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
be cautious of the surroundings and other vehicles while towing.
● Vehicles with a smart key system: Do not turn the “ENGINE START
STOP” switch off.
Doing so will lock the steering wheel and prevent operation, possibly caus-
ing 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.
NOTICE
■To prevent causing serious damage to the transmission and transfer
(4WD models) when towing using a wheel-lift type truck
2WD models: Never tow this vehicle from the front with the rear wheels on
the ground.
4WD models: Never tow this vehicle with any of the wheels in contact with
the ground.
■ To prevent damage to the vehicle when towing using a wheel-lift type
truck
● 2WD models without a smart key system: Do not tow the vehicle from the
rear when the engine switch is in the “LOCK” position or the key is
removed. The steering lock mechanism is not strong enough to hold the
front wheels straight.
● 2WD models with a smart key system: Do not tow the vehicle from the rear
when the “ENGINE START STOP” switch is off. The steering lock mecha-
nism is not strong enough to hold the front wheels straight.
● When raising the vehicle, ensure adequate ground clearance for towing at
the opposite end of the raised vehicle. Without adequate clearance, the
vehicle could be damaged while being towed.
