2–44
Essential Safety Equipment
SRS Air Bags
Do not attach objects on or around the area where a side air bag deploys: Attaching objects to the front seat in such a way as to cover the outboard side of the
seat in any way is dangerous. In an accident the object could interfere with the side
air bag, which infl ates from the outboard side of the front seats, impeding the added
protection of the side air bag system or redirecting the air bag in a way that is dangerous.
Furthermore, the bag could be cut open releasing the gas.
Do not hang net bags, map pouches or backpacks with side straps on the front seats.
Never use seat covers on the front seats. Always keep the side air bag modules in your
front seats free to deploy in the event of a side collision.

Do not attach objects on or around the area where a curtain air bag deploys: Attaching objects to the areas where the curtain air bag activates such as on the
windshield glass, side door glass, front and rear window pillars and along the roof edge
and assist grips is dangerous. In an accident the object could interfere with the curtain
air bag, which infl ates from the front and rear window pillars and along the roof edge,
impeding the added protection of the curtain air bag system or redirecting the air bag in
a way that is dangerous. Furthermore, the bag could be cut open releasing the gas.
Do not place hangers or any other objects on the assist grips. When hanging clothes,
hang them on the coat hook directly. Always keep the curtain air bag modules free to
deploy in the event of a side collision or roll-over accident.

Do not touch the components of the supplemental restraint system after the air bags
have infl ated:
Touching the components of the supplemental restraint system after the air bags have
infl ated is dangerous. Immediately after infl ation, they are very hot. You could get burned.

Never install any front-end equipment to your vehicle: Installation of front-end equipment, such as frontal protection bar (kangaroo bar, bull
bar, push bar, or other similar devices), snowplow, or winches, is dangerous. The air bag
crash sensor system could be aff ected. This could cause air bags to infl ate unexpectedly,
or it could prevent the air bags from infl ating during an accident. Front occupants could
be seriously injured.

Do not modify the suspension: Modifying the vehicle suspension is dangerous. If the vehicle's height or the suspension is
modifi ed, the vehicle will be unable to accurately detect a collision or roll-over accident
resulting in incorrect or unexpected air bag deployment and the possibility of serious
injuries.

Before Driving
Driving Tips
Driving on Uneven Road
Your vehicle's suspension and underbody can be damaged if driven on rough/uneven roads
or over speed bumps at excessive speeds. Use care and reduce speed when \
traveling on
rough/uneven roads or over speed bumps.
Use care not to damage the vehicle's underbody, bumpers or muffl er(s) when driving under
the following conditions:
 y Ascending or descending a slope with a sharp transition angle y Ascending or descending a driveway or trailer ramp with a sharp transiti\
on angle
This vehicle is equipped with low profi le tires allowing class-leading performance and
handling. As a result, the sidewall of the tires are very thin and the tires and w\
heels can be
damaged if driven through potholes or on rough/uneven roads at excessive\
speeds. Use care
and reduce speed when traveling on rough/uneven roads or through pothole\
s.

4–119
When Driving
Lane Departure Warning System (LDWS)
CAUTION
Do not modify the suspension. If the vehicle height or the damping force of the
suspensions is changed, the LDWS may not operate correctly.
NOTE
 y If your vehicle deviates from its traffi c lane, the LDWS operates (warning sound and
indicator light). Steer the vehicle adequately to drive the vehicle to \
the center of the lane.
 y When the turn signal lever is operated for a lane change, the LDWS warni\
ng is
automatically canceled. The LDWS warning becomes operable when the turn \
signal lever
is returned and the system detects the white or yellow lines.
 y If the steering wheel, accelerator pedal, or brake pedal is operated abr\
uptly and the
vehicle moves close to a white or yellow line, the system determines tha\
t the driver is
making a lane change and the LDWS warning is automatically canceled.
 y The LDWS may not operate during the period immediately after the vehicle\
has deviated
from its lane and the LDWS has operated, or the vehicle deviates from its lane repeatedly
within a short period of time.
 y The LDWS does not operate if it does not detect the white or yellow line\
s of the traffi c
lane.
