Maintenance and care
■Checking fluid level
The brake fluid level should be between the “MAX” and “MIN” lines on the
tank.
■Adding fluid
Make sure to check the fluid type and prepare the necessary item.
■Brake fluid can absorb moisture from the air
Excess moisture in the brake fluid can cause a dangerous loss of braking efficiency. Use
only newly opened brake fluid.

ItemsClean funnel
WA R N I N G
■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, fl ush the affected area with clean water imme-
diately. 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 refil ling, there may be a serious problem.

When trouble arises
7-1. Essential information
If your vehicle has to be stopped in an emergency
Steadily step on the brake pedal with both feet and firmly depress it.
Do not pump the brake pedal repeatedly as this will increase the effort required to
slow the vehicle.
Shift the shift lever to N.
If the shift lever is shifted to N
After slowing down, stop the vehicle in a safe place by the road.
Stop the engine.
If the shift lever cannot be shifted to N
Keep depressing the brake pedal with both feet to reduce vehicle speed as
much as possible.
To stop the engine, press and hold
the engine switch for 2 consecutive
seconds or more, or press it briefly 3
times or more in succession.
Stop the vehicle in a safe place by the road.

■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 possi-
ble before turning off the engine.

When trouble arises
If your vehicle is transported by a flatbed truck, it should be tied down at the loca-
tions shown in the illustration.
If you use chains or cables to tie down your vehicle, the angles shaded in black
must be 45 .
Do not overly tighten the tie downs or the vehicle may be damaged.
If a tow truck is not available in an emergency, your vehicle may be temporarily
towed using cables or chains secured to the emergency towing eyelets. This
should only be attempted on hard surf aced roads for at most 50 miles (80 km)
at under 18 mph (30 km/h).
A driver must be in the vehicle to steer and operate the brakes. The vehicle’s
wheels, drive train, axles, steering an d brakes must be in good condition.
