BRAKE FLUID RESERVOIR
The fluid level will drop
slowly as the brakes
wear, and will rise
when the brake
components are
replaced. Fluid levels below the“MAX”line that do
not trigger the brake system warning lamp are
within the normal operating range, there is no need
to add fluid. If the fluid levels are outside of the
normal operating range, the performance of your
brake system could be compromised, seek service
from your dealer immediately.
CLUTCH ADJUSTMENT (IF EQUIPPED)
Check the clutch
adjustment. Refer to
the scheduled
maintenance guide for
the service interval
schedules.
The clutch on your
vehicle is operated by a
cable. As necessary, adjust the clutch as described
below.
1. Turn the engine off and shift into 1 (First).
2. Put your foot under the clutch pedal and gently
pull it up until the pedal stops.
3. Push the clutch pedal down slowly. You will hear a
click as the clutch adjusts itself.
TRANSMISSION FLUID
Checking automatic transmission fluid
(if equipped)
Refer to your scheduled maintenance guide for
scheduled intervals for fluid checks and changes.
Your transmission does not consume fluid. However,
the fluid level should be checked if the transmission
is not working properly, i.e., if the transmission slips
or shifts slowly or if you notice some sign of fluid
leakage.

tire graded 150 would wear one and one-half
(11⁄2) times as well on the government course as a
tire graded 100.
•Traction:The traction grades, from highest to
lowest are AA, A, B, and C. The grades represent
the tire’s ability to stop on wet pavement as
measured under controlled conditions on specified
government test surfaces of asphalt and concrete.
A tire marked C may have poor traction
performance.
•Temperature:The temperature grades are A
(the highest), B and C, representing the tire’s
resistance to the generation of heat and its ability
to dissipate heat when tested under controlled
conditions on a specified indoor laboratory test
wheel.
13.Maximum Permissible Inflation Pressure:
Tire manufactures maximum permissible pressure
and/or the pressure at which the maximum load can
be carried by the tire. This pressure is normally
higher than the manufacturer’s recommended cold
inflation pressure which can be found on either the
tire label or certification label which is located on
the structure by the trailing edge of the driver’s door
or the edge of the driver’s door. The cold inflation
pressure should never be set lower than the
recommended pressure on the label.
Note:You may not find this information on all tires
because it is not required by federal law.
The tire suppliers may have additional markings,
notes or warnings such as standard load, radial
tubeless, etc.
