uuFor Safe Driving uImportant Safety Precautions
Safe Driving
■Pay appropriate attention to the task of driving safely
Engaging in cell phone conversation or other activities that keep you from paying
close attention to the road, other vehicles, and pedestrians could lead to a crash.
Remember, situations can change quickly, and only you can decide when it is safe to
divert some attention away from driving.
■Control your speed
Excessive speed is a major factor in crash injuries and deaths. Generally, the higher
the speed, the greater the risk, but serious injuries can also occur at lower speeds.
Never drive faster than is safe for current conditions, regardless of the maximum
speed posted.
■Keep your vehicle in safe condition
Having a tire blowout or a mechanical failure can be extremely hazardous.
To reduce the possibility of such problems, check your tire pressures and condition
frequently, and perform all regul arly scheduled maintenance.
■Do not leave children unattended in the vehicle
Children, pets, and people needing assistance left unattended in the vehicle may be
injured if they activate one or more of the vehicle controls. They may also cause the
vehicle to move, resulting in a crash in wh ich they and/or another person(s) can be
injured or killed. Also, depending on the am bient temperature, the temperature of
the interior may reach extreme levels, which can result in harm or death. Even if the
climate control system is on, never leave them in the vehicle unattended as the
climate control system can shut off at any time.

uuAirbags uAirbag Care
Safe Driving
Airbag Care
You do not need to, and should not, perform any maintenance on or replace any
airbag system components yourself. However, you should have your vehicle
inspected by a dealer in the following situations:
■When the airbags have deployed
If an airbag has inflated, the control unit and other related parts must be replaced.
Similarly, once an automatic seat belt te nsioner has been activated, it must be
replaced.
■When the vehicle has been in a moderate-to-severe collision
Even if the airbags did not inflate, have yo ur dealer inspect the following: the driver’s
seat position sensor, weight sensors in the passenger’s seat, seat belt tensioners for
the front seats and outer rear seats, and each seat belt that was worn during the
crash.
■Do not remove or modify a front seat without consulting a dealer
This would likely disable or affect the proper operation of the driver’s seat position
sensor or the weight sensors in the passenge r’s seat. If it is necessary to remove or
modify a front seat to accommodate a pe rson with disabilities, contact an Acura
dealer, or for U.S. vehicles, Acura Client Relations at 1-800-382-2238 and for
Canadian vehicles, Acura Client Services at 1-888-9-ACURA-9.
1Airbag Care
We recommend against the use of salvaged airbag
system components, includi ng the airbag, tensioners,
sensors, and control unit.
