Height control indicator lightsIf you change the vehicle height mode, the indicator lights change as fol-
lows: • The current mode indicator light will turn off, and the selected modeindicator light will begin flashing.
• Once the change in vehicle height is complete, the selected mode indicator light will change from flashing to continuously lit.
■Operating conditions
●The engine must be running.
●Vehicle speed must be within the acceptable range for the selected mode.
■Automatic change in vehicle height
If the vehicle speed exceeds 19 mph (30 km/h) when in the high mode, or 7 mph
(12 km/h) when in the low mode, normal mode is automatically selected.
■Turning off the rear height control air suspension
●The system will remain off until the switch is pushed again, even if the engine
switch is turned off.
●Even if the rear height control air suspension is turned off, the system automati-
cally selects the normal mode if the vehicle’s speed exceeds 19 mph (30 km/h).
■Automatic leveling function
The vehicle is adjusted to a fixed height for each mode, regardless of the number of
occupants and the luggage load.

2-4. Using other driving systems
CAUTION
Failure to observe the following precautions may result in an accident.
■ Using the “HI” (high) mode
This mode should only be used for rough off-road conditions. Because the vehicle’s
center of gravity is higher when in the high mode, the vehicle may become unstable
when turning abruptly.
■When loading cargo on the roof luggage carrier
Do not select the “HI” (high) mode. Because the vehicle’s center of gravity is higher
when in the high mode, the vehicle may become unstable when turning abruptly
and unexpected loss of control or vehicle rollover may occur.
■When jacking up the vehicle or installing tire chains
Turn off the rear height control air suspension and stop the engine, otherwise the
vehicle height may change due to the automatic leveling function.
■ When driving through water deeper than 28 in. (700 mm)
Select the “HI” (high) mode, turn off the rear height control air suspension and drive
at 19 mph (30 km/h) or slower. Otherwise, the vehicle height may change due to
the automatic leveling function.
■If your vehicle must be towed
Put the vehicle height in the normal mode and turn off the rear height control air
suspension, otherwise the vehicle height may change due to the automatic leveling
function.
■If your vehicle becomes stuck in a ditch
Turn off the rear height control air suspension, otherwise the vehicle height may
change due to the automatic leveling function.

Winter driving tips
Carry out the necessary preparations and inspections before driving the
vehicle in winter. Always drive the vehicle in a manner appropriate to the
prevailing weather conditions.
■Pre-winter preparations
●Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Washer fluid
● Have a service technician inspect the level and specific gravity of
battery electrolyte.
● Have the vehicle fitted with four snow tires or purchase a set of
tire chains for the rear tires.
Ensure that all tires are the same size and brand, and that chains match
the size of the tires.
■ Before driving the vehicle
Perform the following according to the driving conditions.
●Do not try to forcibly open a window or move a wiper that is fro-
zen. Pour warm water over the frozen area to melt the ice. Wipe
away the water immediately to prevent it from freezing.
● To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
● Remove any ice that has accumulated on the vehicle chassis.
● Periodically check for and remove any excess ice or snow that
may have accumulated in the wheel well or on the brakes.

2-5. Driving information
●Note that when making a turn, the trailer wheels will be closer than the
vehicle wheels to the inside of the turn. Compensate by making a
larger than normal turning radius.
● Crosswinds and rough roads will adversely affect handling of your
vehicle and trailer, causing sway. Periodically check the rear to prepare
for being passed by large trucks or buses, which may cause your vehi-
cle and trailer to sway. If swaying occurs, firmly grip the steering wheel,
reduce speed immediately but gradually, and steer straight ahead.
Never increase speed. If you make no extreme correction with the
steering or brakes, your vehicle and trailer will stabilize.
● Take care when passing other vehicles. Passing requires considerable
distance. After passing a vehicle, do not forget the length of your
trailer, and be sure you have plenty of room before changing lanes.
● In order to maintain efficient engine braking and electrical charging
performance, do not use overdrive. Transmission shift range position
must be in “4”.
● Due to the added load of the trailer, your vehicle’s engine may overheat
on hot days (at temperatures over 85°F [30°C] when driving up a
long or steep grade. If the engine coolant temperature gauge indicates
overheating, immediately turn off the air conditioning (if in use), pull
your vehicle off the road and stop in a safe spot. (
