Using the 2WD/i-AWD
(intelligent All Wheel Drive)
Switch (if equipped)
80J009
This i-AWD system enables you to select
the driving mode according to the driving
conditions by operating the 2WD/i-AWD
switch. With this feature, you can select 3
mode positions, “2WD”, “i-AWD AUTO”
and “i-AWD LOCK” by operating the 2WD/
i-AWD switch even when the vehicle is
moving, provided the front wheels are in
the straight ahead position.Description of 3 Mode 4 x 4 System
Positions2WD
In this position, engine power is supplied to
the front axle only. Use this position for
normal driving (on dry, hard surfaces).i-AWD AUTO
In this position, engine power is supplied to
the front and rear axles at normal speed,
providing greater traction than 2-wheel
drive. Use this position for driving on paved
roads or on slippery roads (icy, snow-cov-
ered, muddy, etc.).
In the AUTO mode, the i-AWD controller
judges the driving conditions using signals
from sensors.
When slipping of the front wheels is
detected, the electronically controlled cou-
pling supplies optimum driving force to the
rear wheels. This function improves driving
stability and running through performance
on rough roads and stabilizes driving per-
formance even on a snow covered up-hill
road or the like.
Also, during normal driving on paved
roads, torque distribution to the rear
wheels is reduced to achieve the nearly
front wheel drive condition, thereby fuel
consumption is improved.
i-AWD LOCK
In this position, engine power is supplied to
the front and rear axles at reduced speed.
Use this position when it is hard to start off
in the “i-AWD AUTO” mode such as in
mud, sand or on snow.
NOTE:
 Avoid operating your vehicle in the “i-
AWD LOCK” on wet pavement as much
as possible. Operating your vehicle in
the “i-AWD LOCK” on wet pavementmay cause severe damage to the drive
train.
 As the vehicle speed increases, the “i-
AWD LOCK” mode is automatically can-
celed and the “i-AWD AUTO” mode is
selected.
 When the ignition switch is turned to the
“OFF” position, the “i-AWD LOCK” mode
is canceled.

You should turn the ESP
® on during your
ordinary driving, so that you have the ben-
efits of all of the ESP
® systems.
It may be required to turn the ESP
® sys-
tems (other than ABS) off if your vehicle is
stuck in sand, mud, or snow, where wheel
spin is necessary.“ESP OFF” switch

When the “ESP OFF” switch located at the
center console is pushed and held to turn
off the ESP
® systems (other than ABS),
the “ESP OFF” indicator light in the instru-
ment cluster comes on.
When you have turned the ESP
® systems
(other than ABS) off, make sure to turn
them back on before resuming ordinary
driving.
When you push the “ESP OFF” switch
again, the “ESP OFF” indicator light will go
out and all of the ESP
® systems will be

Warning LightSee “Braking” in the “OPERATING YOUR
VEHICLE” section.
Tire Pressure Monitoring
System (TPMS)The tire pressure monitoring system is
designed to alert you when one or more of
the tires on your vehicle is significantly
under-inflated. A Tire Pressure Monitoring
System (TPMS) sensor containing a
unique identification code is mounted on
each wheel. The TPMS sensors transmit
tire pressure signals to a central receiver
which relays the information to a tire pres-
sure monitoring system controller. When
the inflation pressure of one or more tires
indicates significant under-inflation, the low
tire pressure warning light shown below
comes on.
CAUTION
If the “ESP” warning light comes on,
or stays on while driving, there may
be a malfunction of the ESP
® sys-
tems (other than ABS). You should
have the systems inspected by an
authorized SUZUKI dealer.

TPMS Malfunction Indicator
When you turn off the engine, however, the
malfunction indicator resets. It takes about
ten minutes after restarting the engine for
the malfunction to be detected again and
for the light to start flashing.
TPMS LimitationsThe tire pressure monitoring system may
not function properly under certain circum-
stances. In the following situations, the low
tire pressure warning light may come on
and remain on or may blink.
 When you replace a flat tire with the
spare tire.
 When you include the spare tire during a
tire rotation.
 When the TPMS sensor is damaged dur-
ing a tire replacement or liquid sealants
are used to repair a flat tire.
WARNING
Your vehicle also has been equipped
with a TPMS malfunction indicator to
indicate when the system is not oper-
ating properly.
WARNING
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately one minute and then
remain continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups as long
as the malfunction exists.
WARNING
When the malfunction indicator is
illuminated, the system may not be
able to detect or signal low tire pres-
sure as intended. TPMS malfunctions
may occur for a variety of reasons,
including the installation of replace-
ment or alternate tires or wheels on
the vehicle that prevent the TPMS
from functioning properly. Always
check the TPMS malfunction telltale
after replacing one or more tires or
wheels on your vehicle to ensure that
the replacement or alternate tires and
wheels allow the TPMS to continue to
function properly.
CAUTION
 The tire pressure sensors can be
damaged by the installation or
removal of tires. When tires must
be repaired or replaced, we highly
recommend that you have them
repaired or replaced by an autho-
rized SUZUKI dealer.
 Do not use liquid sealants for a flat
tire as air pressure sensors can be
damaged.
 If the low tire pressure warning
light comes on frequently, there
may be something wrong with one
of the tires or with the monitoring
system. Have your vehicle
inspected by an authorized SUZUKI
dealer.

 When the TPMS sensor’s electronic sig-
nal is disturbed in one of the following
ways:
– Electric devices or facilities using simi-
lar radio wave frequencies are nearby.
– A lot of snow or ice covers the vehicle,
in particular, around the wheels or
wheel housings.
– Snow tires or tire chains are used.
 When you use non-genuine SUZUKI
wheels or tires.Replacing Tires and/or WheelsIf you get a flat tire, Suzuki recommends
that you have an authorized SUZUKI
dealer mount a new tire on the wheel that
had the flat tire, and reinstall this tire on the
vehicle in place of the spare. The TPMS is
already set up to recognize the ID code of
the original wheel, and normal TPMS oper-
ation will be restored.
If you need to replace original wheels on
your vehicle, your dealer must make sure
that TPMS sensors are installed in the new
wheels and must set up the TPMS to rec-
ognize the new sensors.
NOTE:
A TPMS sensor is not installed in the spare
tire. You should use the spare tire only in
an emergency situation, and should
replace the spare tire as soon as possible
to restore normal TPMS operation.

Break-In
WARNING
Only use tires and wheels recom-
mended by SUZUKI as standard or
optional equipment for your vehicle.
Use of tires or wheels not recom-
mended by SUZUKI can result in
TPMS failure. Refer to “Tires” in the
“INSPECTION AND MAINTENANCE”
section for additional information.
CAUTION
The future performance and reliabil-
ity of the engine depends on the care
and restraint exercised during its
early life. It is especially important to
observe the following precautions
during the initial 960 km (600 miles)
of vehicle operation.
 After starting, do not race the
engine. Warm it up gradually.
 Avoid prolonged vehicle operation
at a constant speed. Moving parts
will break in better if you vary your
speed.
 Start off from a stop slowly. Avoid
full throttle starts.
 Avoid hard stopping, especially
during the first 320 km (200 miles)
of driving.
 Do not drive slowly with the tran-
saxle in a high gear.
 Drive the vehicle at moderate
engine speeds.

12-3GENERAL INFORMATION
80J21-03E
On-Board Vehicle Computers
and Event Data RecordersYour vehicle is equipped with on-board
computer systems which monitor and
control several aspects of vehicle per-
formance, including the following:
 Emission-related components and
engine parameters such as engine
speed and throttle position are moni-
tored to provide emissions control
and to provide optimum fuel econ-
omy. Your vehicle also has an on-
board diagnostic system which mon-
itors and records information about
emission-related malfunctions.
 Signals from various sensors are
monitored to provide air bag deploy-
ment.
 If your vehicle is equipped with
antilock brakes, conditions such as
vehicle speed and brake perfor-
mance are monitored, so that the
ABS system can provide effective
antilock braking. If your vehicle has
an Electronic Stability Program
(ESP
®) system, conditions such as
yaw rate, lateral acceleration, and
brake fluid pressure are monitored,
so that the ESP
® system can help
the driver control the vehicle in diffi-
cult driving situations.
Some information may be stored by
the on-board computers during normaloperation of the vehicle. This stored
information can assist technicians in
repairing the vehicle when malfunc-
tions occur. Other information is stored
only in the event of crash, by computer
systems that are commonly called
Event Data Recorders (EDRs).
In a crash event, EDRs such as the
Airbag Sensing and Diagnostic Mod-
ule (SDM) in your vehicle may record
information about the condition of the
vehicle and how it was operated, such
as data related to airbag readiness,
airbag performance, safety belt usage,
and the severity of the collision. These
data can help provide a better under-
standing of the circumstances in which
crashes and injuries occur and lead to
the designing of safer vehicles. The
SDM in your vehicle does not collect
or store personal information.
To read the stored information, special
equipment is needed and access to
the vehicle or storage device is
required. SUZUKI will not access infor-
mation about a crash event or share it
with others other than with the consent
of the vehicle owner or lessee, in
response to an official request from
the police or similar government office,
as part of SUZUKI’s defense of litiga-
tion through the discovery process, or
as required by law.In addition, once SUZUKI collects or
receives data, SUZUKI may use the
data for research conducted by
SUZUKI, make the data available for
outside research if need is shown and
confidentiality is assured, or make
summary data which does not identify
specific vehicles available for outside
research.
Others, such as law enforcement per-
sonnel, may have access to the spe-
cial equipment that can read the
information if they have access to the
vehicle or storage device.
