PARKSENSE REAR PARK ASSIST — IF EQUIPPED
The ParkSense Rear Park Assist system provides visual and
audible indications of the distance between the rear fascia
and a detected obstacle when backing up, e.g. during a
258 STARTING AND OPERATING

the specified GVWR, you must redistribute the weight.
Improper weight distribution can have an adverse effect on
the way your vehicle steers and handles and the way the
brakes operate.
NOTE:Refer to the “Vehicle Certification Label” affixed to
the rear of the driver’s door for your vehicle’s GVWR and
GAWRs.
TRAILER TOWING
Trailer towing is not permitted with this vehicle.
RECREATIONAL TOWING (BEHIND MOTORHOME,
ETC.)
Recreational towing (with all four wheels on the ground, or
using a tow dolly) is NOT ALLOWED. The only accept-
able method for towing this vehicle (behind another ve-
hicle) is on a vehicle trailer with all four wheels OFFthe
ground.
CAUTION!
Towing this vehicle in violation of the above require-
ments can cause severe engine and/or transmission
damage. Damage from improper towing is not covered
under the New Vehicle Limited Warranty.
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.
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 care-
fully whenever there is likely to be poor traction (ice,
snow, wet, mud, loose sand, etc.).
270 STARTING AND OPERATING

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 Differ-
ential (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 pre-
vent damage to your vehicle.
NOTE:
• Due to lower ground clearance, driving your vehicle up
steep driveways, approach ramps or near parking blocks
may cause damage to the front fascia and ground effects.
• Driving through snow more than 4 inches (100 mm)
deep may cause damage to the front fascia and ground
effects.
Flowing/Rising Water
WARNING!
Do not drive on or across a road or path where water is
flowing and/or rising (as in storm run-off). Flowing
water can wear away the road or path’s surface and
cause your vehicle to sink into deeper water. Further-
more, flowing and/or rising water can carry your ve-
hicle away swiftly. Failure to follow this warning may
result in injuries that are serious or fatal to you, your
passengers, and others around you.

STARTING AND OPERATING 271

WARNING!(Continued)
•Never use a tire with a smaller load index or capacity,
other than what was originally equipped on your
vehicle. Using a tire with a smaller load index could
result in tire overloading and failure. You could lose
control and have a collision.
• Failure to equip your vehicle with tires having ad-
equate speed capability can result in sudden tire
failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all seasons (Spring,
Summer, Fall, and Winter). Traction levels may vary be-
tween different all season tires. All season tires can be
identified by the M+S, M&S, M/S or MS designation on the tire sidewall. Use all season tires only in sets of four; failure
to do so may adversely affect the safety and handling of
your vehicle.
Summer Or Three Season Tires — If Equipped
Summer tires provide traction in both wet and dry condi-
tions, and are not intended to be driven in snow or on ice.
If your vehicle is equipped with Summer tires, be aware
these tires are not designed for Winter or cold driving
conditions. Install Winter tires on your vehicle when am-
bient temperatures are less than 40°F (5°C) or if roads are
covered with ice or snow. For more information, contact an
authorized dealer.
Summer tires do not contain the all season designation or
mountain/snowflake symbol on the tire sidewall. Use
Summer tires only in sets of four; failure to do so may
adversely affect the safety and handling of your vehicle.
WARNING!
Do not use Summer tires in snow/ice conditions. You
could lose vehicle control, resulting in severe injury or
death. Driving too fast for conditions also creates the
possibility of loss of vehicle control.

DEPARTMENT OF TRANSPORTATION UNIFORM
TIRE QUALITY GRADES
The following tire grading categories were established
by the National Highway Traffic Safety Administration.
The specific grade rating assigned by the tire’s manu-
facturer in each category is shown on the sidewall of the
tires on your vehicle.
All passenger vehicle tires must conform to Federal
safety requirements in addition to these grades.
Treadwear
The Treadwear grade is a comparative rating, based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded 150 would wear one and one-half
times as well on the government course as a tire graded
100. The relative performance of tires depends upon the
actual conditions of their use, however, and may depart
significantly from the norm due to variations in driving
habits, service practices, and differences in road charac-
teristics and climate.
Traction Grades
The Traction grades, from highest to lowest, are AA, A,
B, and C. These grades represent the tire’s ability to stopon wet pavement, as measured under controlled condi-
tions on specified government test surfaces of asphalt
and concrete. A tire marked C may have poor traction
performance.
WARNING!
The traction grade assigned to this tire is based on
straight-ahead braking traction tests, and does not
include acceleration, cornering, hydroplaning, or
peak traction characteristics.
Temperature Grades
The Temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation of
heat and its ability to dissipate heat, when tested under
controlled conditions on a specified indoor laboratory
test wheel.
Sustained high temperature can cause the material of
the tire to degenerate and reduce tire life, and excessive
temperature can lead to sudden tire failure. The grade C
corresponds to a level of performance, which all pas-
senger vehicle tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades B and A 8
