Maintenance and care

It is normal for the brake fluid level to go down slightly as the brake pads wear out or
when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, there may be a serious problem.

CAUTION
■When connecting the battery terminal
Lower the lever into the locked position and ensure that the terminal is securely
fixed in place.
If the terminal is not securely fixed in place, it may come off while the vehicle is
being driven. This may cause the engine and electronic components to stop func-
tioning, resulting in an accident.
■Chemicals in the battery
A battery contains poisonous and corrosive sulfuric acid and may produce hydro-
gen gas which is flammable and explosive. To reduce the risk of death or serious
injury, take the following precautions while working on or near the battery:
●Do not cause sparks by touching the battery terminals with tools.
●Do not smoke or light a match near the battery.
●Avoid contact with eyes, skin and clothes.
●Never inhale or swallow electrolyte.
●Wear protective safety glasses when working near the battery.
●Keep children away from the battery.
■Where to safely charge the battery
Always charge the battery in an open area. Do not charge the battery in a garage or
closed room where there is insufficient ventilation.
■How to recharge the battery
Only perform a slow charge (5 A or less). The battery may explode if charged at a
quicker rate.

Maintenance and care
Initializing the tire pressure warning systemThe tire pressure warning system must be initialized when the tire infla-
tion pressure is changed (such as when changing traveling speed).
When the tire pressure warning system is initialized, the current tire infla-
tion pressure is set as the benchmark pressure.
■ How to initialize the tire pressure warning system
Park the vehicle in safe place and turn the ignition switch off.
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. ( P. 366)
Make sure to adjust the tire pressure to the specified cold tire inflation
pressure level. The tire pressure warning system will operate based on
this pressure level.
Turn the ignition switch to the “ON” position.
Press and hold the tire pressure
warning reset switch until the tire
pressure warning light flashes
slowly 3 times.
Wait for a few minutes with th e ignition switch in the “ON” posi-
tion and then turn the ignition switch off.

Registering ID codesThe tire pressure warning valve and transmitter is equipped with a unique
ID code. When replacing a tire pressu re warning valve and transmitter, it
is necessary to register the ID code. Ha ve the ID code registered by your
Lexus dealer.
■When to replace your vehicle’s tires
Tires should be replaced if:
●You have tire damage such as cuts, splits, cracks deep enough to expose the
fabric or bulges indicating internal damage
●A tire goes flat repeatedly or cannot be properly repaired due to the size or
location of a cut or other damage
If you are not sure, consult with your Lexus dealer.
■Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not registered,
the tire pressure warning system will not work properly. After driving for about 20
minutes, the tire pressure warning light fl ashes for 1 minute to indicate a system mal-
function.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even if they
have seldom or never been used or damage is not obvious.
■Routine tire inflation pressure checks
The tire pressure warning system does not replace routine tire inflation pressure
checks. Make sure to check tire inflation pressure as part of your routine of daily
vehicle checks.
■Tire rotation
It is not possible to rotate the tires, as each tire is designed only for its original posi-
tion on the vehicle.
