Driving
■When the rear differential is locked (vehicles with the rear differential
lock system)
The active traction control system is activated only when the vehicle speed is
less than 3 mph (6 km/h).
■ Sounds and vibrations caused by the active traction control system
● A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indicate
that a malfunction has occurred in the system.
● Vibrations may be felt through the vehicle body and steering. It may occur
when the system is operating.
■ If the brake system overheats
The system will cease operation, a buzzer will sound to alert the driver. Stop
the vehicle in a safe place. (There is no problem with continuing normal driv-
ing.)
The system will be automatically restored after a short time.
WARNING
■The active traction control system m ay not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the active traction control system is operat\
ing.
Do not drive the vehicle in conditions where stability and power may be lost.

Maintenance and care
■Brake fluid can absorb moisture from the air
Excess moisture in the brake fluid can cause a dangerous loss of braking effi-
ciency. Use only newly opened brake fluid.
■
Fluid level
The fluid level should be within the appropriate range.
2TR-FE engine
Full (when cold)
Add fluid (when cold)
Full (when hot)
Add fluid (when hot)
Hot: Vehicle has been driven around 50 mph (80 km/h) for 20 minutes, or slightly longer in frigid temperatures. (Fluid
temperature, 104°F - 175°F [40°C - 80°C])
Cold: Engine has not been run for about 5 hours. (Room tem- perature, 32°F - 104°F [0°C - 40°C])
WARNING
■When filling the reservoir
Take care as brake fluid can harm your hands and eyes and damage
painted surfaces.
If fluid gets on your hands or in your eyes, flush the affected area with clean
water immediately.
If you still experience discomfort, see a doctor.
NOTICE
■If the fluid level is low or high
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.

5068-1. Essential information
WARNING
■If the engine has to be turned off while driving
● Power assist for the brakes and steering wheel will be lost, making the
brake pedal harder to depress and the steering wheel heavier to turn.
Decelerate as much as possible before turning off the engine.
● Vehicles without a smart key system:
Never attempt to remove the key, as doing so will lock the steering wheel.
