Driving on snow and ice
A 4WD vehicle has advantages over 2WD vehicles in snow and ice but
can skid like any other vehicle.
Avoid sudden applications of power and quick changes of direction on
snow and ice. Apply the accelerator slowly and steadily when starting
from a full stop.
When braking, apply the brakes as you normally would. In order to allow
the anti-lock brake system (ABS) to operate properly, keep steady
pressure on the brake pedal.
Make sure you allow sufficient distance between you and other vehicles
for stopping. Drive slower than usual and consider using one of the lower
gears.
DRIVING THROUGH WATER
If driving through deep or standing
water is unavoidable, proceed very
slowly especially when the depth is
not known. Never drive through
water that is higher than the bottom
of the wheel rims (for cars) or the
bottom of the hubs (for trucks).
When driving through water, traction or brake capability may be limited.
Also, water may enter your engine’s air intake and severely damage your
engine or your vehicle may stall.Driving through deep water where
the transmission vent tube is submerged may allow water into the
transmission and cause internal transmission damage.
Once through the water, always dry the brakes by moving your
vehicle slowly while applying light pressure on the brake pedal.
Wet brakes do not stop the vehicle as quickly as dry brakes.

When driving with the full-size dissimilar spare tire/wheel additional
caution should be given to:
•Towing a trailer
• Driving vehicles equipped with a camper body
• Driving vehicles with a load on the cargo rack
Drive cautiously when using a full-size dissimilar spare tire/wheel and
seek service as soon as possible.
Full-size Matching Spare Tire/Wheel Information
This spare tire/wheel will match the road tire/wheel. When driving with
the full size matching spare tire/wheel, do not exceed 70 mph (113
km/h). It is intended for temporary use only. This means if you need to
use it, you should replace it as soon as possible.
Location of the spare tire and tools
Note: The tire pressure monitoring system (TPMS) indicator light will
illuminate when the spare is in use. To restore the full functionality of
the TPMS system, all road wheels equipped with the tire pressure
monitoring sensors must be mounted on the vehicle.
Have a flat tire serviced by an authorized dealer in order to prevent
damage to the TPMS sensor, refer to Tire Pressure Monitoring System
(TPMS) in theTires, Wheel and Loading chapter. Replace the spare
tire with a road tire as soon as possible.
The spare tire and tools for your vehicle are stowed in the following
locations:
Tool Location
Spare tire Under the vehicle, just forward of the rear bumper
Jack, jack handle, wheel nut wrench Regular Cab: behind seats and underneath
the jack and tools cover
Cab Plus 4–Door: stowed behind the front
seats, between jump seats and underneath
jack and tools cover. The lug wrench is
held in place with a wingnut.
Key, spare tire lock (if equipped) In the glove box

Removing the spare tire1. Assemble the jack handle to the lug wrench as shown in the illustrations.
When connecting the jack handle, assemble the following:
• one handle extension and one
typical extension. To assemble,
slide parts together. To
disconnect, depress button and
pull apart.
• one wheel nut wrench. Depress
button and slide together.
2. If equipped, unlock and remove the spare tire carrier lock from
the rear access hole located just
above the rear bumper and
below the tailgate.

3. Insert the square end of thejack handle into the rear access
hole located just above the rear
bumper and below the tailgate.
Forward motion will stop and
resistance to turning will be felt
when properly engaged. 4. Turn the handle counterclockwise until tire is
lowered to the ground and the
cable is slightly slack.
5. Remove the retainer from the spare tire.
Tire change procedure WARNING: When one of the front wheels is off the ground, the
transmission alone will not prevent the vehicle from moving or
slipping off the jack, even if the vehicle is in P (Park)
(automatic transmission) or R (Reverse) (manual
transmission).
WARNING: To help prevent the vehicle from moving when you
change a tire, be sure the parking brake is set, then block (in
both directions) the wheel that is diagonally opposite (other
side and end of the vehicle) to the tire being changed.
WARNING: If the vehicle slips off the jack, you or someone
else could be seriously injured.
