When driving
CAUTION
●The brake system consists of 2 individual hydraulic systems: if one of the systems
fails, the other will still operate. In this case, the brake pedal should be depressed
more firmly than usual and braking distance becomes longer.
Do not drive your vehicle with only a single brake system. Have your brakes fixed
immediately.
■If the vehicle becomes stuc k or bogged (AWD models)
Do not spin the wheels recklessly when any of the tires is up in the air, or stuck in
sand or mud, etc. This may damage the drive system components or propel the
vehicle forward (or in another direction) and cause an accident.
NOTICE
■When driving the vehicle
●With manual transmission vehicles, do not rest your foot on the clutch pedal while
driving.
Doing so may cause clutch trouble.
●With manual transmission vehicles, do no t use any gears other than the first gear
when starting off and moving forward.
Doing so may damage the clutch.
●With automatic transmission vehicles, do not use the accelerator pedal or
depress accelerator and brake pedals together to hold the vehicle on a hill.
●With manual transmission vehicles, do no t use the clutch to hold the vehicle when
stopping on an uphill grade.
■When parking the vehicle
With automatic transmission vehicles, always put the shift lever in P. Failure to do so
may cause the vehicle to move or the vehicle may accelerate suddenly if the accel-
erator pedal is accidentally depressed.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for a long
time.
Doing so may damage the power steering motor.
●When driving over bumps in the road, drive as slowly as possible to avoid damag-
ing the wheels, underside of the vehicle, etc.
