If the word ON, and the on symbol, are lit
on the passenger airbag status indicator, it
means that the front outboard passenger
frontal airbag and knee airbag are allowed
to inflate.
If the word OFF, and the off symbol, are lit
on the passenger airbag status indicator, it
means that the passenger sensing system
has turned off the front outboard passenger
frontal airbag and knee airbag.
If, after several seconds, both status
indicator lights remain on, or if there are no
lights at all, or if the airbag readiness light
is on, there may be a problem with the
lights or the passenger sensing system. See
your dealer for service right away.
{Warning
If the airbag readiness light ever comes
on and stays on, it means that
something may be wrong with the airbag
system. To help avoid injury to yourself
or others, have the vehicle serviced right
away. SeeAirbag Readiness Light 0101
for more information, including important
safety information.
Charging System Light
The charging system light comes on briefly
when the ignition is turned on, but the
engine is not running, as a check to show
the light is working. It should go out when
the engine is started.
If the light stays on, or comes on while
driving, there may be a problem with the
electrical charging system. Have it checked
by your dealer. Driving while this light is on
could drain the battery.
When this light comes on, or is flashing, the
Driver Information Center (DIC) also displays
a message.
If a short distance must be driven with the
light on, be sure to turn off all accessories,
such as the radio and air conditioner. Find a
safe place to stop the vehicle.
Malfunction Indicator Lamp
(Check Engine Light)
This light is part of the vehicle’s emission
control on-board diagnostic system. If this
light is on while the engine is running, a
malfunction has been detected and the
vehicle may require service. The light should
come on to show that it is working when
the ignition is on and the engine is not
running. See Ignition Positions 0174.
Malfunctions are often indicated by the
system before any problem is noticeable.
Being aware of the light and seeking service
promptly when it comes on may prevent
damage.
Caution
If the vehicle is driven continually with
this light on, the emission control system
may not work as well, the fuel economy
may be lower, and the vehicle may not

If equipped with the Tire Pressure Monitor
System (TPMS), this light comes on briefly
when the vehicle is started. It provides
information about tire pressures and
the TPMS.
When the Light Is On Steady
This indicates that one or more of the tires
are significantly underinflated.
A Driver Information Center (DIC) tire
pressure message may also display. Stop as
soon as possible, and inflate the tires to the
pressure value shown on the Tire and
Loading Information label. SeeTire Pressure
0 292.
When the Light Flashes First and Then Is On
Steady
If the light flashes for about a minute and
then stays on, there may be a problem with
the TPMS. If the problem is not corrected,
the light will come on every time the
vehicle is started. See Tire Pressure Monitor
Operation 0295.Engine Oil Pressure Light
Caution
Driving the vehicle with low engine oil
pressure can damage the engine and the
repairs would not be covered by the
vehicle warranty.
If the engine oil pressure light comes on
while driving:
1. Stop in a safe location and turn off the engine.
2. Check the oil level. See Engine Oil
0 264.
3. Add oil if the oil level is below the normal operating range.
4. Restart the vehicle. If the engine oil pressure light stays on for more
than 10 seconds, turn the vehicle
back off. Do not restart the vehicle.
See your dealer for service.
This light should come on briefly when the
engine starts. When the engine is off and
the vehicle is on, the light should remain
illuminated. If it does not come on under
either condition, contact your dealer.
If the light comes on and stays on when the
engine is running, it may not have adequate
oil pressure. The oil level may be low or
there may be some other oil system
problem. Turn the engine off when it is safe
to do so and contact your dealer.
Low Fuel Warning Light
A Low Fuel Warning Light near the fuel
gauge comes on briefly when the ignition is
turned on as a check to show it is working.
It also comes on when the fuel gauge
indicator nears empty. The light turns off
when fuel is added. If it does not, have the
vehicle serviced.

Warning (Continued)
Never run the engine in an enclosed area
that has no fresh air ventilation. For more
information, seeEngine Exhaust0181.
{Warning
Overinflating a tire could cause the tire
to rupture and you or others could be
injured. Be sure to read and follow the
tire sealant and compressor kit
instructions and inflate the tire to its
recommended pressure. Do not exceed
the recommended pressure.
{Warning
Storing the tire sealant and compressor
kit or other equipment in the passenger
compartment of the vehicle could cause
injury. In a sudden stop or collision, loose
equipment could strike someone. Store
the tire sealant and compressor kit in its
original location. If this vehicle has a tire sealant and
compressor kit, there may not be a spare
tire or tire changing equipment, and on
some vehicles there may not be a place to
store a tire.
The tire sealant and compressor can be used
to temporarily seal punctures up to 6 mm
(0.25 in) in the tread area of the tire. It can
also be used to inflate an underinflated tire.
If the tire has been separated from the
wheel, has damaged sidewalls, or has a
large puncture, the tire is too severely
damaged for the tire sealant and
compressor kit to be effective. See
Roadside
Assistance Program 0343.
Read and follow all of the tire sealant and
compressor kit instructions. The kit includes:
1. Sealant Canister Inlet Valve
2. Sealant/Air Hose
3. Base of Sealant Canister
4. Tire Sealant Canister
5. On/Off Button
6. Slot on Top of Compressor
7. Pressure Deflation Button
8. Pressure Gauge

The compressor will inject sealant and air
into the tire.
The pressure gauge (8) will initially show
a high pressure while the compressor
pushes the sealant into the tire. Once
the sealant is completely dispersed into
the tire, the pressure will quickly drop
and start to rise again as the tire inflates
with air only.
11. Inflate the tire to the recommended inflation pressure using the pressure
gauge (8). The recommended inflation
pressure can be found on the Tire and
Loading Information label. See Tire
Pressure 0292.
The pressure gauge (8) may read higher
than the actual tire pressure while the
compressor is on. Turn the compressor off to get an accurate pressure reading.
The compressor may be turned on/off
until the correct pressure is reached.
Caution
If the recommended pressure cannot be
reached after approximately 25 minutes,
the vehicle should not be driven farther.
The tire is too severely damaged and the
tire sealant and compressor kit cannot
inflate the tire. Remove the power plug
from the accessory power outlet and
unscrew the inflating hose from the tire
valve. See
Roadside Assistance Program
0 343.
12. Press the on/off button (5) to turn the tire sealant and compressor kit off.
The tire is not sealed and will continue
to leak air until the vehicle is driven and
the sealant is distributed in the tire.
Therefore, Steps 13–21 must be done
immediately after Step 12.
Be careful while handling the tire sealant
and compressor kit as it could be warm
after usage.
13. Unplug the power plug (9) from the accessory power outlet in the vehicle.

Compact Spare Tire
{Warning
Driving with more than one compact
spare tire at a time could result in loss of
braking and handling. This could lead to a
crash and you or others could be injured.
Use only one compact spare tire at
a time.
If this vehicle has a compact spare tire, it
was fully inflated when new; however, it
can lose air over time. Check the inflation
pressure regularly. It should be 420 kPa
(60 psi).
Stop as soon as possible and check that the
spare tire is correctly inflated after being
installed on the vehicle. The compact spare
tire is designed for temporary use only. The
vehicle will perform differently with the
spare tire installed and it is recommended
that the vehicle speed be limited to 80 km/h
(50 mph). To conserve the tread of the spare
tire, have the standard tire repaired or
replaced as soon as convenient and return
the spare tire to the storage area. When using a compact spare tire, the AWD
(if equipped), ABS, and Traction Control
systems may engage until the spare tire is
recognized by the vehicle, especially on
slippery roads. Adjust driving to reduce
possible wheel slip.
Caution
When the compact spare is installed, do
not take the vehicle through an
automatic car wash with guide rails. The
compact spare can get caught on the rails
which can damage the tire, wheel, and
other parts of the vehicle.
Do not use the compact spare on other
vehicles.
Do not mix the compact spare tire or wheel
with other wheels or tires. They will not fit.
Keep the spare tire and its wheel together.
Caution
Tire chains will not fit the compact spare.
Using them can damage the vehicle and
the chains. Do not use tire chains on the
compact spare.
