age the battery and maybe other parts,
too. And don’t connect the negative (–)
cable to the negative (–) terminal on the
dead battery because this can cause
sparks.
6) Connect the red positive (+) cable to
the positive (+) terminal of the dead
battery. Use a remote positive (+) termi-
nal if the vehicle has one.7) Don’t let the other end touch metal.
Connect it to the positive (+) terminal of
the good battery. Use a remote positive
(+) terminal if the vehicle has one.
8) Now connect the black negative (–)
cable to the negative (–) terminal of the
good battery. Use a remote negative (–)
terminal if the vehicle has one.
Don’t let the other end touch anything
until the next step. The other end of the
negative (–) cable doesn’t go to the
dead battery. It goes to a heavy,
unpainted metal engine part or to a
remote negative (–) terminal on the
vehicle with the dead battery.
9) Connect the other end of the negative
(–) cable at least 18 inches (45 cm)
away from the dead battery, but not
near engine parts that move. The elec-trical connection is just as good there,
and the chance of sparks getting back
to the battery is much less.
10)Now start the vehicle with the good bat-
tery and run the engine for a while.
11)Try to start the vehicle that had the
dead battery. If it won’t start after a few
tries, it probably needs service.
WARNING
An electric fan under the hood can
start up and injure you even when the
engine is not running. Keep hands,
clothing and tools away from any
underhood electric fan.
CAUTION
Damage to your vehicle may result
from electrical shorting if jumper
cables are removed incorrectly. To
prevent electrical shorting, take care
that the cables don’t touch each
other or any other metal. The repairs
wouldn’t be covered by your war-
ranty.

Headlamp AimingIf your vehicle is damaged in an accident,
the headlamp aim may be affected. Aim
adjustment of the low beam may be neces-
sary if it is difficult to see lane markers, for
horizontal aim, or if oncoming drivers flash
their high beams at you, for vertical aim. If
you believe your headlamps need to be re-
aimed, we recommend that you take your
vehicle to the dealer for service. However,
it is possible for you to re-aim your head-
lamps by following the procedure in the
service manual for your vehicle.
Bulb ReplacementFor the type of bulb to use, see “Replace-
ment Bulbs” in this section. For any bulb
changing procedure not listed in this sec-
tion, contact your SUZUKI dealer.Halogen Bulbs
CAUTION
To make sure your headlamps are
aimed properly, read all the instruc-
tions before beginning. Failure to fol-
low these instructions could cause
damage to headlamp parts.
WARNING
Halogen bulbs have pressurized gas
inside and can burst if you drop or
scratch the bulb. You or others could
be injured. Be sure to read and follow

Windshield Wiper Blade
ReplacementWindshield wiper blades should be
inspected at least twice a year for wear or

different types and are removed in different
ways.
Here’s how to remove the Shepherd’s
Hook type:

TiresYour new vehicle comes with high-quality
tires made by a leading tire manufacturer.
If you ever have questions about your tire
warranty and where to obtain service, see
your SUZUKI Warranty booklet for details.
For additional information refer to the tire
manufacturer’s booklet included with your
vehicle’s Owner’s Manual.
Tire Sidewall LabelingUseful information about a tire is molded
into its sidewall. The examples below show
a typical passenger car tire and a spare
tire sidewall.
Passenger Car Tire Example
A. Tire Size
The tire size is a combination of let-
ters and numbers used to define a
particular tire’s width, height, aspect
ratio, construction type and service
description. See the “Tire Size” illus-
WARNING
Poorly maintained and improperly
used tires are dangerous.
 Overloading your tires can cause
overheating as a result of too much
friction. You could have an air-out
and a serious accident. See “Load-
ing Your Vehicle” in the Index.
 Under inflated tires pose the same
danger as overloaded tires. The
resulting accident could cause
serious injury. Check all tires fre-
quently to maintain the recom-
mended pressure. Tire pressure
should be checked when your tires
are cold.
 Overi nflated tires are more likely to
be cut, punctured or broken by a
sudden impact – such as when you
hit a pothole. Keep tires at the rec-
ommended pressure.
(Continued)
WARNING
(Continued)
 Worn, old tires can cause acci-
dents. If your tread is badly worn,
or if your tires have been damaged,
replace them.

tration later in this section for more
detail.
B. Department of Transportation (DOT)
Code
The Department of Transportation
(DOT) code indicates that the tire is in
compliance with the U.S. Department
of Transportation Motor Vehicle
Safety Standards.
C. Tire Identification Number (TIN)
The letters and numbers following the
DOT code are the Tire Identification
Number (TIN). The TIN shows the
manufacturer and plant code, tire size
and the date the tire was manufac-
tured. The TIN is molded on to both
sides of the tire, although only one
side may have the date of manufac-
ture.
D. Tire Ply Material
The type of cord and number of plies
in the sidewall and under the tread.
E. Uniform Tire Quality Grading (UTQG)
Tire manufacturers are required to
grade tires based on three perfor-
mance factors: treadwear, traction
and temperature resistance.
F. Maximum Cold Inflation Load Limit
Maximum load that can be carried
and the maximum pressure needed to
support that load.
G. Load Index and Speed Rating
The two- or three-digit number is the
tire’s load index, the maximum load a
tire can carry at the speed indicated
by its speed symbol at the maximuminflation pressure. The higher the
number is, the greater the load carry-
ing capacity. The letter symbol
denotes the speed at which a tire is
designed to be driven for extended
periods of time. (Ratings are listed
below.)
*The letters ZR may be used on tires with a
maximum speed capability over 149 mph
and will always be used on tires with a
maximum speed capability over 186 mph.Compact Spare Tire Example
A. Temporary Use Only Marking
The compact spare tire should not be
driven at speeds over 50 mph (80 km/
h). The compact spare tire is for
emergency use when a regular road
tire has lost air and gone flat. See
“Compact Spare Tire” and “If a Tire
Goes Flat” in this section.
B. Tire Ply Material
The type of cord and number of plies
in the sidewall and under the tread.
C. Tire Identification Number (TIN)
The Tire Identification Number (TIN)
shows the manufacturer and plant
code, tire size, and date the tire was
manufactured. The TIN is molded
onto both sides of the tire, although
only one side may have the date of
manufacture.
D. Maximum Cold Inflation Load Limit
