NOTICE
■If the fuel filter warning light comes on (diesel engine only)
Never drive the vehicle with the warning light on. Continued driving with
water accumulated in the fuel filter will damage the fuel injection pump.
■ When the DPF system warning light comes on (diesel engine with a
DPF system)
If the DPF system warning light is left on without performing cleaning, after
an additional 100 to 300 km (62 to 187 miles), the malfunction indicator
lamp may come on. If this happens, have the vehicle inspected by any
authorized Toyota dealer or repairer, or another duly qualified and equipped
professional immediately.
■ To ensure the tire pressure warning system operates properly (vehi-
cles with a tire pressure warning system)
Do not install tires with different specifications or makers, as the tire pres-
sure warning system may not operate properly.

■The compact spare tire
● The compact spare tire is identified by the label “TEMPORARY USE ONLY”
on the tire sidewall.
Use the compact spare tire temporarily, and only in an emergency.
● Make sure to check the tire inflation pressure of the compact spare tire.
( P. 509)
■ After completing the tire change (vehicles with a tire pressure warning
system)
The tire pressure warning system must be reset. ( P. 375)
■ When using the spare tire (include compact spare tire) (vehicles with a
tire pressure warning system)
As the spare tire is not equipped with a tire pressure warning valve and trans-
mitter, low inflation pressure of the spare tire will not be indicated by the tire
pressure warning system. Also, if you r eplace a flat tire with the spare tire
after the tire pressure warning light comes on, the light remains on.
■ If you have a flat front tire on a road covered with snow or ice
Install the compact spare tire on one of the rear wheels of the vehicle. Per-
form the following steps and fit tire chains to the front tires:
Replace a rear tire with the compact spare tire.
Replace the flat front tire with the tire removed from the rear of the vehi-
cle.
Fit tire chains to the front tires.

If the tire inflation pressure is 130 kPa (1.3 kgf/cm2 or bar, 19 psi)
or higher, but less than the specified air pressure: Proceed to .
If the tire inflation pressure is the specified air pressure ( P. 509):
Proceed to .
Turn the compressor switch on to inflate the tire until the specified
air pressure is reached. Drive for about 5 km (3 miles) and then
perform .
Store the compressor in the luggage compartment.
Taking precautions to avoid sudden braking, sudden acceleration
and sharp turns, drive carefully at under 80 km/h (50 mph) to the
nearest authorized Toyota dealer or repairer, or another duly quali-
fied and equipped professional for tire repair or replacement.
■ If the tire is inflated to more than the specified air pressure
Check that the air pressure indicator shows the specified air pressure.
If the air pressure is under the designated pressure, turn the compressor
switch on again and repeat the inflation procedure until the specified air
pressure is reached.
■ After a tire is repaired with the emergency tire puncture repair kit
● The tire pressure warning valve and transmitter should be replaced.
● Even if the tire inflation pressure is at the recommended level, the tire pres-
sure warning light may come on/flash.
Press the button to let some air out.

WARNING
■Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam-
mable gas that may be emitted from the battery:
● Make sure each jumper cable is connected to the correct terminal and that
it is not unintentionally in contact with anything other than the intended ter-
minal.
● Do not allow the + and - clamps of the jumper cables to come into contact
with each other.
● Do not smoke, use matches, cigarette lighters or allow open flame near
the battery.
■ Battery precautions
The battery contains poisonous and corrosive acidic electrolyte, while
related parts contain lead and lead compounds. Observe the following pre-
cautions when handling the battery:
● When working with the battery, always wear safety glasses and take care
not to allow any battery fluids (acid) to come into contact with skin, clothing
or the vehicle body.
● Do not lean over the battery.
● In the event that battery fluid comes into contact with the skin or eyes,
immediately wash the affected area with water and seek medical attention.
Place a wet sponge or cloth over the affected area until medical attention
can be received.
● Always wash your hands after handling the battery support, terminals, and
other battery-related parts.
● Do not allow children near the battery.
■ To prevent damage to the vehicle
Do not pull- or push-start the vehicle as the three-way catalytic converter
(gasoline engine) or catalytic conv erter (diesel engine) may overheat and
become a fire hazard.
NOTICE
■ When handling jumper cables
When connecting the jumper cables, ensure that they do not become entan-
gled in the cooling fans or engine drive belt.

If your vehicle overheats
●The high engine coolant temperature warning light (P. 431)
comes on or flashes, or a loss of engine power is experienced. (For
example, the vehicle speed does not increase.)
● Steam comes out from under the hood.
Stop the vehicle in a safe place and turn off the air conditioning sys-
tem, and then stop the engine.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the engine has cooled down sufficiently, inspect the hoses and
radiator core (radiator) for any leaks.
If a large amount of coolant leaks, immediately contact any authorized Toy-
ota dealer or repairer, or another duly qualified and equipped professional.
The following may indicate that your vehicle is overheating:
