5-1. Essential information
Towing eyelets
■Emergency towing procedureRelease the parking brake.
Put the shift lever in “N”.
The engine switch must be in the “ACC” position (engine off) or the “ON”
position (engine on).
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 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.
●Put the vehicle height in the “N” (normal) mode and push the height control
“OFF” switch to turn off rear height control air suspension. Otherwise the auto-
matic leveling function may adjust the vehicle height unexpectedly, resulting in an
accident.
NOTICE
■To prevent causing serious damage to the transmission
Never tow this vehicle from the rear with four wheels on the ground.

CAUTION
■Using the tire jack
Improper use of the tire jack may lead to death or injuries due to the vehicle sud-
denly falling off the jack.
●Do not use the tire jack for any purpose other than replacing tires or installing and
removing tire chains.
●Only use the tire jack that comes with this vehicle for replacing a flat tire.
Do not use it on other vehicles, and do not use other tire jacks for replacing tires
on this vehicle.
●Always check that the tire jack is securely set to the jack point.
●Be sure to turn off the rear height control air suspension and stop the engine.
●Do not raise the vehicle while someone is in it.
●When raising the vehicle, do not put an object on or under the jack.
●Do not raise the vehicle to a height greater than that required to replace the tire.
●Use a jack stand if it is necessary to get under the vehicle.
●Do not put any part of your body under the vehicle supported by a jack.
●Do not start or run the engine while your vehicle is supported by the jack.
Take particular care when lowering the vehicle to ensure that no one working on or
near the vehicle may be injured.
■Using the jack handle
Tighten all the jack handle bolts securely using a Phillips-head screwdriver, to pre-
vent the extension parts from coming apart unexpectedly.
