Maintenance and care
iQ_WE_74014E
CAUTION
Proper inflation is critical to save tire performance
Keep your tires properly inflated. Otherwise, the following conditions may
occur and result in an accident causing death or serious injury.
Excessive wear
Uneven wear
Poor handling
Possibility of blowouts resulting from overheated tires
Poor sealing of the tire bead
Wheel deformation and/or tire separation
A greater possibility of tire damage from road hazards
NOTICE
When inspecting and adjusting tire inflation pressure
Be sure to reinstall the tire valve caps.
Without the valve caps, dirt or moisture could get into the valve and cause
air leakage, which could result in an accident. If the caps have been lost,
replace them as soon as possible.

Wheels
If a wheel is bent, cracked or heavily corroded, it should be replaced.
Otherwise, the tire may separate from the wheel or cause loss of
handling control.
Wheel selection
When replacing wheels, care should be taken to ensure that
they are equivalent to those removed in load capacity, diameter,
rim width, and inset
*.
Replacement wheels are available at any authorized Toyota
dealer or repairer, or another duly qualified and equipped profes-
sional.
*: Conventionally referred to as “offset”.
Toyota does not recommend using:
Wheels of different sizes or types
Used wheels
Bent wheels that have been straightened
Aluminum wheel precautions (if equipped)
Use only Toyota wheel nuts and wrenches designed for use
with your aluminum wheels.
When rotating, repairing or changing your tires, check that the
wheel nuts are still tight after driving 1600 km (1000 miles).
Be careful not to damage the aluminum wheels when using
tire chains.
Use only Toyota genuine balance weights or equivalent and a
plastic or rubber hammer when balancing your wheels.

iQ_WE_74014E
Before performing emergency repair
Check the degree of the tire damage.
A tire should only be repaired
with the emergency tire puncture
repair kit if the damage is caused
by a nail or screw passing
through the tire tread.
• Do not remove the nail or
screw from the tire. Removing
the object may widen the
opening and prevent emer-
gency repair with the repair kit.
• To avoid sealant leakage,
move the vehicle until the area
of the puncture, if known, is
positioned at the top of the
tire.
In the following cases, the tire cannot be repaired with the emergency
tire puncture repair kit. Contact any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
When the tire is damaged due to driving without sufficient air pressure
When there are any cracks or damage at any location on the tire, such as
on the side wall, except the tread
When the tire is visibly separated from the wheel
When the cut or damage to the tread is 4 mm (0.16 in.) long or more
When the wheel is damaged
When two or more tires have been punctured
When more than 2 sharp objects such as nails or screws have passed
through the tread on a single tire
When the sealant has expired

418 5-2. Steps to take in an emergency
iQ_WE_74014ETaking precautions to avoid sudden braking, sudden accelera-
tion and sharp turns, drive carefully at under 80 km/h (50
mph) to the nearest authorized Toyota dealer or repairer, or
another duly qualified and equipped professional for tire repair
or replacement.
Emergency tire puncture repair kit
The sealant stored in the emergency tire puncture repair kit can be used
only once to temporarily repair a single tire. If the sealant has been used
and needs to be replaced, contact any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
The sealant can be used when the outside temperature is from -30°C
(-22°F) to 60°C (140°F).
The repair kit is exclusively designed for size and type of tires originally
installed on your vehicle. Do not use it for tires that a different size than
the original ones, or for any other purposes.
The sealant has a limited lifespan. The expiry date is shown on the bot-
tle. The sealant should be replaced before the expiry date. Contact any
authorized Toyota dealer or repairer, or another duly qualified and
equipped professional for replacement.
If the sealant gets on your clothes, it may stain.
If the sealant adheres to a wheel or the surface of the vehicle body, the
stain may not be removable if it is not cleaned at once. Immediately wipe
away the sealant with a wet cloth.
During operation of the repair kit, a loud operation noise is produced.
This does not indicate a malfunction.
Do not use to check or to adjust the tire pressure.

CAUTION
Do not drive the vehicle with a flat tire
Do not continue driving with a flat tire.
Driving even a short distance with a flat tire can damage the tire and the
wheel beyond repair.
Driving with a flat tire may cause a circumferential groove on the side wall. In
such a case, the tire may explode when using a repair kit.
Caution while driving
Store the repair kit in the luggage room.
Otherwise, the repair kit may fly out and break in events such as sudden
braking, and may cause an accident.
The repair kit is exclusively only for your vehicle.
Do not use repair kit on other vehicles, which could lead to an accident
causing death or serious injury.
Do not use repair kit for tires that are different size than the original ones,
or for any other purpose. If the tires have not been completely repaired, it
could lead to an accident causing death or serious injury.
Precautions for use of the sealant
Ingesting the sealant is hazardous to your health. If you ingest sealant,
consume as much water as possible, and then immediately consult a doc-
tor.
If sealant gets in eyes or adheres to skin, immediately wash it off with
water. If discomfort persists, consult a doctor.
When fixing the flat tire
Stop your vehicle in a safe and flat area.
Do not touch the wheels or the area around the brakes immediately after
the vehicle has been driven.
After the vehicle has been driven, the wheels and the area around the
brakes may be extremely hot. Touching these areas with hands, feet or
other body parts may result in burns.
Connect the valve and hose securely with the tire installed on the vehicle.
If the hose is not properly connected to the valve, air leakage may occur
as sealant may be sprayed out.

If the vehicle becomes stuck
Emergency hook
Carry out the following procedures if the tires spin or the vehicle
becomes stuck in mud, dirt, or snow.
Stop the engine. Set the parking brake and put the shift
lever in P (Multidrive) or N (manual transmission).
Remove the mud, snow, or sand from around the stuck tire.
Place wood, stones or some other material to help provide
traction under the tires.
Restart the engine.
Shift the shift lever to D or R (Multidrive) or 1 or R (manual
transmission) and carefully apply the accelerator to free the
vehicle.
Turn off the TRC and/or VSC systems if it is difficult to get out
because of TRC and/or VSC operation. (P. 225)
When your vehicle becomes stuck and
cannot move, the emergency hook is
used for another vehicle to pull your vehi-
cle out in an emergency.
Your vehicle is not designed to tow
another vehicle.
