Vehicle Information, Consumer Information and Reporting Safety Defects2-12
To help achieve proper engine and powertrain performance and durability, use only
lubricants of the proper quality. The correct lubricants also help promote engine
efficiency that results in improved fuel economy.
These lubricants and fluids are recommended for use in your vehicle.

RECOMMENDED LUBRICANTS AND CAPACITIES

WARNING
Do not drive across the contour of steep
hills. A slight change in the wheel angle
can destabilize the vehicle, or a stable
vehicle may lose stability if the vehicle
stops its forward motion. Your vehicle
may roll over and lead to a serious injury
or death.
Driving through water

[T
ry to avoid driving in deep standing
water. It may stall your engine and
clog your exhaust pipes.

[ If you need to drive in water, stop
your vehicle, set the vehicle in Multi
Terrain mode and drive under 5 mph
(8 km/h).

[ Do not change gear while driving in
water.
CAUTION
Always drive slowly in water. If you
drive too fast, water may get into the
engine compartment and wet the
ignition system causing your vehicle to
suddenly stop.
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.

loss of power, hard starting problem, etc. replace the fuel filter immediately regardless of maintenance schedule and consult an
authorized HYUNDAI dealer for details.
