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.
2WD/i-AWD Switch OperationOperate the 2WD/i-AWD switch according
to the appropriate procedure described
below:
How to turn on 2WD/i-AWD switch
2WD/i-AWD switch will activate when the
ignition switch is turned on.
From 2WD to i-AWD AUTO
Turn the 2WD/i-AWD switch to the neutral
position, and the “i-AWD AUTO” indicator
will come on.

INSPECTION AND MAINTENANCE
80J21-03E
Spark Plugs
65D180
You should inspect spark plugs periodically
for carbon deposits. When carbon accu-
mulates on a spark plug, a strong spark
may not be produced. Remove carbon
deposits with a wire or pin and adjust the
spark plug gap.
To access the spark plugs,
1) disconnect the coupler while pushing
the release lever,
2) remove the bolt, and
3) pull the ignition coil out.

EXAMPLE
CAUTION
 When servicing the iridium/plati-
num spark plugs (slender center
electrode type plugs), do not touch
the center electrode, as it is easy to
damage.
 When installing the spark plugs,
screw them in with your fingers to
avoid stripping the threads. Tighten
with a torque wrench to 25 Nm (2.5
kg-m, 18.0 lb-ft). Do not allow con-
taminants to enter the engine
through the spark plug holes when
the plugs are removed.
 Never use spark plugs with the
wrong thread size.
CAUTION
When replacing spark plugs, you
should use the brand and type speci-
fied for your vehicle. For the speci-
fied plugs, refer to the
“SPECIFICATIONS” section at the
end of this book. If you wish to use a
brand of spark plug other than the
specified plugs, consult your SUZUKI
dealer.

To change a wheel, use the following pro-
cedure:
1) Remove the jack, tools and spare wheel
from the vehicle.
2) Loosen, but do not remove the wheel
nuts.
3) Jack up the vehicle (follow the jacking
instructions in the “EMERGENCY SER-
VICE” section in this manual).
4) Remove the wheel nuts and wheel.
5) Install the new wheel and replace the
wheel nuts with their cone shaped end
facing the wheel. Tighten each nut
snugly by hand until the wheel is
securely seated on the hub.

6) Lower the jack and fully tighten the nuts
(to the specified torque) in a crisscross
fashion with a wrench as shown in the
illustration.Snow TiresYour vehicle is equipped with all-season
tires which are designed for use in summer
and most winter conditions. For improved
traction in severe winter conditions,
SUZUKI recommends mounting radial
snow tires on all four wheels. Snow tires
must be the same size as the standard
tires. Also be sure to use the tires of the
same type and brand on all four wheels of
your vehicle.
