Owner maintenance schedule

When you stop for fuel:
• Check for both fuel cell stack and
Device cooling coolant level in
coolant reservoir.
• Check the windshield washer fluid
level.
• Look for low or under-inflated tires.
WARNING
Be careful when checking the
coolant level when the fuel cell
power module is hot. Scalding
hot coolant and steam may
blow out under pressure. This
could cause burns or other seri-
ous injury.
7-6
While operating your vehicle:
• Check for vibrations in the steering
wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead posi-
tion.
• Notice if your vehicle constantly
turns slightly or "pulls" to one side
when traveling on smooth, level
road.
• When stopping, listen and check
for unusual sounds, pulling to one
side, increased brake pedal travel
or "hard-to-push" brake pedal.
• If any slipping or changes in the
operation of your reduction gear
occurs, check the reduction gear
fluid level.
• Check the reduction gear P (Park)
function.
• Check the parking brake.
• Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
• Check coolant level in the coolant
reservoir.
• Check the operation of all exterior
lights, including the brake lights,
turn signals and hazard warning
flashers.
• Check the inflation pressures of all
tires that are worn, show uneven
wear, or are damaged.
• Check for loose wheel lug nuts.
At least twice a year:
(for example, every Spring and
Fall)
• Check radiator, heater and air con-
ditioning hoses for leaks or dam-
age.
• Check windshield washer spray
and wiper operation. Clean wiper
blades with clean cloth dampened
with washer fluid.
• Check headlight alignment.
• Check the seat belts for wear and
function.
