unlocking of the steering column does not work
properly, have the vehicle towed to a dealer for service.
PULL KEY
- WAIT 10 SEC (Manual Transmission
Only): If this message comes on, the steering column
lock system has detected a problem while engaging the
steering column lock. This message may occur when
the ignition key is removed and reinserted before the
steering column lock system fully locks or unlocks the
steering column. To acknowledge that you have read
this message, and to clear it from the display, remove
the ignition key and wait 10 seconds before reinserting
the key into the ignition. If you attempt to operate
your vehicle without removing the key for 10 seconds,
the vehicle's fuel system will shut off when you reach
1.5 mph (2.4 km/h). If the message stays on after
removing the key and waiting 10 seconds, have your
vehicle taken to an authorized dealer as soon as possible
for diagnosis and repair.LOW OIL PRESSURE: You will hear four chimes
and the CHECK GAGES telltale will come on when
this message is displayed. To acknowledge the warning,
press the RESET button. After you press the RESET
button, a message will be displayed and you will hear a
chime every minute until the vehicle is serviced. If you
do not press RESET, the message will remain on the
digital display until the vehicle is serviced.
Low oil pressure may be the result of a combination
of low oil level and abrupt changes in the vehicle's
direction. When this warning is displayed, you should
not operate the engine at high rpm or make fast abrupt
moves. As soon as possible, you should check the oil
level. See ªEngine Oilº in the Index.
LOW OIL LEVEL: Press RESET to acknowledge
that you have read the message and to remove it from
the display. The message will reappear every 10 minutes
until this condition changes. Once the vehicle senses
a temperature change in the engine oil, the light will
remain off.
You will hear two chimes when this message is
displayed. If this message appears after starting your
engine, your engine oil level may be too low. You may
need to add oil. See ªEngine Overheatingº in the Index.

HIGH TRANS TEMP (Automatic Transmission
Only): You will hear four chimes when this message
is displayed. To acknowledge this warning, press the
RESET button. After you press the RESET button,
the message will be displayed every 10 minutes until
the condition changes. If you do not press RESET,
the message remains on the display until the
condition changes.
If the transmission fluid temperature rises above 270
F
(132
C) or rises rapidly, this message is displayed.
The transmission may shift gears or apply the torque
converter clutch to reduce the fluid temperature.
Driving aggressively or driving on long hills can cause
the transmission fluid temperature to be higher than
normal. If this message appears, you may continue to
drive at a slower speed. You should also monitor the
transmission fluid temperature and allow it to cool to at
least 230
F (110
C). The transmission fluid temperature
can be monitored with the GAGES button on the DIC.
See ªAutomatic Transmission Fluidº in the Index.
You should also check the engine coolant temperature.
If it is also hot, see ªEngine Overheatingº in the Index.If the HIGH TRANS TEMP message is displayed during
normal vehicle operation on flat roads, your vehicle may
need service. See your dealer for an inspection.
SERVICE ACTIVE HANDLING: If the SERVICE
ACTIVE HNDLG message is displayed, there is a
problem with your Active Handling System and your
vehicle needs service. The instrument cluster light will
also be on and a chime will sound. When this message
is displayed, the system is not working. Adjust your
driving accordingly.

Head-Up Display (HUD) (If Equipped)
CAUTION:
If the HUD image is too bright, or too high in
your field of view, it may take you more time to
see things you need to see when it's dark outside.
Be sure to keep the HUD image dim and placed
low in your field of view.
If your vehicle is equipped with the Head-Up Display
(HUD), you can see some of the driver information that
appears on your instrument panel cluster.The information may be displayed in English or metric
units and appears as an image focused out toward
the front of your vehicle. The HUD consists of the
following information:

Speedometer

Turn Signal Indicators

High
-Beam Indicator Symbol

Tachometer

Oil, Temperature and Fuel Gages

Shift Light (Performance SHIFT Light)
This light is used for performance driving to indicate
that the vehicle's best performance level has been
reached to shift the transmission into the next
higher gear. The SHIFT light will display at an
engine speed of about 5,750 rpm (6,250 rpm
on Z06), just prior to reaching the engine fuel
cut
-off mode. To better understand the vehicle's
power curves, see ªCapacities and Specificationsº

Hill and Mountain Roads
Driving on steep hills or mountains is different from
driving in flat or rolling terrain.If you drive regularly in steep country, or if you're
planning to visit there, here are some tips that can
make your trips safer and more enjoyable.

Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system
and transmission. These parts can work hard on
mountain roads.

Know how to go down hills. The most important
thing to know is this: let your engine do some of
the slowing down. Shift to a lower gear when you
go down a steep or long hill.
CAUTION:
If you don't shift down, your brakes could get so
hot that they wouldn't work well. You would then
have poor braking or even none going down a hill.
You could crash. Shift down to let your engine
assist your brakes on a steep downhill slope.
