Just before impact, drivers often brake
heavily. Such heavy braking lowers the
front portion of the vehicle causing it
to “ride” under a vehicle with a higher
ground clearance. Air bags may not
inflate in this “underride” situation
because deceleration forces that are
detected by sensors may be significantly
reduced by such “underride” collisions.
ONX4030053
Front air bags may not inflate in
rollover accidents because front air bag
deployment would not provide additional
occupant protection.
However, the side and curtain air bags
and front center air bag may inflate in a
rollover situation, when it is detected by
the rollover sensor.
ONX4030052
Air bags may not inflate if the vehicle
collides with objects such as utility poles
or trees, where the point of impact is
concentrated and the collision energy is
absorbed by the vehicle structure.

Driving your vehicle

Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel hub.
Drive through any water slowly. Allow
adequate stopping distance because
brake performance may be reduced.
After driving through water, dry the
brakes by gently applying them several
times while the vehicle is moving slowly.
Highway driving
Tires
Adjust the tire inflation, as specified.
Under-inflation may overheat or damage
the tires.
Do not install worn-out or damaged tires,
which may reduce traction or fail the
braking operation.
Information
Never over-inflate your tires above the
maximum inflation pressure, as specified
on your tires.
Fuel, engine coolant and engine oil
Driving at higher speeds on the highway
consumes more fuel and is less efficient
than driving at a slower, more moderate
speed. Maintain a moderate speed in
order to conserve fuel when driving on
the highway.
Be sure to check both the engine coolant
level and the engine oil before driving.
Drive belt
A loose or damaged drive belt may
overheat the engine.
Reducing the risk of a rollover
Your multi-purpose passenger vehicle is
defined as a Sports Utility Vehicle (SUV).
SUV’s have higher ground clearance
and a narrower track to make them
capable of performing in a wide variety
of off-road applications. The specific
design characteristics give them a higher
center of gravity than ordinary vehicles
making them more likely to roll over if
you make abrupt turns. Utility vehicles
have a significantly higher rollover rate
than other types of vehicles. Due to this
risk, driver and passengers are strongly
recommended to buckle their seat belts.
In a rollover crash, an unbelted person
is significantly more likely to die than a
person wearing a seat belt.
There are steps that a driver can make
to reduce the risk of a rollover. If at all
possible, avoid sharp turns or abrupt
maneuvers, do not load your vehicle
with heavy cargo on the roof, and never
modify your vehicle in any way.
WARNING
Utility vehicles have a significantly
higher rollover rate than other types of
vehicles. To prevent rollovers or loss of
control:
• Take corners at slower speeds than
you would with a passenger vehicle.
• Avoid sharp turns and abrupt
maneuvers.
• Do not modify your vehicle in any
way that you would raise the center
of gravity.
• Keep tires properly inflated.
• Do not carry heavy cargo on the roof.
WARNING
In a rollover crash, an unbelted person
is significantly more likely to die than a
person wearing a seat belt. Make sure
all passengers are wearing their seat
belts.

[B] : Lane changing vehicle,
[C] : Same lane vehicle
When a vehicle in front of you
merges out of the lane, Forward
Collision-Avoidance Assist may not
immediately detect the vehicle that
is now in front of you.
In this case, you must maintain a safe
braking distance, and if necessary,
steer the vehicle and depress the
brake pedal to reduce your driving
speed in order to maintain a safe
distance.•

If the vehicle in front of you has
cargo that extends rearward from
the cab, or when the vehicle in front
of you has higher ground clearance,
additional special attention is
required. Forward Collision-
Avoidance Assist may not be able
to detect the cargo extending from
the vehicle. In these instances,
you must maintain a safe braking
distance from the rearmost object,
and if necessary, steer the vehicle
and depress the brake pedal to
reduce your driving speed in order to
maintain distance.
