WIND BUFFETING

Wind buffeting can be described as the perception
of pressure on the ears or a helicopter-type sound in
the ears. Your vehicle may exhibit wind buffeting
with the windows down, or the sunroof (if equipped)
in certain open or partially open positions. This is a
normal occurrence and can be minimized. If the
buffeting occurs with the rear windows open, open
the front and rear windows together to minimize the
buffeting. If the buffeting occurs with the sunroof
open, adjust the sunroof opening to minimize the
buffeting or open any window.

Never leave children unattended in a vehicle,
or with access to an unlocked vehicle. Never
leave the key fob in or near the vehicle, or in a
location accessible to children. Do not leave
the Keyless Enter ‘n Go™ Ignition in the ACC or
ON/RUN position. Occupants, particularly
unattended children, can become entrapped
by the power sunroof while operating the
power sunroof switch. Such entrapment may
result in serious injury or death.
In a collision, there is a greater risk of being
thrown from a vehicle with an open sunroof.
You could also be seriously injured or killed.
Always fasten your seat belt properly and
make sure all passengers are also properly
secured.
Do not allow small children to operate the
sunroof. Never allow your fingers, other body
parts, or any object, to project through the
sunroof opening. Injury may result.

Express or Manual Open operation is initiated the
sunshade will automatically open to the half open
position prior to the sunroof opening.
Pinch Protect Feature
This feature will detect an obstruction in the
opening of the sunroof during Express Close
operation. If an obstruction in the path of the
sunroof is detected, the sunroof will automatically
retract. Remove the obstruction if this occurs.
NOTE:
If three consecutive sunroof close attempts result in
Pinch Protect reversals, Pinch Protect will disable
and the sunroof must be closed in Manual Mode.

Venting Sunroof
Push and release the Vent button within one half
second and the sunroof will open to the vent
position. This is called “Express Vent”, and it will
occur regardless of sunroof position. During

2. Engine Coolant Temperature
This gauge shows the engine coolant
temperature. The gauge pointer will likely
show higher temperatures when driving in
hot weather, up mountain grades, or in
heavy stop and go traffic. If the red Warning
Light turns on while driving, safely bring the
vehicle to a stop, and turn off the engine.
DO NOT operate the vehicle until the cause
is corrected. 3. Instrument Cluster Display
When the appropriate conditions exist, this
display shows the instrument cluster
display messages Ú
page 114.
The display always shows one of the main
menu items after ignition on.
4. Oil Pressure Gauge
The pointer should always indicate some oil
pressure when the engine is running. A
continuous high or low reading under
normal driving conditions may indicate a
lubrication system malfunction. Immediate
service should be obtained from an autho -
rized dealer.
5. Speedometer
Indicates vehicle speed.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized
dealer for service if your vehicle overheats
Ú page 423.
WARNING!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge
reads “H” pull over and stop the vehicle. Idle the
vehicle with the air conditioner turned off until
the pointer drops back into the normal range. If
the pointer remains on the “H”, turn the engine
off immediately and call an authorized dealer
for service.

6. Diesel Exhaust Fluid (DEF) Gauge
The DEF Gauge displays the actual level of
Diesel Exhaust Fluid in the DEF tank. DEF is
required to maintain normal vehicle opera -
tion and emissions compliance. If some -
thing is wrong with the gauge, a DEF
Warning Message or Malfunction Indicator
Light (MIL) will be displayed Ú page 125.
NOTE:
• The gauge may take up to five seconds to
update after adding a gallon or more of
Diesel Exhaust Fluid to the DEF tank.
If you have a fault related to the DEF
system, the gauge may not update to the
new level. See an authorized dealer for
service. • The DEF gauge may also not immediately
update after a refill if the temperature of
the DEF fluid is below 12°F (-11°C). The
DEF line heater will possibly warm up the
DEF fluid and allow the gauge to update
after a period of run time. Under very cold
conditions, it is possible that the gauge
may not reflect the new fill level for
several drives.
• Outside temperature can affect DEF consumption. In cold conditions, 12°F
(-11°C) and below, the DEF gauge needle
can stay on a fixed position and may not
move for extended periods of time. This is
a normal function of the system.
7. Fuel Gauge
The gauge shows the level of fuel in the fuel
tank when the ignition switch is in the ON/
RUN position.
The fuel pump symbol points to the
side of the vehicle where the fuel door
is located.

NOTE:
• The DEF tank on these vehicles is

a full reading even before the tank is completely full. To put it another way,
there’s additional storage capacity in the
tank above the Full mark that’s not repre

movement in the reading – even after
driving up to 2,000 miles (3,219 km) in
some cases.

Your vehicle will be equipped with an instrument
cluster display, which offers useful information to
the driver. With the ignition in the OFF mode,
opening/closing of a door will activate the display
for viewing, and display the total miles, or
kilometers, in the odometer. Your instrument
cluster display is designed to display important
information about your vehicle’s systems and
features. Using a driver interactive display located
on the instrument panel, your instrument cluster
display can show you how systems are working and
give you warnings when they are not. The steering
wheel mounted controls allow you to scroll through
the main menus and submenus. You can access
the specific information you want and make
selections and adjustments.
