238 Driving and Operating
or under the hood. These
accumulations can be a fire
hazard.
After operation in mud or
sand, have the brake linings
cleaned and checked. These
substances can cause glazing
and uneven braking. Check the
body structure, steering,
suspension, wheels, tires, and
exhaust system for damage
and check the fuel lines and
cooling system for any
leakage.
More frequent maintenance
service is required. See
Maintenance Schedule0425.
Driving on Wet Roads
Rain and wet roads can
reduce vehicle traction and
affect your ability to stop and
accelerate. Always drive
slower in these types of
driving conditions and avoid
driving through large puddles
and deep-standing or flowing
water.
{Warning
Wet brakes can cause
crashes. They might not
work as well in a quick stop
and could cause pulling to
one side. You could lose
control of the vehicle.
After driving through a large
puddle of water or a car/
vehicle wash, lightly apply
the brake pedal until the
brakes work normally.
Flowing or rushing water
creates strong forces.
Driving through flowing
water could cause the
vehicle to be carried away.
If this happens, you and
other vehicle occupants
could drown. Do not ignore
police warnings and be very
cautious about trying to
drive through flowing water.
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. See Tires 0364.

Driving and Operating 239
.Turn off cruise control.
.Activate All-Wheel Drive
(AWD) mode. See Driver
Mode Control0269.
Hill and Mountain
Roads
Driving on steep hills or
through mountains is different
than driving on flat or rolling
terrain. Tips 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
(Continued)
Warning (Continued)
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 loss of
steering assist. Always have
the engine running and the
vehicle in gear.
.Drive at speeds that keep
the vehicle in its own lane.
Do not swing wide or cross
the center line.
.Be alert on top of hills;
something could be in your
lane (e.g., stalled car, crash).
.Pay attention to special road
signs (e.g., falling rocks area,
winding roads, long grades,
passing or no-passing zones)
and take appropriate action.
.Select All-Wheel Drive (AWD)
Mode. See Driver Mode
Control0269 and
All-Wheel Drive 0263.
Winter Driving
Driving on Snow or Ice
Caution
To avoid damage to the
wheels and brake
components, always clear
snow and ice from inside the
wheels and underneath the
vehicle before driving.
Snow or ice between the tires
and the road creates less
traction or grip, so drive
carefully. Wet ice can occur at
about 0 °C (32 °F) when
freezing rain begins to fall.

cooling system, and brake
system before and during
each trip.
Check periodically that all nuts
and bolts on the trailer hitch
are tight.
Engine Cooling When
Trailer Towing
The cooling system may
temporarily overheat during
severe operating conditions.
See Engine Overheating0342.
Trailer Towing
Caution
Towing a trailer improperly
can damage the vehicle and
result in costly repairs not
covered by the vehicle
warranty. To tow a trailer
correctly, follow the
directions in this section and
see your dealer for
important information about
towing a trailer with the
vehicle. Trailering is different than just
driving the vehicle by itself.
Trailering means changes in
handling, acceleration, braking,
durability, and fuel economy.
Successful, safe trailering
takes correct equipment, and
it has to be used properly.
The following information has
many time-tested, important
trailering tips and safety rules.
Many of these are important
for your safety and that of
your passengers. Read this
section carefully before pulling
a trailer.Trailer Weight
{Warning
Never exceed the towing
capacity for your vehicle.
Safe trailering requires
monitoring the weight, speed,
altitude, road grades, outside
temperature, dimensions of
the front of the trailer, and
how frequently the vehicle is
used to tow a trailer.
Trailer Weight Ratings
When towing a trailer, the
combined weight of the
vehicle, vehicle contents,
trailer, and trailer contents
must be below all of the
maximum weight ratings for
the vehicle including:
.Gross Combined Weight
Rating (GCWR)
.Gross Vehicle Weight
Rating (GVWR)
.Maximum Trailer Weight
Rating
.Gross Axle Weight
Rating-Rear (GAWR-RR)
.Maximum Trailer Tongue
Weight Rating

*The Gross Combination Weight Rating (GCWR) is the total allowable weight of the completely
loaded vehicle and trailer including any passengers, cargo, equipment, and conversions. The
GCWR for the vehicle should not be exceeded.
Maximum Trailer Tongue
Weight Rating
The Maximum Trailer Tongue
Weight Rating is the allowable
trailer tongue weight that the
vehicle can support using a
conventional trailer hitch.
It may be necessary to reduce
the overall trailer weight to
stay within the maximum
trailer tongue weight rating
while still maintaining the
correct trailer load balance.
The trailer tongue weight
contributes to the Gross
Vehicle Weight (GVW). GVW
includes the curb weight of
your vehicle, any passengers, cargo, equipment and the
trailer tongue weight. Vehicle
options, passengers, cargo,
and equipment reduce the
maximum allowable tongue
weight the vehicle can carry,
which also reduces the
maximum allowable trailer
weight.
Trailer Load Balance
The correct trailer load
balance must be maintained to
ensure trailer stability.
Incorrect load balance is a
leading cause of trailer sway.

Engine Oil
To ensure proper engine
performance and long life,
careful attention must be paid
to engine oil. Following these
simple, but important steps
will help protect your
investment:
.Use engine oil approved to
the proper specification and
of the proper viscosity
grade. See “Selecting the
Right Engine Oil” in this
section.
.Check the engine oil level
regularly and maintain the
proper oil level. See
“Checking Engine Oil” and
“When to Add Engine Oil” in
this section.
.Change the engine oil at the
appropriate time. See Engine
Oil Life System 0335.
.Always dispose of engine oil
properly. See “What to Do
with Used Oil” in this section.
Checking Engine Oil
Check the engine oil level
regularly, every 650 km
(400 mi), especially prior to a
long trip. The engine oil
dipstick handle is a loop. See
Engine Compartment
Overview0331 for the
location.
{Warning
The engine oil dipstick
handle may be hot; it could
burn you. Use a towel or
glove to touch the dipstick
handle.
If a low oil Driver Information
Center (DIC) message displays,
check the oil level.
Follow these guidelines:
.To get an accurate reading,
park the vehicle on level
ground. Check the engine oil
level after the engine has
