also degrade steering and
braking ability, resulting in an accident.
Vehicle load limits include total load capacity, seating capacity,
trailer weight rating and cargo capacity.
■ Total load capacity: 825 lb. (370 kg)
Total load capacity means the combined weight of occupants, cargo
and luggage.
■Seating capacity: 5 occupants (Front 2, Rear 3)
Seating capacity means the maxi mum number of occupants whose
estimated average weight is 150 lb. (68 kg) per person.
■ Trailer weight rating
2.4 L 4-cylinder (2AZ-FE) engine: 1500 lb. (680 kg)
1.8 L 4-cylinder (2ZR-FE) engine: Toyota does not recommend
towing a trailer with your vehicle.
■ Cargo capacity
Cargo capacity may increase or decrease depending on the weight
and the number of occupants.

Trailer towing tipsYour vehicle will handle differently when towing a trailer. Help to avoid
an accident, death or serious injury, keep the following in mind when
towing:
● Speed limits for towing a trailer vary by state or province. Do not
exceed the posted towing speed limit.
● Toyota recommends that the vehicle-trailer speed limit is 65 mph
(104 km/h) on a flat, straight, dry road. Do not exceed this limit, the
posted towing speed limit or the speed limit for your trailer as set
forth in your trailer owner’s man ual, whichever is lowest. Instability
of the towing vehicle-trailer combin ation (trailer sway) increases as
speed increases. Exceeding speed limits may cause loss of con-
trol.
● Before starting out, check the trailer lights, tires and the vehicle-
trailer connections. Recheck after driving a short distance.
● Practice turning, stopping and reve rsing with the trailer attached in
an area away from traffic until you become accustomed to the feel
of the vehicle-trailer combination.
● 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 the 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 o ne vehicle and trailer length.
● Avoid sudden braking as you may skid, resulting in the trailer jack-
knifing and a loss of vehicle control. This is especially true on wet
or slippery surfaces.

When driving
●
Avoid jerky starts or sudden acceleration.
● Avoid jerky steering and sharp turns, and slow down before mak-
ing a turn.
● Note that when making a turn, th e trailer wheels will be closer than
the vehicle wheels to the inside of the turn. Compensate by making
a wider than normal turning radius.
● Slow down before making a turn, in cross winds, on wet or slippery
surfaces, etc.
Increasing vehicle speed can destabilize the trailer.
● 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 hav e plenty of room before changing
lanes.
● Automatic transmission:
To maintain engine braking efficiency and charging system perfor-
mance when using engine braking, do not put the transmission in
“D”. If in the S mode, the transmission shift gear position must be in
4 or lower.
● Manual transmission:
To maintain engine braking efficiency and charging system perfor-
mance when using engine braking, do not use fifth gear.
● Instability happens more frequently when descending steep or long
downhill grades. Before descending, slow down and downshift. Do
not make sudden downshifts while descending steep or long down-
hill 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.

■
If trailer sway occurs
One or more factors (crosswinds, passing vehicles, rough roads, etc.) can
adversely affect handling of your vehicle and trailer, causing instability.
●If trailer swaying occurs:
• Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer swaying by turning the steering wheel.
• Begin releasing the accelerator pedal immediately but very gradually to reduce speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle
and trailer should stabilize.
● After the trailer swaying has stopped:
• Stop in a safe place. Get all occupants out of the vehicle.
• Check the tires of the vehicle and the trailer.
• Check the load in the trailer.
Make sure the load has not shifted.
Make sure the tongue weight is appropriate, if possible.
• Check the load in the vehicle. Make sure the vehicle is not overloaded after occupants get in.
If you cannot find any problems, the speed at which trailer swaying occu\
rred
is beyond the limit of your particular vehicle-trailer combination.
Drive at a lower speed to prevent instability. Remember that swaying of the
towing vehicle-trailer increases as speed increases.
CAUTION
■ Trailer towing precautions
To tow a trailer safely, use extreme care and drive the vehicle in accordance
with the trailer’s characteristics and operating conditions. Failure to do so
could cause an accident resulting in death or serious injury. Vehicle stability
and braking performance are affected by trailer stability, brake setting and
performance, and the hitch. Your vehicle will handle differently when towing
a trailer.
