again before the rst 10 minutes of engine running time
has expired, 10 minutes are added to the remaining
minutes. For example, if the lock button and then
the remote start buttons are pressed again after
ve minutes of the engine run time, 10 minutes are
added and you now have 15 minutes of engine running.
The added ten minutes are considered a second
remote vehicle start.
Once two remote starts or a single start with a time
extension have been used, the vehicle must be started
with the ignition key before you can use the remote
start feature again.
The remote vehicle start feature will not operate if the
key is in the ignition, the hood is not closed, or if there is
an emission control system malfunction.
The engine will turn off during a remote vehicle start if
the coolant temperature gets too high, or the oil pressure
is too low.Your vehicle was shipped from the factory with the
remote vehicle start system enabled. The system
may be disabled through the Driver Information
Center (DIC). See “REMOTE START” underDIC
Vehicle Customization on page 3-86for additional
information.
SeeEngine Exhaust on page 2-36for important safety
information when using remote start in a closed
garage.
Remote Start Ready
If your vehicle does not have the remote vehicle start
feature, it may have the remote start ready feature.
This feature allows your dealer/retailer to add the
manufacturer’s remote vehicle start feature. See your
dealer/retailer if you would like to add the manufacturer’s
remote vehicle start feature to your vehicle.

Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
might begin programs to inspect the emission control
equipment on the vehicle. Failure to pass this inspection
could prevent getting a vehicle registration.
Here are some things to know to help the vehicle pass
an inspection:
The vehicle will not pass this inspection if the check
engine light is on with the engine running, or if the
key is in ON/RUN and the light is not on.
The vehicle will not pass this inspection if the
OBD II (on-board diagnostic) system determines
that critical emission control systems have not been
completely diagnosed by the system. The vehicle
would be considered not ready for inspection.
This can happen if the battery has recently
been replaced or if the battery has run down.
The diagnostic system is designed to evaluate
critical emission control systems during normal
driving. This can take several days of routine driving.
If this has been done and the vehicle still does
not pass the inspection for lack of OBD II system
readiness, your dealer/retailer can prepare the
vehicle for inspection.
Oil Pressure Light
{CAUTION:
Do not keep driving if the oil pressure is low.
The engine can become so hot that it catches re.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.
Notice:Lack of proper engine oil maintenance
can damage the engine. The repairs would not be
covered by the vehicle warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.

This message displays when the Adaptive Cruise
Control (ACC) is engaged and you are pressing the
accelerator pedal enough to disable ACC automatic
braking. SeeAdaptive Cruise Control on page 3-19
for more information.
OIL PRESSURE LOW STOP ENGINE
Notice:If you drive your vehicle while the engine
oil pressure is low, severe engine damage may
occur. If a low oil pressure warning appears on
the instrument panel cluster and/or DIC, stop the
vehicle as soon as possible. Do not drive the vehicle
until the cause of the low oil pressure is corrected.
SeeEngine Oil on page 5-13for more information.
This message displays when the vehicle’s engine
oil pressure is low. The oil pressure light also appears
on the instrument panel cluster. SeeOil Pressure
Light on page 3-64.
A multiple chime sounds when this message is
displayed. SeeEngine Oil on page 5-13for more
information.
Stop the vehicle immediately, as engine damage can
result from driving a vehicle with low oil pressure.
Have the vehicle serviced by your dealer/retailer as
soon as possible when this message is displayed.
PARKING ASSIST OFF
If your vehicle has the Ultrasonic Front and Rear
Parking Assist (UFRPA) system, after the vehicle is
shifted out of P (Park), this message displays to remind
the driver that the UFRPA system has been turned off.
Press the set/reset button to acknowledge this message
and clear it from the DIC display. To turn the UFRPA
system back on, see “PARKING ASSIST” underDIC
Operation and Displays on page 3-68. SeeUltrasonic
Front and Rear Parking Assist (UFRPA) on page 2-42
for more information.

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 your eyes moving — scan the road ahead
and to the sides.
Check the rearview mirror and vehicle instruments
often.

Checking Engine Oil
It is a good idea to check the engine oil level at each
fuel ll. 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. See
Engine Compartment Overview on page 5-12for
the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If this is not done, the
oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towel
or cloth, then push it back in all the way. Remove it
again, keeping the tip down, and check the level.
