Driver Shift Control (DSC)
Driver Shift Control (DSC) allows you to shift an
automatic transmission similar to a manual
transmission. To use the DSC feature:
1. Move the shift lever to the right from D (Drive) into the DSC area.
The vehicle will be in sport mode. It will remain in
sport mode if the shift lever is not moved forward
or rearward. Sport mode will shift the transmission
automatically but remain in a gear longer than
it would in D (Drive) based on braking and
acceleration.

J. Air Delivery Mode Control AUTO (Automatic):
The system automatically controls
the fan speed, air delivery, air conditioning and
recirculation modes in order to heat or cool the vehicle
to the desired temperature.
To place the system in automatic mode:
1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting, generally, between 21°C (70°F) and 27°C (80°F).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool
any faster. If the system is set at the warmest
temperature setting, the system will try to
continuously heat the vehicle and will not adjust
the system down as the vehicle warms up.
To avoid blowing cold air in cold weather, the
system delays turning on the fan until warm air is
available. The system starts out blowing air at the
floor, but can automatically change modes as
the vehicle warms up to maintain the chosen
temperature setting. The length of time needed for
warm up depends on the outside temperature and
the length of time that has elapsed since the
vehicle was last driven.
3. Wait for the system to regulate. This may take from 10 to 30 minutes. Then adjust the temperature,
if necessary.

Rear Climate Control System
The vehicle has a rear climate control system. The
base model includes air outlets in the rear of the center
console for cooling and under-seat air outlets for
heating. The temperature, amount of airflow, and the
air delivery mode is controlled automatically by the front
climate control system.
Some vehicles may have an optional climate control
panel for the rear passenger, located on the back of the
center console.

Indicator
9(Off) : Turns off the airflow to the rear seat
passengers. With the air delivery off there may be an
increase in the air rush sound of the front system.
Temperature Control: Turn clockwise or
counterclockwise to increase or decrease the
temperature.
Air Delivery Mode Control: Turn to change the
direction of the airflow for the rear seat passengers.
To change the current mode, select one of the following:
Y (Vent): Air is directed to the console outlets.
\ (Bi-Level): Air is directed to the console and the
floor outlets.
[ (Floor): Air is directed to the floor outlets.
The front climate control system automatically controls
the amount of airflow to the rear seat passengers,
regardless of optional equipment. Airflow to the rear
system turns off when defrost is selected on the front
climate control panel, in order to direct air to clear the
windshield.
z(Heated Seat): Press to turn on rear heated seats.
There are two buttons, each with three indicator lights,
located between the climate control knobs on the rear
climate control panel.
Keep the area under the front seats clear of any objects
so the air in the vehicle can circulate effectively.

while driving, there may be a problem with the cooling
system. Driving with engine coolant temperature light on
could cause the vehicle to overheat, see Overheated
Engine Protection Operating Mode
on page 6‑32. See
Engine Overheatingon page 6‑30and DIC Warnings
and Messageson page 4‑76for more information.
Engine Coolant Temperature Gauge
This gauge shows
the engine coolant
temperature.
It can be used to see when the engine has warmed
up and to make sure the cooling system is operating
properly. If the gauge pointer moves into the shaded
area, the engine coolant is too hot and the engine
coolant temperature warning light comes on. See
Engine Overheating
