2007 CADILLAC XLR maintenance

Change the uid and lter at the intervals listed in
Additional Required Services on page 467, and
be sure to use the uid listed inRecommended
Fluids and Lubricants on page 473.
Engine Coolant
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is
designed to remain in your vehicle for ve years or
150,000 miles (240 000 km), whichever occurs
rst, if you add only DEX-COOL
®extended
life coolant.
The following explains your cooling system and
how to add coolant when it is low. If you have
a problem with engine overheating, seeEngine
Overheating on page 388.A 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant will:
Giving freezing protection down to−34°F
(−37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.
Notice:Using coolant other than DEX-COOL
®
may cause premature engine, heater core,
or radiator corrosion. In addition, the engine
coolant may require changing sooner, at
the rst maintenance service after each
30,000 miles (50 000 km) or 24 months,
whichever occurs rst. Any repairs would not
be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your
vehicle.

Brakes
Brake Fluid
Your brake master
cylinder reservoir is
lled with DOT-3 brake
uid. SeeEngine
Compartment Overview
on page 374for the
location of the reservoir.
There are only two reasons why the brake uid
level in the reservoir might go down. The rst
is that the brake uid goes down to an acceptable
level during normal brake lining wear. When
new linings are put in, the uid level goes back
up. The other reason is that uid is leaking out of
the brake system. If it is, you should have your
brake system xed, since a leak means that
sooner or later your brakes will not work well, or
will not work at all.So, it is not a good idea to top off your brake uid.
Adding brake uid will not correct a leak. If you
add uid when your linings are worn, then you will
have too much uid when you get new brake
linings. You should add or remove brake uid, as
necessary, only when work is done on the
brake hydraulic system.
{CAUTION:
If you have too much brake uid, it can
spill on the engine. The uid will burn if
the engine is hot enough. You or others
could be burned, and your vehicle could
be damaged. Add brake uid only when
work is done on the brake hydraulic
system. See “Checking Brake Fluid” in
this section.
Refer to the Maintenance Schedule to determine
when to check your brake uid. SeeScheduled
Maintenance on page 465.

Battery
Your vehicle has a maintenance free battery.
When it is time for a new battery, get one that has
the replacement number shown on the original
battery’s label. We recommend an ACDelco
®
replacement battery.
For battery replacement, see your dealer or the
service manual. To purchase a service manual,
seeService and Owner PublicationsinService
Publications Ordering Information on page 497.
Warning:Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive harm. Wash
hands after handling.
Vehicle Storage
If you are not going to drive your vehicle for 25 days
or more, remove the black, negative (−) cable from
the battery. This will help keep your battery from
running down.
{CAUTION:
Batteries have acid that can burn you and
gas that can explode. You can be badly
hurt if you are not careful. SeeJump
Starting on page 403for tips on working
around a battery without getting hurt.
You must close all doors and the trunk before
reconnecting the battery. After reconnecting
the battery, you must press the unlock button on
the keyless access transmitter. Failure to
follow this procedure may result in the alarm
sounding. Pressing unlock on the keyless access
transmitter would stop the alarm.

Bulb Replacement
It is recommended that all bulbs be replaced by
your dealer.
Windshield Replacement
Keep in mind that your windshield is part of the
Head-Up Display (HUD) system. If you ever have
to get your windshield replaced, be sure to get
one that is designed for HUD or your HUD image
may look blurred or out of focus.
Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected for
wear or cracking. SeeScheduled Maintenance
on page 465.
It is a good idea to clean or replace the wiper
blade assembly on a regular basis or when worn.
For proper windshield wiper blade length and
type, seeNormal Maintenance Replacement Parts
on page 475.To replace the wiper blade assembly, do the
following:
1. Place the vehicle in accessory mode and turn
the wipers on. Position the wipers on the
windshield in the mid-wipe position. Then with
a door open, turn the vehicle off.
2. Tip the blade up and pull up on the tab to
release the wiper blade assembly.
3. To install, align the wiper blade with the loop
on the wiper blade assembly, and push up to
snap it into place.

Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-ination has not reached the level to
trigger illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the
system is not operating properly. The TPMS
malfunction indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will ash for approximately
one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the
malfunction exists.
When the malfunction indicator is illuminated, the
system may not be able to detect or signal low
tire pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS from
functioning properly. Always check the TPMS
malfunction telltale after replacing one or moretires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
A Tire and Loading Information label, attached to
your vehicle, shows the size of your vehicle’s
original equipment tires and the correct ination
pressure for your vehicle’s tires when they
are cold. SeeLoading Your Vehicle on page 354,
for an example of the Tire and Loading
Information label and its location on your vehicle.
Also seeInation - Tire Pressure on page 422
for additional information.
Your vehicle’s TPMS can warn you about a low
tire pressure condition but it does not replace
normal tire maintenance. SeeTire Inspection and
Rotation on page 426,When It Is Time for
New Tires on page 428, andTires on page 413.
Notice:Do not use a tire sealant if your
vehicle has Tire Pressure Monitors. The liquid
sealant can damage the tire pressure monitor
sensors.
425

Tires
To clean the tires, use a stiff brush with tire
cleaner.
Notice:Using petroleum-based tire dressing
products on your vehicle may damage the
paint nish and/or tires. When applying a tire
dressing, always wipe off any overspray
from all painted surfaces on your vehicle.
Sheet Metal Damage
If the vehicle is damaged and requires sheet metal
repair or replacement, make sure the body
repair shop applies anti-corrosion material to parts
repaired or replaced to restore corrosion
protection.
Original manufacturer replacement parts will
provide the corrosion protection while maintaining
the warranty.
Finish Damage
Any stone chips, fractures or deep scratches in
the nish should be repaired right away.
Minor chips and scratches can be repaired with
touch-up materials available from your dealer
or other service outlets. Larger areas of nish
damage can be corrected in your dealer’s body
and paint shop.
Underbody Maintenance
Chemicals used for ice and snow removal and
dust control can collect on the underbody. If these
are not removed, corrosion and rust can develop
on the underbody parts such as fuel lines,
frame, oor pan, and exhaust system even though
they have corrosion protection.
At least every spring, ush these materials from the
underbody with plain water. Clean any areas where
mud and debris can collect. Dirt packed in close
areas of the frame should be loosened before being
ushed. Your dealer or an underbody car washing
system can do this for you.
