• Turn the power switch off.

■

Installing towing eyelets to 

the vehicle

Make sure that towing eyelets are 

installed securely.

If not securely installed, towing 

eyelets may come loose during 

towing.

NOTICE

■

To prevent damage to the 

vehicle when towing using a 

wheel-lift type truck

●

Do not tow the vehicle from the 

rear when the power switch is 

off. The steering lock mecha-

nism is not strong enough to 

hold the front wheels straight.

●

When raising the vehicle, 

ensure adequate ground clear-

ance for towing at the opposite 

end of the raised vehicle. With-

out adequate clearance, the 

vehicle could be damaged while 

being towed.

■

To prevent damage to the 

vehicle when towing with a 

sling-type truck

Do not tow with a sling-type truck, 

either from the front or rear.

Towing with a sling-type truck

Do not tow with a sling-type truck to 

prevent body damage.

When using a flat-bed truck to 
transport the vehicle, use tire 
strapping belts. Refer to the 
owner’s manual of the flat-bed 
truck for the tire strapping 
method.
In order to suppress vehicle 
movement during transporta-
tion, 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 18 mph (30 
km/h).
A driver must be in 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 eye-
let must be installed to your 
vehicle. Install the towing eyelet 
using the following procedure.

8-2. Steps to take in an emergency

WARNING

■

When the electric power 

steering system warning light 

comes on

When the light comes on yellow, 

the assist to the power steering is 

restricted. When the light comes 

on red, the assist to the power 

steering is lost and handling oper-

ations of the steering wheel 

become extremely heavy.

When steering wheel operations 

are heavier than usual, grip the 

steering wheel firmly and operate 

it using more force than usual.

■

If the tire pressure warning 

light comes on

Be sure to observe the following 

precautions.

Failure to do so could cause a 

loss of vehicle control and result 

in death or serious injury.

●

Check and adjust the tire infla-

tion pressure immediately.

●

If the tire pressure warning light 

comes on even after tire infla-

tion pressure adjustment, it is 

probable that you have a flat 

tire. Have the flat tire replaced 

by the nearest Toyota dealer.

●

Avoid abrupt maneuvering and 

braking.

If the vehicle tires deteriorate, 

you could lose control of the 

steering wheel or the brakes.

■

If a blowout or sudden air 

leakage should occur

The tire pressure warning system 

may not activate immediately.

■

Maintenance of the tires

Each tire, including the spare (if 

provided), should be checked 

monthly when cold and inflated to 

the inflation pressure recom-

mended by the vehicle manufac-

turer on the vehicle placard or tire 

inflation pressure label (tire and 

load information label). (If your 

vehicle has tires of a different size 

than the size indicated on the 

vehicle placard or tire inflation 

pressure label [tire and load infor-

mation label], you should deter-

mine the proper tire inflation 

pressure for those tires.)

As an added safety feature, your 

vehicle has been equipped with a 

tire pressure monitoring system 

(TPMS-tire pressure warning sys-

tem) that illuminates a low tire 

pressure telltale (tire pressure 

warning light) when one or more 

of your tires is significantly under-

inflated. Accordingly, when the 

low tire pressure telltale (tire pres-

sure warning light) illuminates, 

you should stop and check your 

tires as soon as possible, and 

inflate them to the proper pres-

sure. Driving on a significantly 

under-inflated tire causes the tire 

to overheat and can lead to tire 

failure. Under-inflation also 

reduces fuel efficiency and tire 

tread life, and may affect the vehi-

cle’s handling and stopping ability.

Please note that the TPMS (tire 

pressure warning system) is not a 

substitute for proper tire mainte-

nance, and it is the driver’s 

responsibility to maintain correct 

tire pressure, even if under-infla-

tion has not reached the level to 

trigger illumination of the TPMS 

low tire pressure telltale (tire pres-

sure warning light).

equipped with a TPMS (tire pres-

sure warning system) malfunc-

tion indicator to indicate when the 

system is not operating properly. 

The TPMS (tire pressure warning 

system) malfunction indicator is 

combined with the low tire pres-

sure telltale (tire pressure warning 

light). When the system detects a 

malfunction, the telltale will flash 

for approximately one minute and 

then remain continuously illumi-

nated. This sequence will con-

tinue upon subsequent vehicle 

start-ups as long as the malfunc-

tion exists. When the malfunction 

indicator is illuminated, the sys-

tem may not be able to detect or 

signal low tire pressure as 

intended.

TPMS (tire pressure warning sys-

tem) malfunctions may occur for a 

variety of reasons, including the 

installation of replacement or 

alternate tires or wheels on the 

vehicle that prevent the TPMS 

(tire pressure warning system) 

from functioning properly. Always 

check the TPMS (tire pressure 

warning system) malfunction tell-

tale after replacing one or more 

tires or wheels on your vehicle to 

ensure that the replacement or 

alternate tires and wheels allow 

the TPMS (tire pressure warning 

system) to continue to function 

properly.

NOTICE

■

To ensure the tire pressure 

warning system operates 

properly

Do not install tires with different 

specifications or makers, as the 

tire pressure warning system may 

not operate properly.

If a warning message 

is displayed

The multi-information dis-
play shows warnings for 
system malfunctions and 
incorrectly performed oper-
ations, and messages that 
indicate a need for mainte-
nance. When a message is 
displayed, perform the 
appropriate corrective 
action for the message.

If a warning message is dis-
played again after the 
appropriate actions have 
been performed, contact 
your Toyota dealer.

Additionally, if a warning 
light comes on or flashes at 
the same time that a warn-
ing message is displayed, 
take the appropriate correc-
tive action for the warning 
light. (
