7-1.Mainte nance a nd care
Working from top to bottom, lib-
erally apply water to the vehicle
body, wheel wells and underside
of the vehicle to remove any dirt
and dust.
 Wash the vehicle body using a
sponge or soft cloth, such as a
chamois.
 For hard-to-remove marks, use
car wash soap and rinse thor-
oughly with water.
 Wipe away any water.
 Wax the vehicle when the water-
proof coating deteriorates.
If water does not bead on a clean sur-
face, apply wax when the vehicle body
is cool.
■Self-restoring coat
The vehicle body has a self-restoring coating that is resistant to small surface scratches caused in a car wash, etc.
●The coating lasts for 5 to 8 years from when the vehicle is delivered from the
plant.
●The restoration time differs depending
on the depth of the scratch and out- side temperature. The restoration time may become shorter when the coating
is warmed by applying warm water.
●Deep scratches caused by keys,
coins, etc., cannot be restored.
●Do not use wax that contain abra- sives.
■Automatic car washes
●Before washing the vehicle:• Fold the mirrors
• Turn off the power back door (if equipped)
Start washing from the front of the vehi-
cle. Extend the mirrors before driving.
●Brushes used in automatic car washes may scratch the vehicle sur-face, parts (wheel, etc.) and harm
your vehicle’s paint.
●Rear spoiler (if equipped) may not be
washable in some automatic car washes. There may also be an increased risk of damage to vehicle.
●When the shift position needs to be held in N, refer to P.251.
■High pressure car washes
As water may enter the cabin, do not bring the nozzle tip near the gaps around the doors or perimeter of the
windows, or spray these areas continu- ously.
■Note for a smart entry & start sys-tem
●If the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. In that case, follow the following correction procedures to
wash the vehicle: • Place the key in a position 2 m (6 ft.) or more separate from the vehicle
while the vehicle is being washed. (Take care to ensure that the key is not stolen.)
• Set the electronic key to battery-sav- ing mode to disable the smart entry & start system ( P.204)
●If the electronic key is inside the vehi- cle and a door handle becomes wet
during a car wash, a buzzer may sound outside the vehicle and “Key Detected In Vehicle” may be shown

Maintenance and care
Rotate the tires in the order shown.
Front
To equalize tire wear and help extend
tire life, Toyota recommends that tire
rotation is carried out approximately
every 10000 km (6000 miles).
Do not fail to initialize the tire pressure
warning system after tire rotation.
■When rotating the tires
Make sure that the power switch is OFF. If the tires are rotated while the power
switch is in ON, the tire position informa- tion will not be updated. If this accidentally occurs, either turn the
power switch to OFF and then to ON, or initialize the tire pressure warning sys-tem after checking that the tire pressure
is properly adjusted.
Your vehicle is equipped with a tire
pressure warning system that uses
tire pressure warning valves and
WARNING
■When inspecting or replacing tires
Observe the following precautions to prevent accidents. Failure to do so may cause damage
to parts of the drivetrain as well as dangerous handling characteristics, which may lead to an accident result-
ing in death or serious injury.
●Do not mix tires of different makes,
models or tread patterns. Also, do not mix tires of remarkably different treadwear.
●Do not use tire sizes other than those recommended by Toyota.
●Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).
●Do not mix summer, all season and
snow tires.
●Do not use tires that have been
used on another vehicle. Do not use tires if you do not know how they were used previously.
●Do not tow anything if a tire that has been repaired using the emergency
tire puncture repair kit is installed. The load on the tire may cause unexpected damage to the tire.
NOTICE
■Driving on rough roads
Take particular care when driving on roads with loose surfaces or potholes. These conditions may cause losses in
tire inflation pressure, reducing the cushioning ability of the tires. In addi-tion, driving on rough roads may
cause damage to the tires them- selves, as well as the vehicle’s wheels and body.
■If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires
and/or wheels may be ruined.

■Repairing or replacing tires, wheels, tire pressure warning
valves, transmitters and tire valve caps
●When removing or fitting the
wheels, tires or the tire pressure warning valves and transmitters, contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer as the tire pressure warning valves
and transmitters may be damaged if not handled correctly.
●Make sure to install the tire valve caps. If the tire valve caps are not installed, water could enter the tire
pressure warning valves and the tire pressure warning valves could be bound.
●When replacing tire valve caps, do not use tire valve caps other than
those specified. The cap may become stuck.
■To avoid damage to the tire pres-sure warning valves and trans-mitters
When a tire is repaired with liquid sealants, the tire pressure warning valve and transmitter may not operate
properly. If a liquid sealant is used, contact any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer or other qualified ser- vice shop as soon as possible. After use of liquid sealant, make sure to
replace the tire pressure warning valve and transmitter when repairing or replacing the tire.

8-2. Steps to take in an emergency
■Stopping the EV system
Set the parking brake, shift the shift
position to P and press the power switch as you normally do when stopping the EV system.
■Electronic key battery
As the above procedure is a temporary measure, it is recommended that the electronic key battery be replaced
immediately when the battery is depleted. ( P.499)
■Alarm (if equipped)
Using the mechanical key to lock the
doors will not set the alarm system. If a door is unlocked using the mechani-cal key when the alarm system is set,
the alarm may be triggered. ( P. 7 7 )
■Changing power switch modes
Release the brake pedal and press the power switch in step 3 above.
The EV system does not start and modes will be changed each time the switch is pressed. ( P.246)
If you have a set of jumper (or
booster) cables and a second vehi-
cle with a 12-volt battery, you can
jump start your vehicle by following
the steps below.
1 Confirm that the electronic key
is being carried.
When connecting the jumper (or
booster) cables, depending on the situ- ation, the alarm may activate and the doors may lock. ( P.78)
2Open the hood (P.467).
3 Open the positive (+) battery ter-
minal cover.
While pressing on the claw, open the
If the 12-volt batter y is

When trouble arises
order from which they were con-
nected.
10 Close the positive (+) battery
terminal cover.
Once the EV system starts, have
the vehicle inspected at any autho-
rized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer as soon as possible.
■Starting the EV system when the 12-volt battery is discharged
The EV system cannot be started by push-starting.
■To prevent 12-volt battery dis-charge
●Turn off the headlights, the air condi-tioning system, the audio system, etc.
while the EV system is off.
●Turn off any unnecessary electrical
components when the vehicle is run- ning at a low speed for an extended period, such as in heavy traffic.
■Charging the 12-volt battery
The electricity stored in the 12-volt bat- tery will discharge gradually even when the vehicle is not in use, due to natural
discharge and the draining effects of certain electrical appliances. If the vehi-cle is left for a long time, the 12-volt bat-
tery may discharge, and the EV system may be unable to start. (The 12-volt bat-tery recharges automatically while the
EV system is operating.)
■When the 12-volt battery is removed or discharged
●Information stored in the ECU is cleared. When the 12-volt battery is depleted, have the vehicle inspected
at any authorized Toyota retailer or Toyota authorized repairer, or any reli-able repairer.
●In some cases, it may not be possible to unlock the doors using the smart
entry & start system when the 12-volt
battery is discharged. Use the wire-
less remote control or the mechanical key to lock or unlock the doors.
●The EV system may not start on the first attempt after the 12-volt battery has recharged but will start normally
after the second attempt. This is not a malfunction.
●The power switch mode is memorized by the vehicle. When the 12-volt bat-tery is reconnected, the system will
return to the mode it was in before the 12-volt battery was discharged. Before disconnecting the 12-volt bat-
tery, turn the power switch off. If you are unsure what mode the power switch was in before the 12-volt
battery discharged, be especially careful when reconnecting the 12-volt battery.
●If the 12-volt battery discharges, it may not be possible to shift the shift
position to other positions. In this case, the vehicle cannot be towed without lifting both front wheels
because the front wheels will be locked.
●The power back door (if equipped) must be initialized. ( P.198)
■When replacing the 12-volt battery
●Use a 12-volt battery that conforms to European regulations.
●Use a 12-volt battery that the case size is same as the previous one (LN1), 20 hour rate capacity (20HR) is
equivalent (45Ah) or greater, and per- formance rating (CCA) is equivalent (286A) or greater.
• If the sizes differ, the 12-volt battery cannot be properly secured.• If an improper 12-volt battery is used,
battery performance may decrease and the EV system may not be able to restart.
• If the 20 hour rate capacity is low, even if the time period where the vehi-cle is not used is a short time, the 12-
volt battery may discharge and EV system may not be able to start.
