messages that may have been sent at the same time,
press the RESET button. If a tire pressure message
appears on the DIC, stop as soon as you can. Have the
tire pressures checked and set to those shown on the
Tire Loading Information label. SeeRun-Flat Tires
on page 5-64,Loading the Vehicle on page 4-24,
Inflation - Tire Pressure on page 5-66, andTire Pressure
Monitor System on page 5-68. The DIC also shows
the tire pressure values. SeeDIC Operation and
Displays on page 3-52.
To acknowledge the message, press the RESET button.
A message reappears every 10 minutes until the
condition is corrected.
HOT ENGINE AIR CONDITIONING OFF
This message displays when the engine coolant

Rell the fuel tank as soon as possible. SeeFuel Gage
on page 3-50.
LOW OIL PRESSURE
This message displays if low oil pressure levels occur.
If this message appears while the engine is running,
stop the engine and do not operate it until the cause of
low oil pressure is corrected. Severe damage to the
engine can result. A multiple chime sounds when this
message is displayed. SeeEngine Oil on page 5-17.

must be serviced. See your dealer/retailer. If a fault is
present in the Selective Ride Control system which
causes the shocks to be in their full soft condition,
the messages SERVICE RIDE CONTROL, SHOCKS
INOPERATIVE, and MAXIMUM SPEED 80 MPH
(129 km/h) will display together. SeeSelective Ride
Control on page 4-10for more information.
SERVICE TIRE MONITOR
This message displays if a part on the Tire Pressure
Monitor System (TPMS) is not working properly. The tire
pressure light also ashes and then remains on during
the same ignition cycle. SeeTire Pressure Light on
page 3-44. Several conditions may cause this message
to appear. SeeTire Pressure Monitor Operation on
page 5-70for more information. If the warning comes on
and stays on, there may be a problem with the TPMS.
See your dealer/retailer.

Before Leaving on a Long Trip
To prepare your vehicle for a long trip, consider having
it serviced by your dealer/retailer before departing.
Things to check on your own include:
Windshield Washer Fluid:Reservoir full? Windows
clean — inside and outside?
Wiper Blades:In good shape?
Fuel, Engine Oil, Other Fluids:All levels checked?
Lamps:Do they all work and are lenses clean?
Tires:Are treads good? Are tires inated to
recommended pressure?
Weather and Maps:Safe to travel? Have
up-to-date maps?
Highway Hypnosis
Always be alert and pay attention to your surroundings
while driving. If you become tired or sleepy, nd a
safe place to park your vehicle and rest.
Other driving tips include:
Keep the vehicle well ventilated.
Keep interior temperature cool.

Check the rearview mirror and vehicle instruments
often.
Hill and Mountain Roads
Driving on steep hills or through mountains is different
than driving on at or rolling terrain. Tips for driving
in these conditions include:
Keep the vehicle serviced and in good shape.
Check all uid levels and brakes, tires, cooling
system, and transmission.
Going down steep or long hills, shift to a
lower gear.

Checking Engine Oil (Except Z06)
If the CHECK OIL LEVEL message on the Driver
Information Center (DIC) comes on, check the engine
oil level right away. For more information, seeDriver
Information Center (DIC) on page 3-51. You should
check the engine oil level regularly; this is an added
reminder.
It is a good idea to check the engine oil level every time
you get fuel. In order to get an accurate reading, the
oil must be warm and the vehicle must be on level
ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 5-14
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil a few minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a lint-free
paper towel or a cloth, then push it back in all
the way.
3. Remove the dipstick again, keeping the tip down
and read the level on the cross-hatched area. Oil
levels that fall in the cross-hatched area are normal.
4. Push the dipstick back in all the way.
