Restraint System Check
Checking the Restraint Systems
Safety Belts
Now and then, check the safety belt reminder light,
safety belts, buckles, latch plates, retractors, and
anchorages are all working properly.
Look for any other loose or damaged safety belt system
parts that might keep a safety belt system from doing its
job. See your dealer/retailer to have it repaired. Torn
or frayed safety belts may not protect you in a crash.
They can rip apart under impact forces. If a belt is torn
or frayed, get a new one right away.
Make sure the safety belt reminder light is working.
SeeSafety Belt Reminders on page 3-44for more
information.
Keep safety belts clean and dry. SeeCare of Safety
Belts on page 6-76.
Airbags
The airbag system does not need regularly scheduled
maintenance or replacement. Make sure the airbag
readiness light is working. SeeAirbag Readiness Light
on page 3-44for more information.
Notice:If an airbag covering is damaged, opened,
or broken, the airbag may not work properly.
Do not open or break the airbag coverings. If there
are any opened or broken airbag covers, have
the airbag covering and/or airbag module replaced.
For the location of the airbag modules, see
What Makes an Airbag Inflate? on page 1-43.

Warning Lights, Gages, and
Indicators
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention
to the warning lights and gages could prevent injury.
Warning lights come on when there may be or is
a problem with one of the vehicle’s functions. Some
warning lights come on briey when the engine is started
to indicate they are working.
Gages can indicate when there may be or is a problem
with one of the vehicle’s functions. Often gages and
warning lights work together to indicate a problem with
the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gages shows there
may be a problem, check the section that explains
what to do. Follow this manual’s advice. Waiting to
do repairs can be costly and even dangerous.

Engine Air Cleaner/Filter
SeeEngine Compartment Overview on page 6-12for
the location of the engine air cleaner/lters.
Notice:If you spray water into the engine air
cleaner/lter intake and water enters the engine air
cleaner/lter housing, you could damage your
vehicle’s engine. The repairs would not be covered
by your warranty. Do not spray water into the
engine air cleaner/lter intake and/or housing.
When to Inspect the Engine Air
Cleaner/Filters
Inspect the air cleaner/lters at the MaintenanceII
intervals and replace them at the rst oil change after
each 50,000 mile (80 000 km) interval. SeeScheduled
Maintenance on page 7-4for more information.
If you are driving in dusty/dirty conditions, inspect the
lters at each engine oil change.
How to Inspect the Engine Air
Cleaner/Filters
To inspect the air cleaner/lters, remove the lters from
the vehicle and lightly shake the lters to release loose
dust and dirt. If the lters remain caked with dirt, new
lters are required.To inspect or replace the lters:
1. Some XLR-V vehicles, have a single piece black
cover that snaps over the entire air cleaner
assembly. For vehicles with this cover, simply pull it’s
left/right sides toward the outside of the vehicle and
lift up to remove cover. Reinstall the cover when you
are nished inspecting/replacing the lters.
2. For vehicles that do not have a single piece black
cover, move the clasps on the top of the engine air
cleaner/lter cover forward to unlatch the cover.
3. Lift the front of the cover at an angle and remove.
This is necessary due to the four tabs located on
the rear of the cover.

Brakes
Brake Fluid
The brake master cylinder
reservoir is lled with
DOT-3 brake uid. See
Engine Compartment
Overview on page 6-12for
the location of the reservoir.
There are only two reasons why the brake uid level in
the reservoir might go down:
The brake uid level goes down because of normal
brake lining wear. When new linings are installed,
the uid level goes back up.
A uid leak in the brake hydraulic system can also
cause a low uid level. Have the brake hydraulic
system xed, since a leak means that sooner
or later the brakes will not work well.Do not top off the brake uid. Adding uid does not
correct a leak. If uid is added when the linings
are worn, there will be too much uid when new brake
linings are installed. Add or remove brake uid, as
necessary, only when work is done on the brake
hydraulic system.
{CAUTION:
If too much brake uid is added, it can spill on the
engine and burn, if the engine is hot enough. You
or others could be burned, and the 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 the brake uid. SeeScheduled Maintenance
on page 7-4.
6-32

Bulb Replacement
It is recommended that all bulbs be replaced by your
dealer/retailer.
Windshield Replacement
The windshield is part of the Head-Up Display (HUD)
system. If you ever have to get the windshield replaced,
get one that is designed for HUD or the HUD image
may look out of focus.
Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected for wear
and cracking. SeeScheduled Maintenance on page 7-4
for more information.
Replacement blades come in different types and are
removed in different ways. For proper type and length,
seeMaintenance Replacement Parts on page 7-13.To replace the windshield wiper blade assembly:
1. Lift the wiper arm away from the windshield.
