Rear Climate Control System
If your vehicle has a rear climate-control system,
the rear-seat passengers can use it to adjust
the direction of the airow, the fan speed and
the temperature for the rear-seating area.
This system also works with the main
climate-control system in your vehicle.
The control panel for this system is located on the
back of the center console.If the AUX button located on the front climate
control panel is pressed, the rear climate control
system will be turned on. The rear system will
operate in automatic mode and the temperature
settings selected for the front climate control panel
will also be selected for the rear passengers.
If the rear passenger would like to adjust the
rear climate control system, they can select
a different temperature and a different mode
or fan speed.
Whenever the rear passengers have adjusted
settings on the rear climate control system,
the AUX light is lit on the front climate control
system. The driver can turn off the auxiliary fan
by pressing the AUX button.
When the front climate control system is turned
off or in defrost mode, the rear climate control
system is turned off. The rear system will turn
back on once another front mode is selected.
For more information on how to use the climate
control system, seeDual Climate Control System
on page 210. For more information on the air
outlets, seeOutlet Adjustment on page 217.

of the pollen from the air entering your vehicle.
Like your vehicle’s engine air cleaner/lter, it may

lter, seeScheduled Maintenance on page 465.
The access panel for the passenger compartment
air lter is located under the hood near the

cover with your ngers, you will not need a
tool for this step.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages on
your vehicle. The pictures help to locate them.
Warning lights and gages can signal that something
is wrong before it becomes serious enough to
cause an expensive repair or replacement. Paying
attention to the warning lights and gages could also
save you or others from injury.
Warning lights come on when there may be or is
a problem with one of your vehicle’s functions.
As the details show on the next few pages, some
warning lights come on briey when you start
the engine just to let you know they are working.
If you are familiar with this section, you should
not be alarmed when this happens.Gages can indicate when there may be or is a
problem with one of your vehicle’s functions.
Often gages and warning lights work together
to let you know when there is a problem with
your vehicle.
When one of the warning lights comes on and
stays on as you are driving, or when one of
the gages shows there may be a problem, check
the section that tells you what to do about it.
Please follow this manual’s advice. Waiting to
do repairs can be costly and even dangerous.
So please get to know your vehicle’s warning lights
and gages. They can be a big help.
Your vehicle may also have a Driver Information
Center (DIC) that works along with the warning
lights and gages. SeeDriver Information Center
(DIC) on page 240for more information.
222

Instrument Panel Cluster
The instrument panel cluster is designed to let you know at a glance how your vehicle is running. You will
know how fast you are going, how much fuel you are using and many of the other things you will need
to know to drive safely and economically.

Speedometer and Odometer
The speedometer lets you see your speed
in both miles per hour (mph) and kilometers
per hour (km/h). See “MPH (km)” underDIC
Controls and Displays on page 240for more
information.
The odometer mileage can be checked without
the vehicle running. Your vehicle’s odometer
works together with the driver information center.
You can set a Trip A and a Trip B odometer.
See “Trip Fuel” underDIC Controls and Displays
on page 240for more information.
If your vehicle ever needs a new odometer
installed, the new one will be set to the correct
mileage total of the old odometer.
Tachometer
This gage indicates
the engine speed in
revolutions per
minute (rpm).
