2007 CADILLAC XLR service reset

If you get the overheat warning with no sign of
steam, try this for a minute or so:
1. In heavy traffic, let the engine idle in
NEUTRAL (N) while stopped. If it is safe to do
so, pull off the road, shift to PARK (P) or
NEUTRAL (N) and let the engine idle.
2. Set the climate controls to the highest heat
setting and fan speed and open the windows
as necessary.
If you no longer have the overheat warning, you
can drive. Just to be safe, drive slower for
about 10 minutes. If the warning does not come
back on, you can drive normally.
If the warning continues, pull over, stop, and park
your vehicle right away.
If there is still no sign of steam, idle the engine for
three minutes while you are parked. If you still
have the warning, turn off the engine and
get everyone out of the vehicle until it cools down.
Also, see “Overheated Engine Protection
Operating Mode” later in this section.
You may decide not to lift the hood but to get
service help right away.Overheated Engine Protection
Operating Mode
This operating mode allows your vehicle to be
driven to a safe place in an emergency situation. If
an overheated engine condition exists and the
DIC message ENGINE HOT, STOP ENGINE is
displayed, an overheat protection mode which
alternates ring groups of cylinders helps prevent
engine damage. In this mode, you will notice a
signicant loss in power and engine performance.
Driving extended miles (km) in the overheat
protection mode should be avoided.
Notice:After driving in the overheated engine
protection operating mode, to avoid engine
damage, allow the engine to cool before
attempting any repair. The engine oil will be
severely degraded. Repair the cause of coolant
loss, change the oil and reset the oil life
system. SeeEngine Oil on page 377.

What to Use
To add lubricant when the level is low, use
SAE 75W–90 Synthetic Gear Lubricant
(GM Part No. 89021677) or equivalent meeting
GM Specication 9986115. To completely
rell after draining, add 4 ounces (118 ml) of
Limited-Slip Differential Lubricant Additive
(GM Part No. 1052358) or equivalent. Then ll to
the bottom of the ller plug hole with the
Synthetic Gear Lubricant.
Headlamp Aiming
Your vehicle has high intensity discharge (HID)
visual optical aiming type headlamps. The aim has
been preset at the factory and should need no
further adjustment. If you suspect that the
headlamps need to be reaimed, it is recommended
that you contact your dealer for service. However,
it is possible for you to re-aim your headlamps
as described in the following procedure.
Notice:To make sure your headlamps are
aimed properly, read all the instructions before
beginning. Failure to follow these instructions
could cause damage to headlamp parts.

When rotating P235/50R18 size tires, always use
the correct rotation pattern shown here.
After the tires have been rotated, adjust the front
and rear ination pressures as shown on the Tire
and Loading Information label, seeInation - Tire
Pressure on page 422andLoading Your Vehicle on
page 354. Vehicles that have the Tire Pressure
Monitor (TPM) system will need to have the sensors
reset after a tire rotation is performed. A special tool
is needed to reset the sensor identication codes.
See your dealer for service. Make certain that all
wheel nuts are properly tightened. SeeWheel
Replacement on page 432and “Wheel Nut Torque”
underCapacities and Specications on page 458.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after a time. The wheel
could come off and cause a crash. When
you change a wheel, remove any rust or
dirt from places where the wheel attaches
to the vehicle. In an emergency, you can
use a cloth or a paper towel to do this;
but be sure to use a scraper or wire brush
later, if you need to, to get all the rust or
dirt off.
XLR-V Tires
Tire rotation is not recommended if your vehicle
has P235/45R19 size tires on the front axle
and P255/40R19 size tires on the rear axle.
Different tire sizes front to rear should not
be rotated.

Scheduled Maintenance
When the CHANGE OIL NOW message in the
Driver Information Center (DIC) comes on, it
means that service is required for your vehicle.
Have your vehicle serviced as soon as possible
within the next 600 miles (1 000 km). It is possible
that, if you are driving under the best conditions,
the engine oil life system may not indicate
that vehicle service is necessary for over a year.
However, your engine oil and lter must be
changed at least once a year and at this time the
system must be reset. Your GM Goodwrench
®
dealer has GM-trained service technicians who will
perform this work using genuine GM parts and
reset the system.If the engine oil life system is ever reset
accidentally, you must service your vehicle within
3,000 miles (5 000 km) since your last service.
Remember to reset the oil life system whenever
the oil is changed. SeeEngine Oil Life System on
page 380for information on the Engine Oil Life
System and resetting the system.
When the CHANGE OIL NOW message appears,
certain services, checks, and inspections are
required. Required services are described in the
following for “MaintenanceI” and “MaintenanceII.”
Generally, it is recommended that your rst
service be MaintenanceI, your second service be
MaintenanceII, and that you alternate
MaintenanceIand MaintenanceIIthereafter.
However, in some cases, MaintenanceIImay be
required more often.

MaintenanceI— Use MaintenanceIif the
CHANGE OIL NOW message comes on within
10 months since the vehicle was purchased
or MaintenanceIIwas performed.MaintenanceII— Use MaintenanceIIif the
