Maintenance and care
CAUTION
■
When working on the engine compartment
●Take care because brake fluid can harm your hands or 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.
■ When working near the electric cooling fan or radiator grille
Be sure the engine switch is off.
With the engine switch on, the electric cooling fan may automatically start to
run if the air conditioning is on and/or the coolant temperature is high.
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.
NOTICE
■If you remove the air cleaner
Driving with the air cleaner removed may cause excessive engine wear due
to dirt in the air. Also a backfire could cause a fire in the engine compart-
ment.
■ If the brake fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious pro\
blem.

252 4-3. Do-it-yourself maintenance
CAUTION
■When raising your vehicle
Make sure to observe the following to reduce the possibility of death or\

● Stop the vehicle on level firm ground, firmly set the parking brake and put
the shift lever in P (automatic transmission) or R (manual transmission).
● Make sure to set the floor jack properly at the jack point.
Raising the vehicle with an improperly positioned floor jack will damage
the vehicle and may cause the vehicle to fall off the floor jack.
● Do not raise the vehicle while someone is in the vehicle.
