2019 HONDA RIDGELINE maintenance

Event Data Recorders
This vehicle is equipped with an event data recorder (EDR).
The main purpose of an EDR is to record, in certain crash or near
crash-like situations, such as an air bag deployment or hitting a
road obstacle, data that will assist in understanding how a vehicle’s
systems performed. The EDR is designed to record data related
to vehicle dynamics and safety systems for a short period of
time, typically 30 seconds or le ss. The EDR in this vehicle is
designed to record such data as:
• How various systems in your vehicle were operating;
• Whether or not the driver and passenger safety belts were
buckled/fastened;
3WARNING
California Proposition 65 Warning
Operating, servicing and maintaining a
passenger vehicle or off-highway motor
vehicle can expose you to chemicals including
engine exhaust, carbon monoxide,
phthalates, and lead, which are known to the
State of California to cause cancer and birth
defects or other reproductive harm. To
minimize exposure, avoid breathing exhaust,
do not idle the engine except as necessary,
service your vehicle in a well-ventilated area
and wear gloves or wash your hands
frequently when servicing your vehicle. For
more information go to
www.P65Warnings.ca.gov/passenger-vehicle.
• How far (if at all) the driver was depressing the accelerator
and/or brake pedal; and,
• How fast the vehicle was traveling.
These data can help provide a better understanding of the
circumstances in which crashes and injuries occur. NOTE: EDR data
are recorded by your vehicle only if a non-trivial crash situation
occurs; no data are recorded by the EDR under normal driving
conditions and no personal data (e.g., name, gender, age, and
crash location) are recorded.
However, other parties, such as law enforcement, could combine
the EDR data with the type of pers onally identifying data routinely
acquired during a crash investigation.
To read data recorded by an ED R, special equipment is required,
and access to the vehicle or the EDR is needed. In addition to the
vehicle manufacturer, other parties, such as law enforcement, that
have the special equipment, can re ad the information if they have
access to the vehicle or the EDR.
The data belongs to the vehicle ow ner and may not be accessed by
anyone else except as legally requir ed or with the permission of the
vehicle owner.
Service Diagnostic Recorders
This vehicle is equipped with se rvice-related devices that record
information about powertrain perfo rmance. The data can be used
to verify emissions law requirem ents and/or help technicians
diagnose and solve service problems. It may also be combined with
data from other sources for res earch purposes, but it remains
confidential. Some diagnostic and maintenance information is
uploaded to Honda upon vehicle start up.

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 re gularly scheduled maintenance.
■Never let passengers ride in the pickup bed or inside a truck cap (shell).
They could be killed or injured in a cras h, or become ill or even die from carbon
monoxide poisoning if engine exhaust enters the cap.
■Do not leave children unattended in the vehicle
Children 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 which the children and/or another pers on(s) can be injured or killed. Also,
depending on the ambient temperature, th e temperature of the interior may reach
extreme levels, which can re sult in injury or death.
Even if the climate control system is on, never leave children 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, th e control unit and other related parts must be replaced.
Similarly, once an automatic seat belt tensioner 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 your dealer inspect the following: the driver’s
seat position sensor, weight sensors in the passenger’s seat, front seat belt
tensioners, and each seat belt that was worn during the crash.
■Do not remove or modify a front seat without cons ulting a dealer
This would likely disable or affect the proper operation of the driver’s seat position
sensor or the weight sensors in the passenger ’s seat. If it is necessary to remove or
modify a front seat to accommodate a pe rson with disabilities, contact a Honda
dealer, or for U.S. vehicles, American Honda Automobile Customer Service at
1-800-999-1009 and for Canadian vehicles, Honda Canada Customer Relations at
1-888-9-HONDA-9.
1 Airbag Care
We recommend against the use of salvaged airbag
system components, including the airbag, tensioners,
sensors, and control unit.
