WARNING
• Do not leave children or adults who would normally require the support
of others alone in your vehicle. Pets
should not be lef t alone either. They
could accidentally injure themselves
or others through inadvertent op-
eration of the vehicle. Also, on hot,
sunny days, temperatures in a
closed vehicle could quickly become
high enough to cause severe or pos-
sibly fatal injuries to people or ani-
mals.
• Properly secure all cargo with ropes or straps to help prevent it from slid-
ing or shif ting. Do not place cargo
higher than the seatbacks. In a sud-
den stop or collision, unsecured
cargo could cause personal injury.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure
label. (If your vehicle has tires of a different size than the size indicated on the vehicle
placard or tire inflation pressure label, you
should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that illuminates
a low tire pressure telltale when one or
more of your tires is significantly under-
inflated. Accordingly, when the low tire
pressure telltale illuminates, you should
stop and check your tires as soon as pos-
sible, and inflate them to the proper pres-
sure. Driving on a significantly under-
inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also
reduces power efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a substi-
tute for proper tire maintenance, and it is
the driver’s responsibility to maintain cor-
rect tire pressure, even if under-inflation
has not reached the level to trigger illumi-
nation of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicatewhen the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction,
the telltale will flash for approximately one
minute and then remain continuously illu-
minated. This sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists. When the malfunc-
tion indicator is illuminated, the system
may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions
may occur for a variety of reasons, includ-
ing the installation of replacement or alter-
nate tires or wheels on the vehicle that
prevent the TPMS from functioning prop-
erly. Always check the TPMS malfunction
telltale af ter replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.
Additional information
• When replacing a wheel without the TPMS
such as the spare tire, the TPMS does not
monitor the tire pressure of the spare tire.
PRECAUTIONS WHEN STARTING AND
DRIVING
5-4Starting and driving

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
While driving, the right side or lef t side
wheels may unintentionally leave the road
surface. If this occurs, maintain control of
the vehicle by following the procedure be-
low. 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 ac- celerator pedal to gradually slow the
vehicle. 5. If there is nothing in the way, steer the
vehicle to follow the road while the ve-
hicle speed is reduced. Do not attempt
to drive the vehicle back onto the road
surface until the 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 han-
dling and stability of the vehicle, especially
at highway speeds. Help prevent rapid air pressure loss by
maintaining the correct air pressure and
visually inspecting the tires for wear and
damage. For additional information, refer
to “Wheels and tires” in the “Maintenance
and do-it-yourself ” section of this manual.
If a tire rapidly loses air pressure or “blows-
out” while driving, 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.
WARNING
The following actions can increase the
chance of losing control of the vehicle
if there is a sudden loss of tire air pres-
sure. Losing control of the vehicle may
cause a collision and result in personal
injury.
• The vehicle generally moves or pulls in the direction of the flat tire.
• Do not rapidly apply the brakes.
• Do not rapidly release the accelera- tor pedal.
• Do not rapidly turn the steering wheel.
