Air bag inflation conditions
OBC3030027
Front air bags
Front air bags are designed to inflate
in a frontal collision depending on the
severity of impact of the front collision.
OBC3030028R
OAC3039029R
Side and curtain air bags
Side and curtain air bags are designed
to inflate when an impact is detected
by side collision sensors depending on
the severity of impact resulting from
a side impact collision. Although the
driver’s and front passenger’s air bags
are designed to inflate only in frontal
collisions, they also may inflate in other
types of collisions if the front impact
sensors detect a sufficient impact. Side
and curtain air bags are designed to
inflate only in side impact collisions, but
they may inflate in other collisions if the
side impact sensors detect a sufficient
impact. If the vehicle chassis is impacted
by bumps or objects on unimproved
roads, the air bags may deploy. Drive
carefully on unimproved roads or on
surfaces not designed for vehicle traffic to
prevent unintended air bag deployment.

Air bag non-inflation conditions
OBC3030029
In certain low-speed collisions the air
bags may not deploy. The air bags are
designed not to deploy in such cases
because they may not provide benefits
beyond the protection of the seat belts.
OBC3030030
Front air bags are not designed to inflate
in rear collisions, because occupants
are moved backward by the force of
the impact. In this case, inflated air
bags would not provide any additional
benefit.
OBC3030028R
Front air bags may not inflate in side
impact collisions, because occupants
move in the direction of the collision,
and thus in side impacts, front air
bag deployment would not provide
additional occupant protection.
However, side and curtain air bags may
inflate depending on the severity of
impact.
OGB034038
In an angled collision, the force of
impact may direct the occupants in a
direction where the air bags would not
be able to provide any additional benefit,
and thus the sensors may not deploy any
air bags.

Safety system
OBC3030032
Just before impact, drivers often brake
heavily. Such heavy braking lowers the
front portion of the vehicle causing it
to “ride” under a vehicle with a higher
ground clearance. Air bags may not
inflate in this “under-ride” situation
because deceleration forces that are
detected by sensors may be significantly
reduced by such “underride” collisions.
OHI038166
Front air bags may not inflate in
rollover accidents because front air
bag deployment would not provide
additional occupant protection.

inflate when the vehicle is rolled over
by a side impact collision, if the vehicle
is equipped with side and/or curtain air
bags.
OBC3030033
Air bags may not inflate if the vehicle
collides with objects such as utility poles
or trees, where the point of impact is
concentrated and the collision energy is
absorbed by the vehicle structure.

Electric Chromic Mirror (ECM)
(if equipped)
OBC3050014
The electric rearview mirror
automatically controls the glare from the
headlamp of the vehicle behind you in
nighttime or low light driving conditions.
When the engine is running, the glare is
automatically controlled by the sensor
(1) mounted in the rearview mirror. The
sensor detects the light level around
the vehicle, and automatically adjusts
to control the headlamp glare from
vehicles behind you.
Whenever the shift button is placed in R
(Reverse), the mirror will automatically
go to the brightest setting in order to

Your vehicle is equipped with both left-
hand and right-hand outside rearview
mirrors.
The mirror heads can be folded to
prevent damage during an automatic car
wash or when passing through a narrow
street.
When the vehicle speed is over 9.3 mph
(15 km/h), the outside rearview mirror

(if equipped)
The rain sensor located at the top of the
windscreen glass senses the amount of
rainfall and controls the wiping cycle for
the proper interval. The wiper operation
time will be automatically controlled,
depending on rainfall.
When the rain stops, the wiper stops. To
vary the speed setting, turn the speed

If the wiper switch is set in AUTO mode
when the ignition switch is in the ON
position, the wiper will operate once to
perform a self-check of the system. Set
the wiper to the OFF position when the
wiper is not in use.
WARNING
To avoid personal injury from the
windscreen wipers, when the engine
is running and the windscreen wiper
switch is placed in the AUTO mode:
Do not touch the upper end of the
windscreen glass facing the rain sensor.
Do not wipe the top of the windscreen
glass with a damp or wet cloth.
Do not put pressure on the windscreen

windscreen using the defroster to
prevent the washer fluid from freezing
on the windscreen and obscuring your
vision which could result in an accident
and serious injury or death.

Driving your vehicle
Your vehicle may be equipped with
the ISG system, which reduces fuel
consumption by stopping and restarting
the engine automatically.
The engine starts automatically as soon
as the starting conditions are met.
NOTICE
When the engine automatically starts
by the ISG system, some warning lights
(ABS, ESC, ESC OFF, EPS or Parking
brake warning light) may turn on for a
few seconds. This happens because of
low battery voltage. It does not mean
the system is malfunctioning.
Activating the ISG
Prerequisite for activation
The ISG system operates in the following
situations.

[The driver’s seatbelt is fastened

[The driver’s door and bonnet are
closed

[The brake vacuum pressure is
adequate

[The battery sensor is activated and the
battery is sufficiently charged

[Outside temperature is not too low or
too high

[The vehicle is driven over a constant
