■Hill-start assist control does not operate effectively when
●Do not overly rely on hill-start assist
control. Hill-start assist control may not operate effectively on steep
inclines and roads covered with ice.
●Unlike the parking brake, hill-start
assist control is not intended to hold
the vehicle stationary for an extended period of time. Do not
attempt to use hill-start assist con -
trol to hold the vehicle on an incline, as doing so may lead to an acci-
dent.
■When the TRC/ABS/VSC/Trailer
Sway Control is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular
care when the indicat or light flashes.
■When the TRC/VSC/Trailer Sway Control systems are turned off

speed appropriate t o the road condi- tions. As these ar e the systems to
help ensure vehicl e stability and driv-
ing force, do not turn the TRC/VSC/Trailer Sway Control sys -
tems off unle ss necessary.
Trailer Sway Control is part of the VSC system and will not operate if
VSC is turned off or experiences a
malfunction.
■Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern
and total load capac ity. In addition,
make sure that the tires are inflated to the recommended tire inflation pres -
sure level.
The ABS, TRC and VSC/Trailer Sway Control systems will not function cor -
rectly if different ti res are installed on
the vehicle. Contact any authorized Toyota
retailer or Toyota a uthorized repairer,
or any reliable repairer for further information when replacing tires or
wheels.
■Handling of tires and the suspen -
sion
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may
cause a system to malfunction.
■Trailer Sway Control precaution
The Trailer Sway C ontrol system is not able to reduce tr ailer sway in all
situations. Depending on many fac -
tors such as the conditions of the
vehicle, trailer, road surface and driv - ing environment, the Trailer Sway
Control system may not be effective.
Refer to your traile r owner’s manual for information on how to tow your
trailer properly.

4465-6. Driving tips
Perform the following according to
the driving conditions:
 Do not try to forcibly open a win-
dow or move a wiper that is fro -
zen. 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 sno w that has accu-
mulated on the air inlet vents in
front of the windshield.
 Check for and remove any
excess ice or snow that may
have accumulated on the exte -
rior 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 veh icle slowly, keep
a safe distance between you and
the vehicle ahead, and drive at a
reduced speed suitable to road
conditions.
 Park the vehicle and move the
s hif t le ve r to P w itho u t se tt ing th e
parking brake. The parking brake
may freeze up, preventing it from
being released. If the vehicle is
parked without setting the park -
ing brake, make sure to block the
wheels.
Failure to do so may be danger -
ous because it may cause the
vehicle to move unexpectedly,
possibly leading to an accident.
When the parking brake is in automatic
mode, release the parking brake after
shifting the shift lever to P. ( →P.326)
If the vehicle is left parked with
the brakes damp in cold tem -
peratures, there is a possibility of
the brakes freezing.
 If the vehicle is parked without
setting the parking brake, con -
firm that the shift lever cannot be
moved out of P*.
*: The shift lever will be locked if it is
attempted to be shifted from P to any
other position with out depressing the
brake pedal. If the shift lever can be
shifted from P, t here may be a prob-
lem with the shift lock system. Have
the vehicle inspected by any autho -
rized Toyota retailer or Toyota autho -
rized repairer, or any reliable repairer
immediately.

When trouble arises
When using a flat-bed truck to
transport the vehicle, use tire strap -
ping belts. Refer to the owner’s
manual of the flat-bed truck for the
tire strapping method.
In order to supp ress vehicle move-
ment during transportation, set the
parking brake and turn the power
switch off.
If a tow truck is not available in an
emergency, your vehicle may be
temporarily towed using cables or
chains secured to the emergency
towing eyelets. This should only be
attempted on hard surfaced roads
for short distances at under 30
km/h (18 mph).
A driver must be i n the vehicle to
steer and operate the brakes. The
vehicle’s wheels, drive train, axles,
steering and brakes must be in
good condition.
To have your vehicle towed by
another vehicle, the towing eyelet
must be installed to your vehicle.
Install the towing eyelet using the
following procedure.
1 Take out the wheel nut wrench
and towing eyelet. ( →P.583,
594)
2 Using a flathead screwdriver,
remove eyelet cover ( ), and
then remove eyelet cover ( ).
To protect the bodywork, place a rag
between the screwdriver and the vehi - cle body as shown in the illustration.
3 Insert the towing eyelet into the
hole and tighten partially by
hand.
4 Tighten down the towing eyelet
securely using a wheel nut
wrench (if equipped) or hard
metal bar.
