Using the Auxiliary Input Jack
Your radio system has an auxiliary input
jack located on the lower right side of the
faceplate. This is not an audio output; do
not plug a headphone set into the front
auxiliary input jack. You can however, con-
nect an external audio device such as an
iPod, laptop computer, MP3 player, CD
changer, or cassette tape player, etc. to the
auxiliary input jack for use as another
source for audio listening.
The auxiliary input jack will also accept cell
phone connectors. Plug the cell phone
connector into the auxiliary input jack to
hear the other side of a cell phone’s con-
versation through the vehicle sound sys-
tem.
Drivers are encouraged to set up their por-
table audio player while the vehicle isparked. See Defensive Driving for more
information on driver distraction.
To use a portable audio player, connect a
3.5 mm (1/8 inch) cable to the radio’s front
auxiliary input jack. When a device is con-
nected, press the radio CD/AUX button as
needed to begin playing audio from the
device over the car speakers.
CD/AUX (CD/Auxiliary) button (9):
Press this button once to play a CD while a
portable audio device is playing. Press this
button a second time and the system will
begin playing audio from the connected
portable audio player. Once in this mode,
“Auxinput” will appear on the display. If the
auxiliary jack does not detect the presence
of an output jack, the aux mode will be pre-
vented from coming up.
Power/Volume knob (1):
Turn this knob clockwise or counterclock-
wise to increase or decrease the volume of
the portable player. You may need to make
additional volume adjustments from the
portable device if the volume does not go
loud or soft enough.

CD Messages
CHECK CD:
If this message appears on the display
and/or the CD comes out, it could be for
one of the following reasons:
 It is very hot. When the temperature
returns to normal, the CD will play.
 You are driving on a very rough road.
When the road becomes smoother, the
CD will play.
 The CD is dirty, scratched, wet, or
upside down.
 The air is very humid. If so, wait about an
hour and try again.
 The format of the CD may not be com-
patible. See “MP3/WMA Format” earlier
in this section.
 There may have been a problem while
burning the CD.
 The label may be caught in the CD
player.
If the CD is not playing correctly, for any
other reason, try a known good CD.
If any error occurs repeatedly or if an error
cannot be corrected, contact your SUZUKI
dealer. If the radio displays an error mes-
sage, write it down and provide it to your
SUZUKI dealer when reporting the prob-
lem.AUX Mod e

AdditivesTo provide cleaner air, all gasolines in the
United States are now required to contain
additives that will help prevent engine and
fuel system deposits from forming, allow-
ing your emission control system to work
properly. You should not have to add any-
thing to your fuel. However, some gaso-
lines contain only the minimum amount of
additive required to meet U.S. Environ-
mental Protection Agency regulations.
SUZUKI recommends that you buy gaso-
lines that are advertised to help keep fuel
injectors and intake valves clean. If your
vehicle experiences problems due to dirty
injectors or valves, try a different brand of
gasoline.
Gasoline containing oxygenates, such as
ethers and ethanol, and reformulated gas-
olines may be available in your area to
contribute to clean air. SUZUKI recom-
mends that you use these gasolines.
Some gasolines that are not reformulated
for low emissions may contain an octane-
enhancing additive called methylcyclopen-tadienyl manganese tricarbonyl (MMT);
ask the attendant where you buy gasoline
whether the fuel contains MMT. SUZUKI
does not recommend the use of such gas-
olines. Fuels containing MMT can reduce
the life of spark plugs and the performance
of the emission control system may be
affected. The malfunction indicator lamp
may turn on. If this occurs, return to your
SUZUKI dealer for service.
Fuels in Foreign CountriesIf you plan on driving in another country
outside the United States or Canada, the
proper fuel may be hard to find. Never use
leaded gasoline or any other fuel not rec-
ommended in the previous text on fuel.
Costly repairs caused by use of improper
fuel wouldn’t be covered by your warranty.
To check the fuel availability, ask an auto
club, or contact a major oil company that
does business in the country where you’ll
be driving.
Filling Your Tank
CAUTION
Your vehicle was not designed for
fuel that contains methanol. Don’t
use fuel containing methanol. It can
corrode metal parts in your fuel sys-
tem and also damage the plastic and
rubber parts. That damage wouldn’t
be covered under your warranty.
WARNING
Fuel vapor burns violently and a fuel
fire can cause severe injuries. To help
avoid injuries to you and others, read
and follow all the instructions on the
pump island. Turn off your engine
when you are refueling. Don’t smoke
if you’re near fuel or are refueling
your vehicle. Keep sparks, flames
and smoking materials away from
fuel. Don’t leave the fuel pump unat-
tended when refueling your vehicle –
this is against the law in some
places. Keep children away from the
fuel pump; never let children pump
fuel.

2) Get the vehicles close enough so the
jumper cables can reach, but be sure
the vehicles aren’t touching each other.
If they are, it could cause a ground con-
nection you don’t want. You wouldn’t be
able to start your vehicle, and the bad
grounding could damage the electrical
systems.
To avoid the possibility of the vehicles
rolling, set the parking brake firmly on
both vehicles involved in the jump start
procedure. Put an automatic transmis-
sion in PARK (P) or a manual transmis-
sion in NEUTRAL before setting the
parking brake.3) Turn off the ignition on both vehicles.
Unplug unnecessary accessories
plugged into the cigarette lighter or in
the accessory power outlet. Turn off the
radio and all lamps that aren’t needed.
This will avoid sparks and help save
both batteries. And it could save your
radio!
4) Open the hoods and locate the batter-
ies. Find the positive (+) and negative
(–) terminal locations on each vehicle.
Your vehicle’s positive (+) terminal is
located under a red tethered cap on the
battery. The negative (–) terminal is
located under a black tethered cap on
the battery. See “Engine Compartment
Overview” in this section for more infor-
mation on location. Flip the caps up to
access the positive (+) and negative (–)
terminals.
5) Check that the jumper cables don’t
have loose or missing insulation. If they
do, you could get a shock. The vehicles
could be damaged, too.
Before you connect the cables, here are
some basic things you should know.
Positive (+) will go to positive (+) or to a
remote positive (+) terminal if the vehi-
cle has one. Negative (–) will go to a
heavy, unpainted metal engine part or
to a remote negative (–) terminal if the
vehicle with the dead battery has one.
Don’t connect positive (+) to negative
(–) or you’ll get a short that would dam-
CAUTION
If the other system isn’t a 12-volt sys-
tem with a negative ground, both
vehicles can be damaged. Only use
vehicles with 12-volt systems with
negative grounds to jump start your
vehicle.
CAUTION
If you leave your radio or other acces-
sories on during the jump starting
procedure, they could be damaged.
The repairs wouldn’t be covered by
your warranty. Always turn off your
radio and other accessories when
jump starting your vehicle.
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.
WARNING
Using a match near a battery can
cause battery gas to explode. People
have been hurt doing this, and some
have been blinded. Use a flashlight if
you need more light.
Be sure the battery has enough
water. You don’t need to add water to
the battery installed in your new vehi-
cle. But if a battery has filler caps, be
sure the right amount of fluid is
there. If it is low, add water to take
care of that first. If you don’t, explo-
sive gas could be present.
Battery fluid contains acid that can
burn you. Don’t get it on you. If you
accidentally get it in your eyes or on
your skin, flush the place with water
and get medical help immediately.
