Canada/Mexico-8431502) - 2015 - crc - 1/12/15
1-26 In Brief
The low tire pressure warning light
alerts to a significant loss in
pressure of one of the vehicle's
tires. If the warning light comes on,
stop as soon as possible and inflate
the tires to the recommended
pressure shown on the Tire and
Loading Information label. See
Vehicle Load Limits on page 9-14.
The warning light will remain on until
the tire pressure is corrected.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that the
tire pressures are getting low and
the tires need to be inflated to the
proper pressure.
The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.
SeeTire Pressure Monitor System
on page 10-55.Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and, on most vehicles, displays a
DIC message when it is necessary
to change the engine oil and filter.
The oil life system should be reset
to 100% only following an oil
change.
Resetting the Oil Life System
To reset the engine oil life system:
1. Display OIL LIFE REMAINING
on the DIC. See Driver
Information Center (DIC) (Base
Level) on page 5-29 orDriver
Information Center (DIC)
(Uplevel) on page 5-31. If the
vehicle does not have DIC
buttons, the vehicle must be in
P (Park) to access this display.
2. Press and hold the
Vbutton on
the DIC, or the trip odometer
reset stem if the vehicle does
not have DIC buttons, for
several seconds. The oil life will
change to 100%. The oil life system can also be reset
as follows:
1. Turn the ignition to ON/RUN with
the engine off.
2. Fully press the accelerator pedal slowly three times within
five seconds.
3. Display OIL LIFE REMAINING on the DIC. If the display shows
100%, the system is reset.
See Engine Oil Life System on
page 10-10.
E85 or FlexFuel
Vehicles with a yellow fuel cap can
use either unleaded gasoline or
ethanol fuel containing up to 85%
ethanol (E85). See E85 or FlexFuel
on page 9-70. For all other vehicles,
use only the unleaded gasoline
described under Fuel on page 9-69.

the vehicle (Keyless Access).
.The hood is not closed.
.There is an emission control
system malfunction and the
malfunction indicator lamp is on. The engine will turn off during a
remote vehicle start if:
.The coolant temperature gets
too high.
.The oil pressure gets low.
The RKE transmitter range may be
reduced while the vehicle is running.
Other conditions can affect the
performance of the transmitter. See

The vehicle aerodynamics are
designed to improve fuel economy
performance. This may result in a
pulsing sound when either rear
window is down and the front
windows are up. To reduce the
sound, open either a front window
or the sunroof, if equipped.

{Warning
Children could be seriously
injured or killed if caught in the
path of a closing window. Never
leave keys in a vehicle with
children. When there are children
in the rear seat, use the window
lockout button to prevent
operation of the windows. See
Keys (Key) on page 2-2orKeys
(Keyless) on page 2-4.The driver door has switches that
control all windows. Each
passenger door switch only controls
that window. The power windows
work when the ignition is in ON/

Windows that have the
express-down feature allow the
windows to be lowered without
holding the switch. Press the
window switch fully and release it to
activate the express-down feature.
The express mode can be canceled
at any time by briefly pressing or
pulling the switch.

3-36 Seats and Restraints
The parts of the airbag that come
into contact with you may be warm,
but not too hot to touch. There may
be some smoke and dust coming
from the vents in the deflated
airbags. Airbag inflation does not
prevent the driver from seeing out of
the windshield or being able to steer
the vehicle, nor does it prevent
people from leaving the vehicle.
{Warning
When an airbag inflates, there
may be dust in the air. This dust
could cause breathing problems
for people with a history of
asthma or other breathing trouble.
To avoid this, everyone in the
vehicle should get out as soon as
it is safe to do so. If you have
breathing problems but cannot
get out of the vehicle after an
airbag inflates, then get fresh air
by opening a window or a door.
If you experience breathing(Continued)
Warning (Continued)
problems following an airbag
deployment, you should seek
medical attention.
The vehicle has a feature that may
automatically unlock the doors, turn
on the interior lamps and hazard
warning flashers, and shut off the
fuel system after the airbags inflate.
The feature may also activate,
without airbag inflation, after an
event that exceeds a predetermined
threshold. You can lock the doors,
and turn off the interior lamps and
hazard warning flashers by using
the controls for those features.
{Warning
A crash severe enough to inflate
the airbags may have also
damaged important functions in
the vehicle, such as the fuel (Continued)
Warning (Continued)
system, brake and steering
systems, etc. Even if the vehicle
appears to be drivable after a
moderate crash, there may be
concealed damage that could
make it difficult to safely operate
the vehicle.
Use caution if you should attempt
to restart the engine after a crash
has occurred.
In many crashes severe enough to
inflate the airbag, windshields are
broken by vehicle deformation.
Additional windshield breakage may
also occur from the front outboard
passenger airbag.
.Airbags are designed to inflate
only once. After an airbag
inflates, you will need some new
parts for the airbag system.
If you do not get them, the
airbag system will not be there
to help protect you in another
