Cold weather operation
It may take longer for the vehicle height to change if the suspension fluid tempera-
ture drops below 5°F (-15°C).
The 4-Wheel AHC does not operate when the suspension fluid temperature drops
below -22°F (-30°C). ●

change. Once the vehicle has been driven for a short time and the suspension
fluid has been warmed to within normal operating limits, the 4-Wheel AHC will
begin operating and the vehicle height wi ll automatically change to the selected
mode. ●

to select the desired vehicle height.■
Parking and stopping tips ●
If you immediately stop the engine after off-road driving, the vehicle height may
gradually lower. When parking, make su re there is nothing under the vehicle
that may come in contact with the underbody. The vehicle will return to the set
height when the engine is started. ●
The vehicle height may change as the temperature changes when the engine is
stopped. The vehicle will return to the set height when the engine is started.■
Propeller shaft noise
If the vehicle height is adjusted on a slope, or with the shift lever in a position other
than “P” or “N” while the vehicle is stop ped, you may hear a sound caused by the
expansion and contraction of the propeller shaft. This does not indicate a malfunc-
tion. ■

If a malfunction occurs in the 4-Wheel AHC, normal mode is automatically
selected. However, the system may not sw itch to normal mode depending on the
location of the malfunction.
The warning message is displayed on the multi-information display, and the 4-
Wheel AHC cannot be activated until the malfunction is corrected.
Stop the engine and start it again. If th e warning message turns off, the system is

Advice for driving on slippery roads ●
If you shift the four-wheel drive control switch to “L4” and the shift lever to the
“2” range of “S” or “D” (vehicles with paddle shift switches) while driving in
steep off-road areas, the output of the brake can be controlled effectively by the
Active TRAC, which assists the driver to control the driving power of 4 wheels. ●
Use the “1” range of “S” or “D” (vehicles with paddle shift switches) of the shift
lever for maximum power and traction wh en your wheels get stuck or when
driving down a steep incline.■

The indicator light blinks while lock ing/unlocking the center differential.■
The center differential lock/unlock switch can be operated when ●
The “ENGINE START STOP” switch is in IGNITION ON mode.●
The vehicle speed is less than 60 mph (100 km/h).■
Locking/unlocking the center differential ●
When the four-wheel drive control switch is in L4 with the center differential
locked, VSC is automatically turned off. (The center differential lock and VSC
OFF indicator lights come on.) ●
If the operation is not completed, the center differential lock indicator blinks. If
the indicator light does not turn off when unlocking the center differential, drive
straight ahead while accelerating or decelerating, or drive in reverse. ●
If the center differential lock/unlock is not completed within 5 seconds while
the cruise control system is on, cancel the cruise control system.
