Outside Manual Mirrors
If the vehicle has the manual outside mirrors, adjust
each outside mirror so that a little of the vehicle and the
area behind it can be seen while sitting in a comfortable,
driving position.
Both mirrors can be manually folded inward by pulling
them towards the vehicle. Push the mirrors away
from the vehicle, to the normal position, before driving.
Outside Power Mirrors
The vehicle may have this feature.
The control is located
on the driver’s door.Turn the knob counterclockwise or clockwise to adjust
the driver’s or passenger’s mirror so that you can see
a little of the side of your vehicle. After adjusting
the position of the mirrors, turn the knob to the center
position so that the mirrors cannot move.
If the travel position in any direction of the mirror is
reached, it will enter a ratcheting mode. This action is
harmless. It is a warning that the mirror can go no
further. To stop this action, back the mirror up by
moving the knob in the opposite direction.
Outside Curb View Assist Mirror
If the vehicle has this feature, the passenger’s outside
mirror will adjust to a preset tilt position while the vehicle
is in REVERSE (R) gear. Curb view assist may be
useful when you are parallel parking. The mirror
will return to normal position when the vehicle is shifted
out of REVERSE (R) gear. Automatic mirror movement
in either direction will follow a short delay.
You may be able to turn this feature on or off through
the Driver Information Center (DIC). SeeDIC Vehicle

The cruise light on the
instrument panel cluster
will come on when
the cruise control is
engaged.
Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This, of course, shuts
off the cruise control. But you don’t need to reset it.
Once you’re going about 25 mph (40 km/h) or more, you
can move the cruise control switch briey from on to
resume/accelerate.
You’ll go right back up to your chosen speed and stay
there.
If you hold the switch at resume/accelerate, the vehicle
will keep going faster until you release the switch or
apply the brake. So unless you want to go faster, don’t
hold the switch at resume/accelerate.
Increasing Speed While Using Cruise
Control
There are two ways to go to a higher speed:
Use the accelerator pedal to get to the higher
speed. Press the button at the end of the lever,
then release the button and the accelerator pedal.
You’ll now cruise at the higher speed.
Move the cruise switch from on to
resume/accelerate. Hold it there until you get up to
the speed you want, and then release the switch.
To increase your speed in very small amounts,
move the switch briey to resume/accelerate.
Each time you do this, your vehicle will go about
1 mph (1.6 km/h) faster.
Reducing Speed While Using Cruise
Control
Press in the set button at the end of the lever until
you reach the lower speed you want, then release it.
Each time you do this, you’ll go about 1 mph (1.6 km/h)
slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, your vehicle will
slow down to the cruise control speed you set earlier.

When AUTO is selected, the air conditioning
operation and air inlet mode will be automatically
controlled. The air conditioning compressor will run
when the outside temperature is over approximately
40°F (4°C). The air inlet will normally be set to
outside air. If it’s hot outside, the air inlet will
automatically switch to recirculate inside air to help
quickly cool down your vehicle.
2. Set the driver’s and passenger’s temperature.
To nd your comfort setting, start with a 72°F (22°C)
temperature setting and allow about 20 minutes
for the system to regulate. Turn the driver’s or
passenger’s side temperature knob to adjust the
temperature setting as necessary. If you choose the
temperature setting of 60°F (15°C), the system
will remain at the maximum cooling setting. If you
choose the temperature setting of 90°F (32°C),
the system will remain at the maximum heat setting.
Choosing either maximum setting may not cause
the vehicle to heat or cool any faster.
