166 Driving and Operating
Driving conditions
Normal uphill road
Steep uphill, steep slope, mountain road with
many sharp curves
Long uphill road
Downhill driving:
Do not overuse the foot brake. This will
cause the brakes to overheat, reducing their
effectiveness. On long downward slopes or
sharp downhill sections of road, use the
engine brake together with the foot brakes
to control the speed.
When the selector lever is in the OD
position, you can drive with the overdrive
off switch ON to allow a gentle engine
brake to be applied.
Push the overdrive off switch to the ON
position at speeds below 101 km/h (63 MPH)
to increase engine braking action when
traveling downgrade.
You can increase engine braking by driving
with the selector lever in the 2 position.

To apply a stronger engine brake on sharp
downhill sections, shift the selector lever to
the 1 position when required.
See Control of a Vehicle 0 110.
Driving at Low Speeds for Sustained Periods
Any low speed applications such as sweeper,
road marking machinery, trash collectors,
highway striping or moving, etc. require the
following treatment to prevent the
automatic transmission fluid (ATF) from
overheating:
Select 1 position during low speed operation
under 18 km/h (11 MPH).
Select 2 position during low speed operation
under 36 km/h (22 MPH).
See Automatic Transmission Fluid
Temperature Warning Light 0 55.
To Stop Your Vehicle
1. To temporarily stop the vehicle, press
the brake pedal firmly while the selector
lever is in OD.
2. Use the parking brake as required. Press
the brake pedal firmly, and firmly apply
the parking brake.
If the vehicle is stationary for a long
time, move the selector lever into the
"P" or "N" position (models with P-range)
or "N" position (models without P-range).
If the selector lever is kept in the "OD"
position, the temperature of the
automatic transmission fluid increases
due to heat from the torque converter.
To ensure reliable brake application, be sure
to use your right foot to press the brake
pedal.
When leaving the driver's seat, follow the
When Parking Your Vehicle procedure.
To Start After Stopping
To start again after stopping your vehicle,
visually check that the selector lever is in
OD, and gradually press the accelerator
pedal to pull away.
