In the following situations, the system may be malfunctioning. Have the vehi-
cle inspected by your Toyota dealer.

● The hill-start assist control ON indicator turns off and a buzzer sounds.
WARNING
■Hill-start assist control precautions
●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 control to hold the vehicle on an incline, as doing so may
lead to an accident.
● Do not stop the engine while hill-start assist control is operating, as hill-
start assist control will stop operating, possibly leading to an accident.

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
• Washer fluid
● Have a service technician inspect the condition of the battery.
● Have the vehicle fitted with four snow tires or purchase a set
of tire chains for the rear tires.
Make sure to install 4 tires that are of the specified size, and that all
4 tires are the same size, same maker, same brand and tread pat-
tern. Also, make sure to use tire chains that 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.
● Check for and remove any excess ice or snow that may have
accumulated on the exterior 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.

WARNING
■
Driving with tire chains
●Vehicles with an emergency tire puncture repair kit: When any of the tires
are punctured, you can seal the tire temporarily. However, do not use the
tire chain on a sealed tire. If any of the rear tires are punctured although it
is required to use tire chains, contact any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
● 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 km/h (19 mph), whichever is lower.
• Avoid driving on bumpy road surfaces or over potholes.
• Avoid sudden acceleration, abrupt steering, sudden braking and shifting operations that cause sudden engine braking.
• Slow down sufficiently before entering a curve to ensure that vehicle con- trol is maintained.
Always use the utmost care when driving with tire chains - overconfidence
because you are driving with tire chains could easily lead to a serious acci-
dent.
NOTICE
■ Using the tire chains
Use only chains that are of the correct size for your tires so as not to damage
the vehicle body or suspension.
■ Repairing or replacing snow tires
Request repairs or replacement of snow tires from Toyota dealers or legiti-
mate tire retailers.
This is because the removal and attachment of snow tires affects the opera-
tion of the tire pressure warning valves and transmitters.
■ Fitting tire chains
The tire pressure warning valves and transmitters may not function correctly
when tire chains are fitted.

Ventilation and air conditioning odors
●To let fresh air in, set the air condi tioning system to the outside air mode.
● During use, various odors from inside and outside the vehicle may enter
into and accumulate in the air conditioning system. This may then cause
odor to be emitted from the vents.
● To reduce potential odors from occurring:
It is recommended that the air conditioning system be set to outside air
mode prior to turning the vehicle off.

WARNING
■To prevent the windshield from fogging up
Do not set the air outlet selection dial to during cool air operation in
extremely humid weather. The difference between the temperature of the
outside air and that of the windshield can cause the outer surface of the
windshield to fog up, blocking your vision.
NOTICE
■To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the
engine is stopped.
