When driving
Driving assist systems
nSounds and vibrations caused by the ABS
l A sound may be hea
rd 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 this system.
l 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 the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
n EP
S operation sound
When the steering wheel operates, a motor sound (whirrin
g sound) may be
heard.
This does not indicate a malfunction.
n 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.
To help enhance driving safety a nd 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.
nABS (Anti-lock Brake System) (if equipped)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface.
nEPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel.

2-5. Driving information
Vehicle load limits
nTotal load capacity and seating capacity
These details are also described on the tire and loading information
label.(→P. 2 6 4
)
CAUTION
nOverloading 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,
towing capacity and cargo capacity.
n Total load capacity: 845 lb. (383 kg)
Total load capacity means the combined weight of occupants,
car

go and luggage.
n Se
ating capacity: 5 occupants (Front 2, Rear 3)
Seating capacity means the ma ximum n
umber of occupants
whose estimated average weight is 150 lb. (68 kg) per person.
Even if the number of occupants are within the seating capacity,
do no

t exceed the total load capacity.
n T
owing capacity (Canada): 700 lb. (318 kg)
Towing capacity means the maximum gross trailer weight (trailer
weigh
t plus its cargo weight) that your vehicle is able to tow.
n T
owing capacity (except Canada)
Toyota does not recommend towing a trailer with your vehicle.
n Cargo cap
acity
Cargo capacity may increase or decrease depending on the
weigh
t and the number of occupants.

170 2-5. Driving information
lReversing 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.
l As stopp
ing 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.
l A
void sudden braking as you may skid, resulting in jackknifing and
loss of control. This is especiall y true on wet or slippery surfaces.
l A
void jerky starts or sudden acceleration. Vehicles with a manual
transmission, prevent excessive clut ch slippage by keeping engine
rpm low and not racing the engine. Always start out in first gear.
l A
void jerky steering and sharp turns, and slow down before mak -
ing a turn.
l 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 larger than normal turning radius.
l Cr
osswinds 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 steeri ng or brakes, your vehicle and
trailer will stabilize.
l T
ake care when passing other v ehicles. Passing requires consider -
able distance. After passing a vehi cle
, do not forget the length of
your trailer, and be sure you have plenty of room before changing
lanes.

5-1. Essential information
If your vehicle needs to be towed
Before towing
The following may indicate a problem with your transmission. Contact
your Toyota dealer before towing.
lThe en
gine is running, but the vehicle will not move.
lThe
vehicle makes an abnormal sound.
Emergency towing
If a tow truck is not available, in an emergency your vehicle may be
temporarily towed using a cable or chain secured to the emergency
towing eyelet. This should only attempted on hard, surfaced roads for
short distances at low speeds.
A driver must be in the vehicle to steer and operate the brakes. The
ve
hicle’s wheels, drive train, axles, steering and brakes must be in
good condition.
Towing eyelet
If towing is necessary, we recommend having your vehicle towed by
your Toyota dealer or a commerci al towing service, using a lift-type
truck or a flat bed truck.

Use a safety chain system for all to wing, and abide by
all state/pro-
vincial and local laws.
If towing from the front, the vehic le's rear
wheels and axles must be
in good condition. (→P
. 300)
If they are damaged, use a towing dolly or flat bed truck.

298 5-1. Essential information
nEmergency towin g procedure
Release the parking brake.
Put the transmission in N.
Turn the engine switch to the ACC (engine off) or ON (engine run -
ning) position.
CAUTION
nCaution while towing
lUse extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which place excessive
stress on the emergency towing eyelet and the cables or chains.
l If the engine is not running, the power assist for the brakes and steering
will not function, making steering and braking more difficult.
NOTICE
nTo prevent causing serious dama ge to the transmission
(vehicles with an automatic transmission)
Never tow this vehicle from the rear with the front wheels on the ground.
This may cause serious damage to the transmission.
n When towing a vehicle without using a towing dolly
(vehicles with a manual transmission)
Do not tow with the key removed or in the LOCK position.

5-1. Essential information
Towing with a wheel lift-type truck from the rear
Vehicles with an automatic trans-
mission: Use a towing dolly
u

nder the front wheels.
Vehicles with a manual transmis -
sion: We recommend to use a
tow

ing dolly under the front
wheels.
When not using a towing dolly,
turn the engine switch to the ACC
position and shift the shift lever to
N.
NOTICE
n To prevent damaging the vehicle
When raising the vehicle, ensure adequate ground clearance for towing at
the opposite end of the raised vehicle. Without adequate clearance, the
vehicle could be damaged while being towed.
NOTICE
nTo prevent causing serious da mage to the transmission
(vehicles with an automatic transmission)
Never tow this vehicle from the rear with the front wheels on the ground.
n To prevent damaging the vehicle (vehicles with a manual transmission)
lDo not tow the vehicle with the key removed or in the LOCK position.
The steering lock mechanism is not strong enough to hold the front wheel
straight.
l When raising the vehicle, ensure adequate ground clearance for towing at
the opposite end of the raised vehicle. Without adequate clearance, the
vehicle could be damaged while being towed.
