4-12 DRIVING YOUR VEHICLE
78J00-03E
The most important advice on freeway
driving is: Keep up with traffic and keep to
the right. Drive at the same speed most of
the other drivers are driving. Too-fast or
too-slow driving breaks a smooth traffic
flow. Treat the left lane on a freeway as a
passing lane.
At the entrance, there is usually a ramp
that leads to the freeway. If you have a
clear view of the freeway as you drive
along the entrance ramp, you should begin
to check traffic. Try to determine where you
expect to blend with the flow. Try to merge
into the gap at close to the prevailing
speed. Switch on your turn signal, check
your mirrors, and glance over your shoul-
der as often as necessary. Try to blend
smoothly with the traffic flow.
Once you are on the freeway, adjust your
speed to the posted limit or to the prevail-
ing rate if it is slower. Stay in the right lane
unless you want to pass.
Before changing lanes, check your mirrors.
Then use your turn signal.
Just before you leave the lane, glance
quickly over your shoulder to make sure
there is not another vehicle in your blind
spot.
Once you are moving on the freeway,
make certain you allow a reasonable fol-
lowing distance. Expect to move slightly
slower at night.When you want to leave the freeway, move
to the proper lane well in advance. If you
miss your exit, do not, under any circum-
stances, stop and back up. Drive on to the
next exit.
The exit ramp can be curved, sometimes
quite sharply. The exit speed is usually
posted.
Reduce your speed according to your
speedometer, not to your sense of motion.
After driving for any distance at higher
speeds, you may tend to think you are
going slower than you actually are.
Before Leaving on a Long TripMake sure you are ready. Try to be well
rested. If you must start when you are not
fresh – such as after a day’s work – do not
plan to make too many miles that first part
of the journey. Wear comfortable clothing
and shoes you can easily drive in.
Is your vehicle ready for a long trip? If you
keep it serviced and maintained, it is ready
to go. If it needs service, have it done
before starting out. Of course, you will find
experienced and able service experts in
dealerships all across North America.
They will be ready and willing to help if you
need it.Here are some things you can check
before a trip:
 Windshield Washer Fluid:
Is the reservoir full? Are all windows
clean inside and outside?
 Wiper Blades:
Are they in good shape?
 Fuel, Engine Oil, Other Fluids:
Have you checked all levels?
 Lamps:
Are they all working? Are the lenses
clean?
Tires:
They are vitally important to a safe, trou-
ble-free trip. Is the tread good enough for
long-distance driving? Are the tires all
inflated to the recommended pressure?
 Weather Forecasts:
What is the weather outlook along your
route? Should you delay your trip a short
time to avoid a major storm system?
 Maps:
Do you have up-to-date maps?
Highway HypnosisIs there actually such a condition as high-
way hypnosis? Or is it just plain falling
asleep at the wheel? Call it highway hyp-
nosis, lack of awareness, or whatever.
There is something about an easy stretch
of road with the same scenery, along with
the hum of the tires on the road, the drone
of the engine, and the rush of the wind
against the vehicle that can make you
sleepy. Do not let it happen to you! If it

vehicle has a traction system, you will want
to slow down and adjust your driving to the
road conditions. Under certain conditions,
you may want to turn the traction system
off, such as when driving through deep
snow and loose gravel, to help maintain
vehicle motion at lower speeds. Refer to
“Traction Control System (TCS)” and
“Electronic Stability Control” in this section.
The Anti-Lock Brake System (ABS)
improves your vehicle’s stability when you
make a hard stop on a slippery road. Even
though you have ABS, you will want to
begin stopping sooner than you would on
dry pavement. Refer to “Anti-Lock Brake
System (ABS)” in this section.
 Allow greater following distance on any
slippery road.
 Watch for slippery spots. The road might
be fine until you hit a spot that is covered
with ice. On an otherwise clear road, ice
patches may appear in shaded areas
where the sun cannot reach, such as
around clumps of trees, behind build-
ings, or under bridges. Sometimes the
surface of a curve or an overpass may
remain icy when the surrounding roads
are clear. If you see a patch of ice ahead
of you, brake before you are on it. Try not
to brake while you are actually on the
ice, and avoid sudden steering maneu-
vers.If You Are Caught in a Blizzard
If you are stopped by heavy snow, you
could be in a serious situation. You should
probably stay with your vehicle unless you
know for sure that you are near help and
you can hike through the snow. Here are
some things to do to summon help and
keep yourself and your passengers safe:
 Turn on your hazard flashers.
 Tie a red cloth to your vehicle to alert
police that you have been stopped by the
snow.
 Put on extra clothing or wrap a blanket
around you. If you do not have blankets
or extra clothing, make body insulators
from newspapers, burlap bags, rags,
floor mats – anything you can wrap
around yourself or tuck under your cloth-
ing to keep warm.
808411
You can run the engine to keep warm, but
be careful.
Run your engine only as long as you must.
This saves fuel. When you run the engine,
make it go a little faster than just idle. That
is, push the accelerator slightly. This uses
less fuel for the heat that you get and it
keeps the battery charged.
You will need a well-charged battery to
restart the vehicle, and possibly for signal-
ing later on with your headlamps. Let the
heater run for a while.
Then, shut the engine off and close the
window almost all the way to preserve the
heat. Start the engine again and repeat
this only when you feel really uncomfort-
WARNING
Snow can trap exhaust gases under
your vehicle. This can cause deadly
CO (carbon monoxide) gas to get
inside. CO could overcome you and
kill you. You cannot see it or smell it,
so you might not know it is in your
vehicle. Clear away snow from
around the base of your vehicle,
especially any that is blocking the
exhaust pipe. And check around
again from time to time to be sure
snow does not collect there.
Open a window just a little on the
side of the vehicle that is away from
the wind. This will help keep CO out.

5-2 SERVICE AND APPEARANCE CARE
78J00-03E
FuelUse of the recommended fuel is an impor-
tant part of the proper maintenance of your
vehicle. To help keep the engine clean and
maintain optimum vehicle performance, we
recommend the use of gasoline advertised
as TOP TIER Detergent Gasoline.Gasoline OctaneUse regular unleaded gasoline with a
posted octane rating of 87 or higher. If the
octane rating is less than 87, you may
notice an audible knocking noise when you
drive, commonly referred to as spark
knock. If this occurs, use a gasoline rated
at 87 octane or higher as soon as possible.
If you are using gasoline rated at 87
octane or higher and you hear heavy
knocking, your engine needs service.
Gasoline SpecificationsAt a minimum, gasoline should meet
ASTM specification D 4814 in the United
States or CAN/CGSB-3.5 in Canada.
Some gasolines contain an octane-
enhancing additive called methylcyclopen-
tadienyl manganese tricarbonyl (MMT).
We recommend against the use of gaso-
lines containing MMT. Refer to “Additives”
in this section for additional information.California FuelIf your vehicle is certified to meet California
Emissions Standards, it is designed to
operate on fuels that meet California spec-
ifications. See the underhood emission
control label. If this fuel is not available in
states adopting California emissions stan-
dards, your vehicle will operate satisfacto-
rily on fuels meeting federal specifications,
but emission control system performance
may be affected. The malfunction indicator
lamp may turn on and your vehicle may fail
a smog-check test. Refer to “Malfunction
Indicator Lamp” in “Warning Lights, Gages,
and Indicators” in the “Instrument Panel”
section. If this occurs, return to your autho-
rized dealer for diagnosis. If it is deter-
mined that the condition is caused by the
type of fuel used, repairs may not be cov-
ered by your warranty.
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. In most cases, you should not
have to add anything to your fuel. How-
ever, some gasolines contain only the min-
imum amount of additive required to meet
U.S. Environmental Protection Agency
regulations. To help keep fuel injectors and
intake valves clean, or if your vehicle expe-
riences problems due to dirty injectors or
valves, look for gasoline that is advertised
as TOP TIER Detergent Gasoline. Also,
your dealer has additives that will help cor-
rect and prevent most deposit-related
problems.
Gasolines containing oxygenates, such as
ethers and ethanol, and reformulated gas-
olines may be available in your area. We
recommend that you use these gasolines,
if they comply with the specifications
described earlier. However, E85 (85% eth-
anol) and other fuels containing more than
10% ethanol must not be used in vehicles
that were not designed for those fuels.

system to work properly, you must reset
the system every time the oil is changed.
When the system has calculated that oil
life has been diminished, it will indicate
that an oil change is necessary. A change
engine oil light and a CHANGE ENGINE
OIL SOON message will come on. Refer to
“Change Engine Oil Light” in “Warning
Lights, Gages, and Indicators” in the
“Instrument Panel” section and “DIC Warn-
ings and Messages” in “Driver Information
Center (DIC)” in the “Instrument Panel”
section. Change your oil as soon as possi-
ble within the next 600 miles (1000 km). It
is possible that, if you are driving under the
best conditions, the oil life system may not
indicate that an oil change is necessary for
over a year. However, your engine oil and
filter must be changed at least once a year
and at this time the system must be reset.
Your dealer has trained service people
who will perform this work and reset the
system. It is also important to check your
oil regularly and keep it at the proper level.
If the system is ever reset accidentally, you
must change your oil at 3000 miles (5000
km) since your last oil change. Remember
to reset the oil life system whenever the oil
is changed.
How to Reset the Engine Oil Life Sys-
tem
The Engine Oil Life System calculates
when to change your engine oil and filter
based on vehicle use. Anytime your oil ischanged, reset the system so it can calcu-
late when the next oil change is required. If
a situation occurs where you change your
oil prior to a change engine oil light or
CHANGE ENGINE OIL SOON message
being turned on, reset the system.
1) Turn the ignition key to RUN with the
engine off.
2) Fully press and release the accelerator
pedal three times within five seconds.
The change engine oil light will flash
while the system is resetting.
3) When the light stops flashing, turn the
key to LOCK.
If the light or message comes back on and
stays on when you start your vehicle, the
engine oil life system has not reset.
Repeat the procedure.
What to Do with Used Oil
Used engine oil contains certain elements
that may be unhealthy for your skin and
could even cause cancer. Do not let used
oil stay on your skin for very long. Clean
your skin and nails with soap and water, or
a good hand cleaner. Wash or properly
dispose of clothing or rags containing used
engine oil. See the manufacturer’s warn-
ings about the use and disposal of oil prod-
ucts.
Used oil can be a threat to the environ-
ment. If you change your own oil, be sure
to drain all the oil from the filter before dis-
posal. Never dispose of oil by putting it inthe trash, pouring it on the ground, into
sewers, or into streams or bodies of water.
Instead, recycle it by taking it to a place
that collects used oil. If you have a prob-
lem properly disposing of your used oil,
ask your dealer, a service station, or a
local recycling center for help.
Engine Air Cleaner/FilterThe engine air cleaner/filter is located in
the engine compartment on the passen-
ger’s side of the vehicle. Refer to “Engine
Compartment Overview” in this section for
more information on location.
When to Inspect the Engine Air Cleaner/
Filter
Inspect the air cleaner/filter at the Mainte-
nance II intervals and replace it at the first
oil change after each 50000 mile (83000
km) interval. Refer to “Scheduled Mainte-
nance” in “Maintenance Schedule” in the
“Maintenance Schedule” section for more
information. If you are driving in dusty/dirty
conditions, inspect the filter at each engine
oil change.
How to Inspect the Engine Air Cleaner/
Filter
To inspect the air cleaner/filter remove the
filter from the vehicle and lightly shake the
filter to release loose dust and dirt. If the fil-
ter remains caked with dirt, a new filter is
required.

If you have to add coolant more than four
times a year, have your dealer check your
cooling system.
Checking Coolant
1631523
The surge tank is located on the driver’s
side of the engine compartment. Refer to“Engine Compartment Overview” in this
section for more information on location.
The vehicle must be on a level surface.
When your engine is cold, the coolant level
should be at the COLD FILL line. When
your engine is warm, the level should be at
the COLD FILL line or a little higher.
Adding Coolant
If you need more coolant, add the proper
DEX-COOL
® coolant mixture at the surge
tank, but only when the engine is cool.
When replacing the pressure cap, make
sure it is hand-tight and fully seated.
Engine OverheatingThere is a coolant temperature gage and a
warning light on the instrument panel clus-
ter that indicate an overheated engine con-
dition. Refer to “Engine Coolant
Temperature Gage” and “Engine Coolant
Temperature Warning Light” in “Warning
Lights, Gages, and Indicators” in the
“Instrument Panel” section for more infor-
mation.
If Steam Is Coming From Your Engine
CAUTION
If you use extra inhibitors and/or
additives in your vehicle’s cooling
system, you could damage your vehi-
cle. Use only the proper mixture of
the engine coolant listed in this man-
ual for the cooling system. Refer to
“Recommended Fluids and Lubri-
cants” in “Maintenance Schedule” in
the “Maintenance Schedule” section
for more information.
WARNING
Turning the surge tank pressure cap
when the engine and radiator are hot
can allow steam and scalding liquids
to blow out and burn you badly.
Never turn the surge tank pressure
cap – even a little – when the engine
and radiator are hot.
WARNING
You can be burned if you spill cool-
ant on hot engine parts. Coolant con-
tains ethylene glycol, and it will burn
if the engine parts are hot enough. Do
not spill coolant on a hot engine.
WARNING
Steam from an overheated engine
can burn you badly, even if you just
open the hood. Stay away from the
engine if you see or hear steam com-
ing from it. Turn it off and get every-
one away from the vehicle until it
cools down. Wait until there is no
sign of steam or coolant before you
open the hood.
If you keep driving when the vehicles
engine is overheated, the liquids in it
can catch fire. You or others could be
badly burned. Stop your engine if it
overheats, and get out of the vehicle
until the engine is cool.
Refer to “Overheated Engine Protec-
tion Operating Mode” in this section
for information on driving to a safe
place in an emergency.

3) Turn off the ignition on both vehicles.
Unplug unnecessary accessories
plugged into the cigarette lighter or the
accessory power outlets. Turn off the
radio and all lamps that are not needed.
This will avoid sparks and help save
both batteries. And it could save the
radio!
4) Open the hood on the other vehicle and
locate the positive (+) and negative (–)
terminal locations on that vehicle.
You will not use your vehicle’s battery
for jump starting. It has a remote posi-
tive (+) jump starting terminal, located
on the underhood fuse block, for that
purpose. Refer to “Engine Compart-
ment Overview” in this section for more
information on location.

To uncover the remote positive (+) ter-
minal, press the tab at the bottom of thefuse block and lift the cover up.
Always use the remote positive (+) ter-
minal instead of the positive (+) termi-
nal on the battery.
5) Check that the jumper cables do not
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
vehicle has one. Negative will go to a
heavy, unpainted metal engine part or
to a remote negative (–) terminal if the
vehicle has one.
WARNING
An electric fan can start up even
when the engine is not running and
can injure you. Keep hands, clothing
and tools away from any underhood
electric fan.
WARNING
Fans or other moving engine parts
can injure you badly. Keep your
hands away from moving parts once
the engine is running.
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 do not need to add water
to the battery installed in your new
vehicle. 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 do not,
explosive gas could be present.
(Continued)
WARNING
(Continued)
Battery fluid contains acid that can
burn you. Do not 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.
CAUTION
If you connect a negative cable to the
Engine Control Module (ECM), ECM
mounting bracket or any cables that
attach to the ECM bracket, you may
damage the ECM. Attach the negative
cable to a heavy, unpainted metal
engine part, other than the ECM, ECM
bracket or cables attached to the
ECM bracket.

allow the TPMS to continue to function
properly.
When a low tire pressure condition is
detected, the TPMS will illuminate the low
tire pressure warning symbol on the instru-
ment panel cluster, and at the same time a
message to check the pressure in a spe-
cific tire will appear on the Driver Informa-
tion Center (DIC) display. The low tire
pressure warning symbol on the instru-
ment panel cluster and the check tire pres-
sure message will appear at each ignition
cycle until the tires are inflated to the cor-
rect inflation pressure. Using the DIC, tire
pressure levels can be viewed by the
driver. For additional information and
details about the DIC operation and dis-
plays refer to “DIC Operation and Dis-
plays” and “DIC Warnings and Messages”
in “Driver Information Center (DIC)” in the
“Instrument Panel” section.
The low tire pressure warning light may
come on in cool weather when the vehicle
is first started, and then turn off as you
start to drive. This may be an early indica-
tor that the air pressure in the tire(s) are
getting low and need to be inflated to the
proper pressure.
A Tire and Loading Information Label,
attached to your vehicle, shows the size of
your vehicle’s original equipment tires and
the correct inflation pressure for your vehi-
cle's tires when they are cold. Refer to
“Loading Your Vehicle” in “Your Driving,the Road, and Your Vehicle” in the “Driving
Your Vehicle” section, for an example of
the Tire and Loading Information Label
and its location on your vehicle. Also refer
to “Inflation - Tire Pressure” in this section.
Your vehicle’s TPMS system can warn you
about a low tire pressure condition but it
does not replace normal tire maintenance.
Refer to “Tire Inspection and Rotation” and
“Tires” in this section.
The TPMS will not function properly if one
or more of the TPMS sensors are missing
or inoperable. If the system detects a miss-
ing or inoperable sensor, an error mes-
sage SERVICE TIRE MONITOR SYSTEM
will be shown on the DIC display. If you
have replaced a tire/wheel assembly with-
out transferring the TPMS sensors, the
error message will be displayed. Once you
re-install the TPMS sensors, the error
message should go off. See your SUZUKI
dealer for service if all TPMS sensors are
installed and the error message comes on
and stays on.
TPMS Sensor Matching Process
Each TPMS sensor has a unique identifi-
cation code. Any time you replace one ormore of the TPMS sensors or rotate the
vehicle’s tires, the identification codes will
need to be matched to the new tire/wheel
position. The sensors are matched, to the
tire/wheel positions, in the following order:
driver side front tire, passenger side front
tire, passenger side rear tire, and driver
side rear tire using a TPMS diagnostic tool.
See your SUZUKI dealer for service.
The TPMS sensors may also be matched
to each tire/wheel position by increasing or
decreasing the tire’s air pressure. When
increasing the tire’s pressure, do not
exceed the maximum inflation pressure
indicated on the tire’s sidewall.
You will have two minutes to match each
tire and wheel position. If it takes longer
than two minutes to match any tire and
wheel position, the matching process
stops and you will need to start over.
The TPMS matching process is outlined
below:
1) Set the parking brake.
2) Turn the ignition switch to RUN with the
engine off.
3) Using the DIC, press the vehicle infor-
mation button until the TIRE LOCA-
TIONS PRESS TO LEARN message
displays.
4) Press the set/reset button to allow the
system to learn the tire positions. The
horn will sound twice to indicate the
receiver is ready, and the TIRE
LEARNING ACTIVE message displays.
CAUTION
Do not use a tire sealant if your vehi-
cle has Tire Pressure Monitors. The
liquid sealant can damage the tire
pressure monitor sensors.

6-2 MAINTENANCE SCHEDULE
78J00-03E
Some maintenance services can be com-
plex. So, unless you are technically quali-
fied and have the necessary equipment,
you should have your dealer do these jobs.
When you go to your dealer for your ser-
vice needs, you will know that trained and
supported service technicians will perform
the work using genuine parts.
“Owner Checks and Services” in this sec-
tion tells you what should be checked,
when to check it, and what you can easily
do to help keep your vehicle in good condi-
tion.
The proper replacement parts, fluids, and
lubricants to use are listed in “Recom-
mended Fluids and Lubricants” and “Nor-
mal Maintenance Replacement Parts” in
this section. When your vehicle is serviced,
make sure these are used. All parts should
be replaced and all necessary repairs
done before you or anyone else drives the
vehicle.
Scheduled MaintenanceWhen the change engine oil light and/or
CHANGE ENGINE OIL SOON message
comes on, it means that service is required
for your vehicle. Have your vehicle ser-
viced as soon as possible within the next
600 miles (1000 km). It is possible that, if
you are driving under the best conditions,
the engine oil life system may not indicate
that vehicle service is necessary for over a
year. However, the engine oil and filter
must be changed at least once a year (or
10 months if operated in Canada) and at
this time the system must be reset. Your
dealer has trained service technicians who
will perform this work using genuine parts
and reset the system.
If the engine oil life system is ever reset
accidentally, you must service your vehicle
within 3000 miles (5000 km) since your last
service. Remember to reset the oil life sys-
tem whenever the oil is changed. Refer to
“Engine Oil Life System” in “Checking
Things Under the Hood” in the “Service
and Appearance Care” section for informa-
tion on the Engine Oil Life System and
resetting the system.
For ALL except CANADA
When the change engine oil light and/or
CHANGE ENGINE OIL SOON message
appears, certain services, checks, and
inspections are required. Required ser-
vices are described in the following for
“Maintenance I” and “Maintenance II”.Generally, it is recommended that your first
service be Maintenance I, your second
service be Maintenance II, and that you
alternate Maintenance I and Maintenance
II thereafter. However, in some cases,
Maintenance II may be required more
often.
Maintenance I
Use Maintenance I if the light/message
comes on within 10 months since the vehi-
cle was purchased or Maintenance II was
performed.
Maintenance II
Use Maintenance II if the previous service
performed was Maintenance I. Always use
Maintenance II whenever the light/mes-
sage comes on 10 months or more since
the last service or if the light/message has
not come on at all for one year.
For CANADA
Use For CANADA Scheduled Maintenance
if the light/message comes on or if more
than 10 months have elapsed since the
most recent maintenance service was per-
formed.
