Starting the Engine
Starting the Engine
Keep your foot firmly on the brake pedal when
starting the engine.
The engine is harder to start in cold weather and
in thinner air found at altitudes above 8,000 feet
(2,400 meters).
When starting the engine in cold weather, turn
off all electrical accessories (the lights, heating
and cooling system, and rear defogger) in order to
reduce battery drain.
If you live in a region where winter is extremely
cold, an engine block heater will improve starting
and warming of the engine. If temperatures
consistently below -22°F (-30°C) are expected, the
coolant mixture should be changed to a higher
concentration to prevent freezing. Consult a dealer
for details.
If the exhaust system sounds abnormal or you
can smell exhaust gas inside the vehicle, have
your vehicle checked by a dealer. There may be a
problem with the engine or exhaust system.
Brake Pedal
1. Make sure the parking brake is applied.
2. Check that the shift lever is in P
, then
depress the brake pedal.
Although it is possible to start the vehicle
in
N, it is safer to start it in P.

Temporarily Repairing a Flat Tire
This vehicle is not equipped with a spare tire. If the tire has a large cut or is
otherwise severely damaged, you will need to have the vehicle towed. If the tire
only has a small puncture, from a nail for instance, you can use the temporary tire
repair kit so that you can drive to the nearest service station for a more permanent
repair.
If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually
to reduce speed. Then stop in a safe place.
1. Park the vehicle on firm, level, and non-slippery surface and apply the parking
brake.
2. Put the shift lever in
P.
3. Turn on the hazard warning lights and turn the ignition switch to LOCK
0.
When towing a trailer, unhitch the trailer.
