trunk release handle located inside the
trunk on the underside of the trunk lid. This
handle will glow following exposure to light.
The trunk can be opened from the inside
by pulling the release handle down.
WARNING
It can be dangerous to drive with the
trunk lid open because carbon mon-
oxide (CO) gas can come into your
vehicle. You can’t see or smell CO. It
can cause unconsciousness and
even death. If you must drive with the
trunk lid open or if electrical wiring or
other cable connections must pass
through the seal between the body
and the trunk lid:
 Make sure all other windows are
shut.
 Turn the fan on your heating or
cooling system to its highest speed
and select the control setting that
will force outside air into your vehi-
cle. See “Climate Control System”
in the Index.
 If you have air outlets on or under
the instrument panel, open them all
the way.
See “Engine Exhaust” in the Index.
WARNING
Never operate the remote trunk
release button while your vehicle is
moving. An open trunk lid obscures
your rear view. That can result in a
collision causing damage to your
vehicle or other property, personal
injury, or even death.
N4U2009A
CAUTION
The emergency trunk release handle
is not designed to be used to tie
down the trunk lid or as an anchor
point when securing items in the
trunk. Improper use of the emergency
trunk release handle could damage it.

Theft-Deterrent SystemsVehicle theft is big business, especially in
some cities. Although your vehicle has a
number of theft-deterrent features, we
know that nothing we put on it can make it
impossible to steal.Theft-Deterrent SystemYour vehicle may have a theft-deterrent
system.
Arming the System
To arm the system, do the following:
1) Turn the ignition switch to the LOCK
and remove the key from the ignition. If
the key is inserted in the ignition switch,
the transmitter will not operate the theft-
deterrent system.
2) Close the doors, the windows, the
hood, and the trunk. Make sure the win-
dows are closed, as the system can be
activated even if the windows are open.
3) Lock the doors using the remote key-
less entry transmitter. The transmitter
must be used to activate the theft-deter-
rent system.
– The LED on the transmitter will flash
once.
– All of the doors will lock.
– The hazard warning lamps will flash
once and the horn will chirp.
– The theft-deterrent mode will activate.– The security light (A) will flash once
every 0.8 seconds to indicate that the
theft-deterrent system is armed. The
security light is located on the driver’s
door lock.
To avoid activating the alarm by accident,
do the following:
 Lock the vehicle with the key or the man-
ual door lock after the doors are closed if
you don’t want to arm the theft-deterrent
system.
 Unlock the driver’s or passenger’s front
door with the key or use the remote key-
less entry transmitter. Pressing the
UNLOCK button on the remote keyless
entry transmitter disables the theft-deter-
rent system. Unlocking a door any other
way will activate the alarm when a door
or the trunk is opened.The theft-deterrent system will not arm
when you lock the doors using the key or
the manual door lock. It arms only when
you use the remote keyless entry transmit-
ter.
Disarming the System
To disarm the system, do the following:
 Unlock the driver’s or passenger’s front
door using the key, or
 Press the Unlock button on the transmit-
ter.
– The LED on the transmitter will flash
once.
– All of the doors will unlock.
– The hazard warning lamps will flash
twice.
– The theft-deterrent mode will deacti-
vate.
How the System Alarm is Activated
If a door or the trunk is opened without the
key or the remote keyless entry transmitter,
the horn will sound and the lamps will flash
for up to 30 seconds.
The theft-deterrent system won’t arm if you
lock the doors with the key or use the man-
ual door lock. It activates only if you use
the remote keyless entry transmitter.
If the door is not opened or if the engine is
not started within 30 seconds after disarm-
ing the system with the transmitter, all of
the doors will automatically lock and the
theft-deterrent mode will reactivate.

theft-deterrent system.
How to Detect a Tamper Condition
If the hazard lamps flash once when the
Lock or Unlock button on your transmitter
is pressed, that means the theft-security
system alarm was triggered while you
were away.
Daily Inspection ChecklistBefore Driving1) Make sure that windows, mirrors, lights
and reflectors are clean and unob-
structed.
2) Visually check the tires for the following
points:
– the depth of the tread groove
– abnormal wear, cracks and damage
– loose wheel nuts
– existence of foreign material such as
nails, stones, etc.
Refer to “Tires” in the “SERVICE AND
APPEARANCE CARE” section for details.
3) Look for oil or other fluid leaks.
NOTE:

 As you go over the top of a hill, be alert.
There could be something in your lane,
like a stalled car or an accident.
 You may see highway signs on moun-
tains that warn of special problems.
Examples are long grades, passing or
no-passing zones, a falling rocks area or
winding roads. Be alert to these and take
appropriate action.Winter DrivingHere are some tips for winter driving:
 Have your vehicle in good shape for win-
ter.
 You may want to put winter emergency
supplies in your trunk.Include an ice scraper, a small brush or
broom, a supply of windshield washer fluid,
a rag, some winter outer clothing, a small
shovel, a flashlight, a red cloth and a cou-
ple of reflective warning triangles. And, if
you will be driving under severe conditions,
include a small bag of sand, a piece of old
carpet or a couple of burlap bags to help
provide traction. Be sure you properly
secure these items in your vehicle.
Driving on Snow or Ice
Most of the time, those places where your
tires meet the road probably have good
traction.
However, if there is snow or ice between
your tires and the road, you can have a
very slippery situation. You’ll have a lot
less traction or “grip” and will need to be
very careful.Very cold snow or ice can be slick and hard
to drive on. But wet ice can be even more
trouble because it may offer the least trac-
tion of all. You can get wet ice when it’s
about freezing (32°F; 0°C) and freezing
rain begins to fall. Try to avoid driving on
wet ice until salt and sand crews can get
there.
Whatever the condition – smooth ice,
packed, blowing or loose snow – drive with
caution.
Accelerate gently. Try not to break the frag-
ile traction. If you accelerate too fast, the
drive wheels will spin and polish the sur-
face under the tires even more.
Unless you have an anti-lock braking sys-
tem, you’ll want to brake very gently, too. (If
you do have anti-lock, see “Braking” in this
section. This system improves your vehi-

Determining Compatibility of Tire and
Vehicle Load Limits
The tires on your vehicle, when they are
inflated to the recommended tire inflation
pressure, have a load-carrying capacity
that is greater than the load that will be onthe tires when the vehicle is at its GVWR
or GAWR limit. Never use replacement
tires that have a load-carrying capacity
less than the original tires on your vehicle.
Tire load-carrying capacity information is
molded into the tire sidewall typically
shown as “Max. Load”. Use of replacement
tires with a lower load-carrying capacity
than the original tires, or failure to keep the
tires inflated to recommended tire pres-
sure, may reduce the GVWR or GAWR
limit of your vehicle.
NOTE:
Use of replacement tires with a higher
load-carrying capacity than the original
tires, or using a tire inflation pressure
higher than the recommended tire inflation
pressure, will not increase the GVWR or
GAWR limit of your vehicle.
Towing a TrailerDo not use your vehicle to tow a trailer. The
vehicle is not designed or intended for
such use. Towing a trailer can adversely
affect handling, durability and fuel econ-
omy.
WARNING
Things you put inside your vehicle
can strike and injure people in a sud-
den stop or turn, or in a crash.
 Put things in the trunk or rear area
of your vehicle. In a trunk, put them
as far forward as you can. Try to
spread the weight evenly. If you
have fold-down rear seats, you’ll
find four anchors on the back wall
of your trunk. You can use these
anchors to tie down lighter loads.
They’re not strong enough for
heavy things, however, so put them
as far forward as you can in the
trunk or rear area.
 Never stack heavier things, like
suitcases, inside the vehicle so that
some of them are above the tops of
the seats.
 Don’t leave an unsecured child
restraint in your vehicle.
 When you carry something inside
the vehicle, secure it whenever you
can.
 Don’t leave a seat folded down
unless you need to.

Used Replacement Wheels
Tire Chains
If a Tire Goes FlatIt’s a unusual for a tire to “blowout” while
you’re driving, especially if you maintain
your tire properly. If air goes out of a tire,
it’s much more likely to leak out slowly. But
if you should ever have a “blowout”, here
are a few tips about what to expect and
what to do:
If a front tire fails, the flat tire will create a
drag that pulls the vehicle toward that side.
Take your foot off the accelerator pedal
and grip the steering wheel firmly. Steer to
maintain lane position, and then gently
brake to a stop well out of the traffic lane.A rear blowout, particularly on a curve,
acts much like a skid and may require the
same correction you’d use in a skid. In any
rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under
control by steering the way you want the
vehicle to go. It may be very bumpy and
noisy, but you can still steer. Gently brake
to a stop, well off the road if possible.
If a tire goes flat, the next part shows how
to use your jacking equipment to change a
flat tire safely.
Changing a Flat TireIf a tire goes flat, avoid further tire and
wheel damage by driving slowly to a level
place. Turn on your hazard warning flash-
ers.
CAUTION
The wrong wheel can also cause
problems with bearing life, brake
cooling, speedometer or odometer
calibration, headlamp aim, bumper
height, vehicle ground clearance and
tire or tire chain clearance to the
body and chassis.
WARNING
Putting a used wheel on your vehicle
is dangerous. You can’t know how it’s
been used or how far it’s been driven.
It could fail suddenly and cause a
crash. If you have to replace a wheel,
use a new SUZUKI original equip-
ment wheel.
CAUTION
Use tire chains only where legal and
only when you must. Use only SAE
class “S” type chains that are the
proper size for your tires. Install them
on the front tires and tighten them as
tightly as possible with the ends
securely fastened. Drive slowly and
follow the chain manufacturer’s
instructions. If you can hear the
chains contacting your vehicle, stop
and retighten them. If the contact
continues, slow down until it stops.
Driving too fast or spinning the
wheels with chains on will damage
your vehicle.
WARNING
Lifting a vehicle and getting under it
to do maintenance or repairs is dan-
gerous without the appropriate safety
equipment and training. The jack pro-
vided with your vehicle is designed
only for changing a flat tire. If it is
used for anything else, you or others
could be badly injured or killed if the
vehicle slips off the jack. Use the jack
provided with your vehicle only for
changing a flat tire.
