178 DRIVING AND OPERATING
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 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 Control
0 205 and All-Wheel Drive 0200.
Winter Driving
Driving on Snow or Ice
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. Avoid driving on wet ice
or in freezing rain until roads can be
treated.
For Slippery Road Driving:
.
Accelerate gently. Accelerating too
quickly causes the wheels to spin
and makes the surface under the
tires slick.
. Verify Traction Control is on. See
Traction Control/Electronic Stability
Control 0203.
. Antilock Brake System (ABS)
improves vehicle stability during
hard stops, but the brakes should
be applied sooner than when on
dry pavement. See Antilock Brake
System (ABS) 0200.
. Allow greater following distance
and watch for slippery spots. Icy
patches can occur on otherwise

5. The P indicator will turn whiteand the gear indicator on the
shift lever will turn red when the
vehicle is no longer in P (Park).
6. After releasing the shift lever, it will return to the center position.
If the vehicle cannot shift from
P (Park), a Driver Information
Center (DIC) message will be
displayed. See your dealer for service.
Manual Park Release
{Warning
The transmission will be placed in
N (Neutral) when the manual park
release is pulled. The vehicle can
roll and you or others could be
injured. Ensure the vehicle is on
level ground.
Caution
The manual park release is not
intended to be used for towing.
Damage may result from using the
manual park release in this way.
The repairs would not be covered
by the vehicle warranty.
The manual park release can be used
to shift the vehicle into N (Neutral)
when the engine is not running.
Pulling the manual park release while
the vehicle is on or turning the
ignition on while the manual park
release is pulled, will cause a DIC
message to display.
To place the vehicle in N (Neutral)
using the manual park release: 1. Ensure the vehicle is on level ground and set the parking
brake.
2. Turn the vehicle off.
3. Use a flat-bladed tool to remove the interior trim panel on the
center console to the right of the
accelerator pedal.
4. Ensure more than one minute has elapsed since Step 2. Apply
the brake pedal.
