Towing eyelet
■Emergency towing procedureRelease the parking brake.
Put the shift lever in “N”.
The “ENGINE START STOP” switch must be in the ACCESSORY mode
(engine off) or the IGNITION ON mode (engine on).
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 eyelet and the cable or chain.
●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 automatic transmission
Never tow this vehicle from the front with the rear wheels (2WD models) or four
wheels (4WD models) on the ground.
This may cause serious damage to the automatic transmission.
