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

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.

unconsciousness and even
death. Never run the engine
in an enclosed area that has
no fresh air ventilation. For
more information, see
Engine Exhaust0256.
{Warning
Overinflating a tire could
cause the tire to rupture
and you or others could be
injured. Be sure to read and
follow the tire sealant and
compressor kit instructions
and inflate the tire to its
recommended pressure. Do
not exceed the
recommended pressure.
{Warning
Storing the tire sealant and
compressor kit or other
equipment in the passenger
(Continued)
Warning (Continued)
compartment of the vehicle
could cause injury. In a
sudden stop or collision,
loose equipment could strike
someone. Store the tire
sealant and compressor kit
in its original location.
If this vehicle has a tire sealant
and compressor kit, there may
not be a spare tire or tire
changing equipment, and on
some vehicles there may not
be a place to store a tire.
The tire sealant and
compressor can be used to
temporarily seal punctures up
to 6 mm (0.25 in) in the tread
area of the tire. It can also be
used to inflate an
underinflated tire.
If the tire has been separated
from the wheel, has damaged
sidewalls, or has a large
puncture, the tire is too
severely damaged for the tire sealant and compressor kit to
be effective. See Roadside
Assistance Program
0439.
Read and follow all of the tire
sealant and compressor kit
instructions.
The kit includes:
1. Sealant Canister Inlet Valve
2. Sealant/Air Hose
3. Base of Sealant Canister
4. Tire Sealant Canister
5. On/Off Button
6. Slot on Top of Compressor

upright.
Make sure the tire valve
stem is positioned close to
the ground so the hose will
reach it. 6. Remove the valve stem
cap from the flat tire by
turning it
counterclockwise.7. Attach the sealant/airhose (2) to the tire valve
stem by turning it
clockwise until tight.
8. Plug the power plug (9) into the accessory power
outlet in the vehicle.
Unplug all items from other
accessory power outlets.
See Power Outlets 0115. If the vehicle has an
accessory power outlet, do
not use the cigarette
lighter.
If the vehicle only has a
cigarette lighter, use the
cigarette lighter.
Do not pinch the power
plug cord in the door or
window.
9. Start the vehicle. The vehicle must be running
while using the air
compressor.
10. Press the on/off button (5) to turn the tire sealant and
compressor kit on.
The compressor will inject
sealant and air into
the tire.
The pressure gauge (8) will
initially show a high
pressure while the
compressor pushes the
sealant into the tire. Once
the sealant is completely
dispersed into the tire, the
pressure will quickly drop

The pressure gauge (8)
may read higher than the
actual tire pressure while
the compressor is on. Turn
the compressor off to get an accurate pressure
reading. The compressor
may be turned on/off until
the correct pressure is
reached.
Caution
If the recommended
pressure cannot be reached
after approximately
25 minutes, the vehicle
should not be driven farther.
The tire is too severely
damaged and the tire

404 Vehicle Care
Compact Spare Tire
{Warning
Driving with more than one
compact spare tire at a time
could result in loss of
braking and handling. This
could lead to a crash and
you or others could be
injured. Use only one
compact spare tire at a time.
If this vehicle has a compact
spare tire, it was fully inflated
when new; however, it can
lose air over time. Check the
inflation pressure regularly.
It should be 420 kPa (60 psi).
Stop as soon as possible and
check that the spare tire is
correctly inflated after being
installed on the vehicle. The
compact spare tire is designed
for temporary use only. The
vehicle will perform differently
with the spare tire installed
and it is recommended that
the vehicle speed be limited to
80 km/h (50 mph). To conserve the tread of the spare tire,
have the standard tire
repaired or replaced as soon
as convenient and return the
spare tire to the storage area.
When using a compact spare
tire, the AWD (if equipped),
ABS, and Traction Control
systems may engage until the
spare tire is recognized by the
vehicle, especially on slippery
roads. Adjust driving to reduce
possible wheel slip.
Caution
When the compact spare is
installed, do not take the
vehicle through an
automatic car wash with
guide rails. The compact
spare can get caught on the
rails which can damage the
tire, wheel, and other parts
of the vehicle.
Do not use the compact spare
on other vehicles. Do not mix the compact spare
tire or wheel with other
wheels or tires. They will not
fit. Keep the spare tire and its
wheel together.
Caution
Tire chains will not fit the
compact spare. Using them
can damage the vehicle and
the chains. Do not use tire
chains on the compact
spare.

9. Start the engine in the vehicle with the good
battery and run the engine
at idle speed for at least
four minutes.
10. Try to start the vehicle that had the dead battery.
If it will not start after a
few tries, it probably needs
service.
