California Proposition 65 Warning
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;
• 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. Howe ver, other parties, such as law
enforcement, could combine the  EDR data with the type of
personally identifying data r outinely acquired during a crash
investigation.
WARNING:  This product contains or emits 
chemicals known to the state of California to cause 
cancer and birth defects or other reproductive 
harm.
To read data recorded by an ED R, special equipment is required, 
and access to the vehicle or the ED R 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 serv ice-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.
California Perchlorate Contamination Prevention Act
The airbags, seat belt tensioners , and CR type batteries in this 
vehicle may contain perchlorate materials - special handling may 
apply. See  www.dtsc.ca.gov/hazardouswaste/perchlorate/

Safe Driving
For Safe Driving
The following pages explain your vehicle’s safety features and how to use them 
properly. The safety precautions below are ones that we consider to be among the 
most important.
Important Safety Precautions
■Always wear your seat belt
A seat belt is your best protection in all types of collisions. Airbags are designed to 
supplement seat belts, not replace them. So  even though your vehicle is equipped 
with airbags, make sure you and your passen gers always wear your seat belts, and 
wear them properly.
■Restrain all children
Children ages 12 and under should ride properly restrained in a back seat, not the 
front seat. Infants and small children shoul d be restrained in a child seat. Larger 
children should use a booster seat and a lap/ shoulder seat belt until they can use the 
belt properly without a booster seat.
■Be aware of airbag hazards
While airbags can save lives, they can caus e serious or fatal injuries to occupants 
who sit too close to them, or are not prop erly restrained. Infants, young children, 
and short adults are at the greatest risk.  Be sure to follow all instructions and 
warnings in this manual.
■Don’t drink and drive
Alcohol and driving don’t mix. Even one dr ink can reduce your ability to respond to 
changing conditions, and your reaction time gets worse with every additional drink. 
So don’t drink and drive, and don’t let  your friends drink and drive, either.
1Important Safety Precautions
Some states, provinces and  territories prohibit the use 
of cell phones other than  hands-free devices by the 
driver while driving.

uuAirbags uAirbag System Indicators
Safe Driving■When the passenger airbag off 
indicator comes on
The indicator comes on to alert you that the 
passenger’s front airbag  has been turned off.
This occurs when the weight sensors detect 
65 lbs (29 kg) or less, the weight of an infant 
or small child, on the seat.
Children under the age of 12 should always ride properly restrained in a back seat.
2 Child Safety P. 53
Objects placed on the seat can also  cause the indicator to come on.
If the front passenger seat is empty, the passenger’s front airbag  will not deploy and 
the indicator will not come on.
■Passenger Airbag Off Indicator1 Passenger Airbag Off Indicator
If the indicator comes on with no front passenger and 
no objects on the passenger’s  seat, or with an adult 
riding there, something may be interfering with the 
weight sensors, such as:
•An object hanging on the seat  or in the seat-back 
pocket.
•A child seat or other obj ect pressing against the 
rear of the seat-back.
•A rear passenger pushing or  pulling on the back of 
the front passe nger’s seat.
•The front seat or seat-back is forced back against 
an object on the seat or floor behind it.
•An object placed under th e front passenger’s seat.
If none of these conditions exist, have your vehicle 
checked by a dealer as soon as possible.
The passenger airbag off  indicator may come on and 
goes off repeatedly if the to tal weight on the seat is 
near the airbag cutoff threshold.

Controls
Climate Control System*
Using Automatic Climate Control
The automatic climate control system maintains the interior temperature you select. 
The system also selects the proper mix of heated or cooled air that will as quickly as 
possible, raise or lower the interior  temperature to your preference.
Use the system when the engine is running.
1. Press the  AUTO button.
2. Adjust the interior temperature using the driver’s side or passenger’s side 
temperature control switch.
3. Press the    ON/OFF button to cancel.1Using Automatic Climate Control
If any buttons are presse d while using the climate 
control system in auto, the function of the button 
that was pressed will take priority.
The  AUTO  indicator will go off, but functions 
unrelated to the button th at was pressed will be 
controlled automatically.
If ECON mode is selected, the fan may turn off.
To prevent cold air from bl owing in from outside, the 
fan may operate at low speed for a while after the 
AUTO  button has been pressed.
Once you have set the de sired temperature, do not 
use the temperature control switches more than 
necessary.
Doing so may delay the time it takes to reach the set 
temperature.
If the interior is very warm, you can cool it down 
more rapidly by partial ly opening the windows, 
turning the system on auto, and setting the 
temperature to low. Change the fresh mode to 
recirculation mode  until the temperature cools down.
When you set the temperature to the lower or upper 
limit,  Lo or  Hi is displayed.
Pressing the   ON/OFF  button switches the 
climate control system be tween on and off. When 
turned on, the system returns to your last selection.
