Hydroplaning
Hydroplaning is dangerous. Water
can build up under the vehicle's
tires so they actually ride on the
water. This can happen if the road is
wet enough and you are going fast
enough. When the vehicle is
hydroplaning, it has little or no
contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is to
slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping
equipment in good shape.
.Keep the windshield washer fluid
reservoir filled.
.Have good tires with proper
tread depth. SeeTires on
page 10-42.
.Turn off cruise control.
Highway Hypnosis
Always be alert and pay attention to
your surroundings while driving.
If you become tired or sleepy, find a
safe place to park the vehicle
and rest.
Other driving tips include:
.Keep the vehicle well ventilated.
.Keep the interior
temperature cool.
.Keep your eyes moving —scan
the road ahead and to the sides.
.Check the rearview mirror and
vehicle instruments often.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. Tips for
driving in these conditions include:
.Keep the vehicle serviced and in
good shape.
.Check all fluid levels and brakes,
tires, cooling system, and
transmission.
.Shift to a lower gear when going
down steep or long hills.
{Warning
Using the brakes to slow the
vehicle on a long downhill slope
can cause brake overheating, can
reduce brake performance, and
could result in a loss of braking.
Shift the transmission to a lower
gear to let the engine assist the
brakes on a steep downhill slope.
{Warning
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. This can cause
overheating of the brakes and

Tire and Loading Information
Label
Label Example
1. Number of Occupant SeatingPositions
2. Maximum Vehicle Capacity Weight
3. Size of the Original Equipment Tires
4. Recommended Cold Tire Inflation Pressure
A vehicle-specific Tire and
Loading Information label is
attached to the vehicle's center pillar (B-pillar). The Tire and
Loading Information label shows
the number of occupant seating
positions (1), and the maximum
vehicle capacity weight (2) in
kilograms and pounds.
The Tire and Loading
Information label also shows the
tire size of the original
equipment tires (3) and the
recommended cold tire inflation
pressures (4). For more
information on tires and inflation
see
Tires on page 10-42 and
Tire Pressure on page 10-49.
There is also important loading
information on the Certification
label. It tells you the Gross
Vehicle Weight Rating (GVWR)
and the Gross Axle Weight
Rating (GAWR) for the front and
rear axle. See “Certification
Label” later in this section. “Steps for Determining Correct
Load Limit–
1.Locate the statement "The
combined weight of
occupants and cargo should
never exceed XXX kg or
XXX lbs." on your vehicle’s
placard.
2.Determine the combined
weight of the driver and
passengers that will be riding
in your vehicle.
3.Subtract the combined
weight of the driver and
passengers from XXX kg or
XXX lbs.
4.The resulting figure equals
the available amount of cargo
and luggage load capacity.
For example, if the "XXX"
amount equals 1400 lbs. and
there will be five 150 lb
passengers in your vehicle,
the amount of available cargo

The trailer tongue (1) should weigh
10 percent of the total loaded trailer
weight (2).
After loading the trailer, weigh the
trailer and then the tongue,
separately, to see if the weights are
proper. If they are not, adjustments
might be made by moving some
items around in the trailer.
Total Weight on Your Vehicle's
Tires
Be sure the vehicle's tires are
inflated to the upper limit for cold
tires. These numbers can be found
on the Tire and Loading Information
label. SeeVehicle Load Limits on
page 9-10. Make sure not to go over
the GVW limit for the vehicle,
including the weight of the trailer
tongue.
Trailer Towing (eAssist)
The vehicle is neither designed nor
intended to tow a trailer.
Towing Equipment
Hitches
Use the correct hitch equipment.
See your dealer or a hitch dealer for
assistance.
.The rear bumper on the vehicle
is not intended for hitches. Do
not attach rental hitches or other
bumper-type hitches to it. Use
only a frame-mounted hitch that
does not attach to the bumper.
.Will any holes be made in the
body of the vehicle when the
trailer hitch is installed? If so,
seal the holes when the hitch is
removed. If the holes are not
sealed, dirt, water, and deadly
carbon monoxide (CO) from the
exhaust can get into the vehicle.
See Engine Exhaust on
page 9-26.
Safety Chains
Always attach chains between the
vehicle and the trailer. Cross the
safety chains under the tongue of
the trailer to help prevent the tongue
from contacting the road if it
becomes separated from the hitch.
Leave enough slack so the rig can
turn. Never allow safety chains to
drag on the ground.
Trailer Brakes
Does the trailer have its own
brakes? Be sure to read and follow
the instructions for the trailer brakes
so they are installed, adjusted, and
maintained properly.
Because the vehicle has antilock
brakes, do not tap into the vehicle's
brake system. If this is done, both
brake systems will not work well,
or at all.
