Fuel pump shut off system
Follow the procedure below to restart the engine after the system is
activated.Vehicles without a smart key system Turn the engine switch to the “ACC” or “LOCK” position.
Restart the engine.
Vehicles with a smart key system
Turn the “ENGINE START STOP” switch off.
Restart the engine.
NOTICE
■Before starting the engine
Inspect the ground under the vehicle.
If you find that fuel has leaked onto the ground, the fuel system has been
damaged and is in need of repair. Do not restart the engine.
To minimize the risk of fuel leakage when the engine stalls or when
an airbag inflates upon collision , the fuel pump shut off system
stops the supply of fuel to the engine.

SRS warning light
This warning light system monitors the airbag sensor assembly, front airbag
sensors, side and curtain shield airbag sensors, curtain shield airbag sen-
sors, floor sensor, driver's seat belt buckle switch, front passenger occupant
classification system, SRS airbag on-off indicator, roll sensing of curtain
shield airbags off indicator, front passenger's seat belt buckle switch, seat
belt pretensioner assemblies, inflators, interconnecting wiring and power
sources. ( P. 121)
■ Key reminder buzzer (vehicl es without a smart key system)
The buzzer indicates that the key has not been removed with the engine off
and the driver’s door opened.
■ Open moon roof reminder buzzer (if equipped)
The buzzer indicates that the moon roof is not fully closed with the engine off
and the driver’s door opened.
■ Front passenger detection sensor, passenger seat belt reminder and
warning buzzer
● If luggage is placed on the front passenger seat, the front passenger
detection sensor may cause the warning light to flash and the warning
buzzer to sound even if a passenger is not sitting in the seat.
● If a cushion is placed on the seat, the sensor may not detect a passen-
ger, and the warning light may not operate properly.
■ If the malfunction indicator lamp comes on while driving
First check the following:
● Is the fuel tank empty?
If it is, fill the fuel tank immediately.

CAUTION
■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle
placard or tire inflation pressure
label (tire and load information label). (If your vehicle has tires of a differ-
ent size than the size indicated on the vehicle placard or tire inflation
pressure label [tire and load information label], you should determine the
proper tire inflation pr essure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS-ti re pressure warning system) that
illuminates a low tire pressure telltal e (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Accordingly,
when the low tire pressure telltale (tire pre ssure warning light) illumi-
nates, you should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel effi ciency and tire tread life, and may
affect the vehicle's hand ling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper ti re maintenance, an d it is the driver's responsibility to
maintain correct tire pressure, even if under-inflation has not reached the
level to trigger illu mination of the TPMS low tire pressure telltale (tire
pressure warning light).

If the engine will not star t
If the engine will not start even though correct starting procedures
are being followed ( P. 170, 173), consider each of the following
points:
■ The engine will not start even though the starter motor
operates normally.
One of the following may be the cause of the problem:
●There may not be sufficient fuel in the vehicle’s tank.
Refuel the vehicle.
● The engine may be flooded.
Try to restart the engine again following correct starting proce-
dures. ( P. 170, 173)
● There may be a malfunction in the engine immobilizer system.
( P. 1 1 3 )
■ The starter motor turns over slowly, the interior lights and
headlights are dim, or the horn does not sound or sounds at
a low volume.
One of the following may be the cause of the problem:
●The battery may be discharged. ( P. 623)
● The battery terminal connec tions may be loose or corroded.
■ The starter motor does not turn over.
The engine starting system may be malfunctioning due to an
electrical problem such as an open circuit or a blown fuse. How-
ever, an interim measure is available to start the engine.
