100SAFETY
7. Rotate the steering wheel back to center
and then an additional slightly more than
one-half turn to the right.
8. Place the ignition to the OFF mode and then back to ON. If the sequence was completed
properly, the “ESC OFF Indicator Light” will
blink several times to confirm HSA is
disabled.
9. Repeat these steps if you want to return this feature to its previous setting.
Rain Brake Support (RBS)
Rain Brake Support (RBS) may improve braking
performance in wet conditions. It will
periodically apply a small amount of brake
pressure to remove any water buildup on the
front brake rotors. It functions when the
windshield wipers are in LO or HI speed. When
RBS is active, there is no notification to the
driver and no driver interaction is required.
Ready Alert Braking (RAB)
Ready Alert Braking (RAB) may reduce the time
required to reach full braking during emergency
braking situations. It anticipates when an
emergency braking situation may occur by monitoring how fast the throttle is released by
the driver. The Electronic Brake Controller (EBC)
will prepare the brake system for a panic stop.
Traction Control System (TCS)
The Traction Control System (TCS) monitors the
amount of wheel spin of each of the driven
wheels. If wheel spin is detected, the TCS may
apply brake pressure to the spinning wheel(s)
and/or reduce engine power to provide
enhanced acceleration and stability. A feature
of the TCS, Brake Limited Differential (BLD),
functions similar to a limited slip differential
and controls the wheel spin across a driven
axle. If one wheel on a driven axle is spinning
faster than the other, the system will apply the
brake of the spinning wheel. This will allow more
engine power to be applied to the wheel that is
not spinning. BLD may remain enabled even if
TCS and ESC are in reduced modes.
AUXILIARY DRIVING SYSTEMS
BLIND SPOT MONITORING (BS M) — IF
E
QUIPPED
The Blind Spot Monitoring (BSM) system uses
two radar sensors, located inside the rear
bumper fascia, to detect highway licensable vehicles (automobiles, trucks, motorcycles,
etc.) that enter the blind spot zones from the
rear/front/side of the vehicle.

Rear Detection Zones

When the vehicle is started, the BSM warning
light will momentarily illuminate in both outside
rearview mirrors to let the driver know that the
system is operational.
Automatic Transmission Vehicles
The BSM system sensors operate when the
vehicle is in any forward gear or REVERSE.

STARTING AND OPERATING197
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
Recreational towing (with all four wheels on the
ground, or using a tow dolly) is NOT ALLOWED.
The only acceptable method for towing this
vehicle (behind another vehicle) is on a vehicle
trailer with all four wheels OFF the ground.
DRIVING TIPS
DRIVING ON SLIPPERY SURFACES
Information in this section will aid in safe
controlled launches in adverse conditions.
Acceleration
Rapid acceleration on snow covered, wet, or
other slippery surfaces may cause the driving
wheels to pull erratically to the right or left. This
phenomenon occurs when there is a difference
in the surface traction under the rear (driving)
wheels.
Traction
When driving on wet or slushy roads, it is
possible for a wedge of water to build up
between the tire and road surface. This is
known as hydroplaning and may cause partial
or complete loss of vehicle control and stopping ability. To reduce this possibility, the following
precautions should be observed:
Slow down during rainstorms or when the
roads are slushy.
Slow down if the road has standing water or
puddles.
Replace tires when tread wear indicators first
become visible.
Keep tires properly inflated.
Maintain sufficient distance between your
vehicle and the vehicle in front of you to avoid
a collision in a sudden stop.
Your vehicle may be equipped with a Limited
Slip Differential (LSD) that reduces, but does
not eliminate, the amount of wheel slip across a
given axle for improved handling.
DRIVING THROUGH WATER
Driving through water more than a few inches/
centimeters deep will require extra caution to
ensure safety and prevent damage to your
vehicle.
CAUTION!
Towing this vehicle in violation of the above
requirements can cause severe engine,
transmission and/or transfer case damage.
Damage from improper towing is not covered
under the New Vehicle Limited Warranty.
WARNING!
Rapid acceleration on slippery surfaces is
dangerous. Unequal traction can cause
sudden pulling of the rear wheels. You could
lose control of the vehicle and possibly have a
collision. Accelerate slowly and carefully
whenever there is likely to be poor traction
(ice, snow, wet, mud, loose sand, etc.).

268SERVICING AND MAINTENANCE
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.
ALL WHEEL DRIVE (AWD) — IF
E
QUIPPED
The All Wheel Drive system consists of a
transfer case and front differential. The exterior
surface of these components should be
inspected for evidence of fluid leaks. Confirmed
leaks should be repaired as soon as possible.
The transfer case fluid fill/inspection plug is
located in the middle of the rear housing. To
inspect the transfer case fluid level, remove the
fill/inspection plug. The fluid level should be
even with the bottom of the hole. Use this plug
to add fluid as required. The front differential fill plug is located on the
outer cover near the halfshaft attachment. To
inspect the differential fluid level, remove the fill
plug. The fluid level should be even with or
slightly below the bottom of the hole.
Fluid Changes
Refer to “Scheduled Servicing” in “Servicing
And Maintenance” for the proper maintenance
intervals.
REAR AXLE
Fluid Level Check
Checking the fluid level while the vehicle is on
level ground and has been stationary for
15 minutes will improve the accuracy of the
fluid level reading.
Check the fluid level by removing the fill plug on
the axle. The fluid level should be 1-2.5 mm
below the fill plug. Add fluid, if necessary, to
maintain the proper level. Refer to “Fluids And
Lubricants” in "Servicing And Maintenance” for
further information.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.
