STARTING AND OPERATING115
TOW N GO — IF EQUIPPED
Tow N Go combines the capabilities of the vehicle
control systems, along with driver input, to provide
optimum performance for road conditions.
Push any one of the four drive mode buttons to
select the desired mode.

Drive Mode Buttons
Tow N Go consists of the following positions:TRACK
– Track mode optimizes settings for
transmission, engine, driveline, and suspension
in order to maximize vehicle performance. Also
the electric power steering offers more feed -
back of the tire gripping the road. This feature
will reset to AUTO upon an ignition cycle. To turn
off Electronic Stability Control (ESC)
Ú page 192.
SPORT – Dry weather, on-road calibration.
Performance based tuning that provides a
rear-wheel drive feel but with improved handling
and acceleration over a two-wheel drive vehicle.
This feature will reset to AUTO upon an ignition
cycle.
TOW – Tow drive mode also optimizes the trans -
mission shifting for towing, as well as maxi -
mizing straight line traction by optimizing
driveline settings on AWD system. Use this
mode for towing/hauling. Vehicle suspension
will go to SPORT mode. Trailer Sway Control
(TSC) is enabled in the ESC system. This feature
will reset to AUTO upon an ignition cycle.
SNOW – Tuning set for additional stability in
inclement weather. Use on and off-road on
loose traction surfaces such as snow. This
feature will reset to AUTO upon an ignition cycle.
GUIDELINES FOR TRACK USE
If your vehicle is equipped with Drive Modes,
they will alter the vehicle’s performance in
various driving situations. It is recommended
that your vehicle operates in SPORT or TRACK
modes during the track event.
Prior to each track event, verify all fluids are at
the correct levels.
Prior to each track event, verify the front and
rear brake pads have more than half pad thick -
ness remaining. If the brake pads require
changing, complete a brake burnish procedure
prior to track outing at full pace.
NOTE:Use of DOT 4 brake fluid is suggested for extended
track usage due to increased thermal capacity.
At the conclusion of each track event, it is
recommended that a brake bleed procedure is
performed to maintain the pedal feel and stop -
ping capability of your Brembo High Perfor -
mance brake system.
It is recommended that each track outing
should end with a minimum of one cooldown lap
using minimal braking.
It is recommended that the suspension system,
brake system, prop shaft, and half shaft boots
be checked for wear or damage after every track
event.

STARTING AND OPERATING157
OFF-ROAD DRIVING TIPS
When To Use 4WD Low — If Equipped
When off-road driving, shift to 4WD Low for
additional traction. This range should be limited to
extreme situations such as deep snow, mud, or
sand where additional low speed pulling power is
needed. Vehicle speeds in excess of 25 mph
(40 km/h) should be avoided when in 4WD Low.
Driving Through Water
Although your vehicle is capable of driving through
water, there are a number of precautions that
must be considered before entering the water. Driving through water more than a few inches/
centimeters deep will require extra caution to
ensure safety and prevent damage to your vehicle.
If you must drive through water, try to determine
the depth and the bottom condition (and location
of any obstacles) prior to entering. Proceed with
caution and maintain a steady controlled speed
less than 5 mph (8 km/h) in deep water to
minimize wave effects.
Flowing Water
If the water is swift flowing and rising (as in storm
run-off), avoid crossing until the water level
recedes and/or the flow rate is reduced. If you
must cross flowing water avoid depths in excess of
9 inches (23 cm). The flowing water can erode the
streambed, causing your vehicle to sink into
deeper water. Determine exit point(s) that are
downstream of your entry point to allow for drifting. Standing Water
Avoid driving in standing water deeper than
20 inches (51 cm), and reduce speed
appropriately to minimize wave effects. Maximum
speed in 20 inches (51 cm) of water is less than
5 mph (8 km/h).
Maintenance
After driving through deep water, inspect your
vehicle fluids and lubricants (engine oil,
transmission oil, axle, transfer case) to ensure the
fluids have not been contaminated. Contaminated
fluid (milky, foamy in appearance) should be
flushed/changed as soon as possible to prevent
component damage.
Driving In Snow, Mud And Sand
In heavy snow, when pulling a load, or for
additional control at slower speeds, shift the
transmission to a low gear and shift the transfer
case to AWD Low if necessary Ú
page 112. Only
shift into a lower gear to maintain forward motion.
Over-revving the engine can spin the wheels and
traction will be lost.
Avoid abrupt downshifts on icy or slippery roads,
because engine braking may cause skidding and
loss of control.
.
WARNING!
Do not drive in 4WD Low on dry pavement;
driveline damage may result. 4WD Low locks
front and rear drivelines together and does not
allow for differential action between the front to
rear driveshafts. Driving in 4WD Low on
pavement will cause driveline binding; use only
on wet or slippery surfaces.
CAUTION!
When driving through water, do not exceed
5 mph (8 km/h). Always check water depth
before entering as a precaution, and check all
fluids afterward. Driving through water may
cause damage not covered by the New Vehicle
Limited Warranty.

284SERVICING AND MAINTENANCE
AUTOMATIC TRANSMISSION
Special Additives
The manufacturer strongly recommends against
using any special additives in the transmission.
Automatic Transmission Fluid (ATF) is an
engineered product and its performance may be
impaired by supplemental additives. Therefore, do
not add any fluid additives to the transmission.
Avoid using transmission sealers as they may
adversely affect seals.
Fluid Level Check
The fluid level is preset at the factory and does not
require adjustment under normal operating
conditions. Routine fluid level checks are not
required; therefore the transmission has no
dipstick. An authorized dealer can check your
transmission fluid level using special service tools. If you notice fluid leakage or transmission
malfunction, visit an authorized dealer
immediately to have the transmission fluid level
checked. Operating the vehicle with an improper
fluid level can cause severe transmission damage.
Fluid And Filter Changes
Under normal operating conditions, the fluid
installed at the factory will provide satisfactory
lubrication for the life of the vehicle.
Routine fluid and filter changes are not required.
However, change the fluid and filter if the fluid
becomes contaminated (with water, etc.), or if the
transmission is disassembled for any reason.
To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that
has been in a tightly closed container. Keep
the master cylinder reservoir cap secured at
all times. Brake fluid in a open container
absorbs moisture from the air resulting in a
lower boiling point. This may cause it to boil
unexpectedly during hard or prolonged
braking, resulting in sudden brake failure. This
could result in a collision.
Overfilling the brake fluid reservoir can result
in spilling brake fluid on hot engine parts,
causing the brake fluid to catch fire. Brake
fluid can also damage painted and vinyl
surfaces, care should be taken to avoid its
contact with these surfaces.
Do not allow petroleum based fluid to contam
-
inate the brake fluid. Brake seal components
could be damaged, causing partial or
complete brake failure. This could result in a
collision.
WARNING!
CAUTION!
Do not use chemical flushes in your
transmission as the chemicals can damage your
transmission components. Such damage is not
covered by the New Vehicle Limited Warranty.
CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An authorized
dealer has the proper tools to adjust the fluid
level accurately.

SERVICING AND MAINTENANCE285
Selection Of Lubricant
It is important to use the proper transmission fluid
to ensure optimum transmission performance and
life. Use only the manufacturer's specified
transmission fluid Úpage 323. It is important to
maintain the transmission fluid at the correct level
using the recommended fluid.
NOTE:No chemical flushes should be used in any trans -
mission; only the approved lubricant should be
used.
FRONT/REAR AXLE FLUID
For normal service, periodic fluid level checks are
not required. When the vehicle is serviced for other
reasons the exterior surfaces of the axle assembly
should be inspected. If gear oil leakage is
suspected inspect the fluid level.
Front Axle Fluid Level Check
The front axle oil level needs to be no lower than
1/8 inch (3 mm) below the bottom of the fill hole.
The front axle fill and drain plugs should be
tightened to 22 to 29 ft lbs (30 to 40 N·m).
Rear Axle Fluid Level Check
The rear axle oil level needs to be no lower than
1/8 inch (3 mm) below the bottom of the fill hole.
The rear axle fill and drain plugs should be
tightened to 22 to 29 ft lbs (30 to 40 N·m).
Selection Of Lubricant
Use only the manufacturer's recommended fluid
Ú page 323.
TRANSFER CASE
Fluid Level Check
For normal service, periodic fluid level checks are
not required. When the vehicle is serviced for other
reasons the exterior surfaces of the transfer case
assembly should be inspected. If oil leakage is
suspected inspect the fluid level.
Adding Fluid
With the vehicle in a level position, fill the transfer
case to bottom edge of fill plug opening.
Drain
First remove fill plug, then remove drain plug.
Recommended tightening torque for drain and fill
plugs is 15 to 25 ft lbs (20 to 34 N·m).
Selection Of Lubricant
Use only the manufacturer's recommended fluid
Úpage 323.
CAUTION!
Using a transmission fluid other than the
manufacturer recommended fluid may cause
deterioration in transmission shift quality and/or
torque converter shudder Ú page 323.
CAUTION!
Do not overtighten the plugs as it could damage
them and cause them to leak.
CAUTION!
Do not overtighten the plugs as it could damage
them and cause them to leak.
CAUTION!
When installing plugs, do not overtighten. You
could damage them and cause them to leak.
