Loose Fuel Cap warning
The Loose Fuel Cap warning appears in the
vehicle information display when the fuel-
filler cap is not tightened correctly after the
vehicle has been refueled. It may take a few
driving trips for the warning to be displayed.
To turn off the warning, perform the

(P.3-26).)
2. Tighten the fuel-filler cap until a single click is heard.
3. Push the
orswitchon the
steering wheel for longer than 1 second to turn off the Loose Fuel Cap warning
after tightening the fuel-filler cap.
WARNING
.
Do not adjust the steering wheel
while driving. You could lose control
of your vehicle and cause an accident.
. Do not adjust the steering wheel any
closer to you than is necessary for
proper steering operation and com-
fort. The driver’s air bag inflates with
great force. If you are unrestrained,
leaning forward, sitting sideways or
out of position in any way, you are at
greater risk of injury or death in a
crash. You may also receive serious or
fatal injuries from the air bag if you
are up against it when it inflates.
Always sit back against the seatback
and as far away as practical from the
steering wheel. Always use the seat
belts.
TILT/TELESCOPIC STEERING

— If an electrical equipment is being usedin or near the vehicle
— There is a malfunction in the TPMS system
— There is a malfunction in the horn or hazard indicators
. If the Tire Inflation Indicator does not
operate due to TPMS interference, move
the vehicle about 3 ft (1 m) backward or
forward and try again.
If the Tire Inflation Indicator is not working,
use a tire pressure gauge.
AVOIDING COLLISION AND
ROLLOVER
WARNING
Failure to operate this vehicle in a safe
and prudent manner may result in loss of
control or an accident.
Be alert and drive defensively at all times.
Obey all traffic regulations. Avoid excessive
speed, high speed cornering, or sudden
steering maneuvers, because these driving
practices could cause you to lose control of
your vehicle. As with any vehicle, a loss of
control could result in a collision with other
vehicles or objects, or cause the vehicle to rollover, particularly if the loss of control
causes the vehicle to slide sideways.
Be
attentive at all times, and avoid driving when
tired. Never drive when under the influence
of alcohol or drugs (including prescription or
over-the-counter drugs which may cause
drowsiness). Always wear your seat belt as
outlined in the “Seat belts” (P.1-12) of this
manual, and also instruct your passengers to
do so.
Seat belts help reduce the risk of injury in
collisions and rollovers. In a rollover crash,
an unbelted or improperly belted person is
significantly more likely to be injured or
killed than a person properly wearing a seat
belt.
OFF-ROAD RECOVERY
If driving the right side or left side wheels
may unintentionally leave the road surface.
Maintain control of the vehicle by following
the procedure below. Please note that this
procedure is only a general guide. The vehicle
must be driven as appropriate based on the
conditions of the vehicle, road and traffic.
1. Remain calm and do not overreact.
2. Do not apply the brakes.
3. Maintain a firm grip on the steering
wheel with both hands and try to hold
a straight course. 4. When appropriate, slowly release the
accelerator pedal to gradually slow the
vehicle.
5. If there is nothing in the way, steer the vehicle to follow the road while the
vehicle speed is reduced. Do not attempt
to drive the vehicle back onto the road
surface until vehicle speed is reduced.
6. When it is safe to do so, gradually turn the steering wheel until both tires return
to the road surface. When all tires are on
the road surface, steer the vehicle to stay
in the appropriate driving lane.
.If you decide that it is not safe to
return the vehicle to the road surface
based on vehicle, road or traffic
conditions, gradually slow the vehicle
to a stop in a safe place off the road.
RAPID AIR PRESSURE LOSS
Rapid air pressure loss or a “blow-out” can
occur if the tire is punctured or is damaged
due to hitting a curb or pothole. Rapid air
pressure loss can also be caused by driving
on under-inflated tires.
Rapid air pressure loss can affect the
handling and stability of the vehicle, espe-
cially at highway speeds.
Help prevent rapid air pressure loss by
maintaining the correct air pressure and
visually inspect the tires for wear and

belted or radial), and tread pattern
on all four wheels. Install tire chains
on the rear wheels when driving on
slippery roads and drive carefully.
. This vehicle is not designed for off-
road (rough road) use. Do not drive
on sandy or muddy roads that tires
may get stuck in.
. For AWD equipped vehicles, do not
attempt to raise two wheels off the
ground and shift the transmission to
any D (Drive) or R (Reverse) position
with the engine running. Doing so
may result in drivetrain damage or
unexpected vehicle movement which
could result in serious vehicle damage
or personal injury.
. Do not attempt to test an AWD
equipped vehicle on a 2-wheel dy-
namometer (such as the dynam-
ometers used by some states for
emissions testing), or similar equip-
ment even if the other two wheels are
raised off the ground. Make sure you
inform test facility personnel that
your vehicle is equipped with AWD
before it is placed on a dynamometer.
Using the wrong test equipment may
result in drivetrain damage or unex-
pected vehicle movement which could
result in serious vehicle damage or personal injury.
. When a wheel is off the ground due
to an unlevel surface, do not spin the
wheel excessively.WARNING
Do not operate the push-button ignition
switch while driving the vehicle except in
an emergency. (The engine will stop
when the ignition switch is pushed 3
consecutive times or the ignition switch
is pushed and held for more than 2
seconds.) If the engine stops while the
vehicle is being driven, this could lead to
a crash and serious injury.
Before operating the push-button ignition
switch, be sure to move the shift lever to the
P (Park) position.
