engine oil (mineral oil including Semi-synthetic) is used, then the engine oil and engine
oil filter must be replaced as indicated severe maintenance condition.
*3 : To maintain the best braking performance and ABS/ESC performance, use genuine brake
fluid that conform to specifications.

Additional driving conditions

[ Become f
amiliar with the off-road
conditions before driving.

[ Always pay attention when driving off-
road and avoid dangerous areas.

[ Drive slowly when driving in heavy
wind.

[ Reduce vehicle speed when
cornering. The center of gravity
of AWD vehicles is higher than
conventional 2WD vehicles, making
them more likely to roll over when you
rapidly turn corners.

[ Always hold the steering wheel firmly
when you are driving off-road.
WARNING
Do hold the steering wheel tightly
when you are driving off-road. You may
hurt your arm by a sudden steering
maneuver or from steering wheel
rebound due to an impact with objects
on the ground. You could lose control
of the steering wheel which may lead to
serious injury or death.
Emergency Precautions
Tires
When replacing tires, be sure to equip
all four tires with the same size, type,
tread patterns, brand and load-carrying
capacity.
WARNING
Do not use tire and wheel with different
size and type from the one originally
installed on your vehicle. It can affect
the safety and performance of your
vehicle, which could lead to steering
failure or rollover causing serious injury.
In an emergency situation, a compact
spare tire (if equipped) or Tire Mobility
Kit (if equipped) may be used. But,
do not use the compact spare tire
continuously. Repair or replace the
original tire as soon as possible to avoid
failure of the differential or AWD system.
WARNING
Never start or run the engine while
an AWD vehicle is raised on a jack.
The vehicle can slip or roll off of a jack
causing serious injury or death to you or
those nearby.
