■Before emergency towingThe “ENGINE START STOP” switch must be in the ACCESSORY mode
(engine off) or IGNITION ON mode (engine running).
Put the four-wheel drive control switch in H4. (The center differential is
unlocked.)
Put the vehicle height in the N mode and press height control switch to
turn off the rear height control air suspension.
Shift the shift lever in N.
Release the parking brake.
CAUTION
■Caution while towing
●Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which place excessive stress on
the emergency towing eyelets and the cables or chains. Always use caution for
the surroundings and other vehicles while towing.
●Do not turn the “ENGINE START STOP” switch off.
Doing so will lock the steering wheel an d prevent operation, possibly causing an
accident and resulting in death or serious injury.
●If the engine is not running, the power assist for the brakes and steering will not
function, making steering and braking more difficult.
